TOP 5 ways to Prepare for your First Job

noreply@blogger.com (learnprogramingbyluckysir) — Sat, 31 Mar 2018 08:40:00 +0000

In this article i am sharing the best ways to prepare for your first jobs. These tips will helpful for freshers.The first job is also a turning point in one’s life. Accepting a new job offer is an exciting moment for any job seeker. It means that you've passed the company's test and it has passed yours and you're on your way to taking the next step in your career.

But smart workers know that landing the job was only half the battle. Just as you researched and prepared for the interview, you'll need to be ready for your first day, so you can walk in with confidence and make a great impression on your new boss and colleagues.

Here are five things you can do to mentally prepare yourself for day one of your new job:

Research your new colleagues and culture:
For any newcomer, it is vital for her/him to play the role of icebreaker. Do not shy away from making the first move to striking up a conversation. “When ‘you’ are the newcomer, do not expect to get a warm reception from your peers,”Spend significant time on the company website before your first day, and look up any events or social media posts the company has or had in the past".Do the best you can to get insights into their culture and history before your first day. This will equip you with different questions to ask and more of a background on the team you have already decided to join."Most importantly, strong connections can help to build your future career path. My advise is Take a few minutes to look up your new supervisors and colleagues,since This will give you a better understanding of their strengths and how you can complement the team's existing talent. It's also a great way to see if you have any overlap in former jobs, colleagues, education and interests, which makes a great conversation starter on your first day."

Be Patient:
Every organization has its own culture and work ethics, and one learns only with time. Before taking up your first job, it is important to be patient and calm. This mindset will make the learning process easier.Being patient doesn’t mean being idle. Relax your mind and utilise the peaceful energy in the right direction.

Clarify expectations with your boss:
Once you've connected with your supervisor, you might want to reach out and ask what he or she expects your first week on the job.You want to be prepared for any travel, important events and priorities that will be hitting your desk right away,That first week is critical for laying the foundation that will define your career at the new company.

Open Minded:

It is always best to begin with an open and flexible mind on your first job. Condition yourself even before the on-boarding process. “Our thoughts and knowledge need to be aligned to meet the desired objective of the role. Even if it means to let go of our current beliefs in order to receive new insights and inputs.

Plan your first day.

Day one of any new job can be overwhelming. There are tons of people to meet, forms to fill out and pieces of information to process. You don't want to arrive stressed because you couldn't find a good outfit to wear or you accidentally missed your bus stop.

"Plan your first-day outfit in advance ... to eliminate any last-minute stresses, and decrease the likelihood of a wardrobe malfunction.You should also check public transportation schedules in advance and scope out some lunch spots so you can really focus on your first day in the office and the responsibilities of your new position."

Is it good time to work in Tele Communication in India?

noreply@blogger.com (learnprogramingbyluckysir) — Wed, 28 Mar 2018 07:42:00 +0000

In this post you will know Why is it a good time to work in telecom?The very fact that almost everybody owns a mobile phone now, along with the on-going digitization of India, should give you the main reason as to why this is one of the best times to work in the telecom industry.

The telecommunications industry is made up of all telephone and internet service providers, which play a big role in improving our mobile communication. It covers everything from voice calls, texting, email, to images and video streaming. The rising growth of this field comes with the demand of skilled employees to facilitate this growth in the best possible manner.

There are 4 million people employed in the telecom sector and by the end of five years, 14.3 million people will be employed in telecom as well as telecom manufacturing,"
Since last year, the telecom sector has already lost around 40,000 jobs and the trend is likely to continue for the next six-nine months, with the total figure expected to reach 80,000-90,000.

Under the National Skill Development Corporation, expects major demand for employment to come from emerging technologies like:

Machine-to-machine communications
Telecom manufacturing
Infrastructure and services companies

The job roles in the telecommunications industry:

The job market in telecom industry can be divided to be in the functional areas and corresponding job roles or positions listed below. Each of these job roles requires specific skills to perform the functional activities:
Network Management Functional Area: Base Station Service Engineer, Core Network Engineer, Field Maintenance Engineer, Transmission Engineer, Optical Fiber Technician, Broadband Installation Engineer, Network Management Engineer, ICT Technician, Network Security Technician.

Educational qualifications required:

The engineering and technician job roles require a 4-year degree in engineering or a polytechnic/ITI background with specific skills training
The sales and service jobs usually would require minimum of class 10 pass with specific skills training
Application and software development requirements may range from engineers to even drop outs with creative competence
Infrastructure segment profiles would hire even school drop outs with high degree of job specific skills

About the growth pattern:

This growth attributes to the penetration of mobile phones and services as well as internet (broadband) connectivity and services
This growth pattern and rate is poised to continue during the next couple of decades because of growth in smart phone sales, 3G and 4G services and rural penetration of telecom services
Telecommunications happens to be an industry where technology changes very rapidly making obsolete the older technologies which cannot provide new and essential as well as lifestyle type services (e.g. use of WhatsApp, banking services, mobile phone as a camera, etc.)
Consequently, the demand for skilled resources in every segment of the telecom industry has been and will continue to be much higher than what the current education or skill development system can supply

Tips to improve interview skills for freshers

noreply@blogger.com (learnprogramingbyluckysir) — Tue, 27 Mar 2018 06:32:00 +0000

In this post i am sharing how to improve interview skills for freshers or beginners. This post helpful who are final year students or freshers. i am going to explain step by step

Always Commit to the Company:

It doesn’t matter if you plan on leaving in 3 years to start your own business. Act like this job will be the last job you will ever need.

Review your own resume.
You know what you did, right? Are you sure? I once got caught off guard in an interview when the hiring manager asked me a specific question about an accomplishment on my resume. I had to stumble for a minute before my brain latched on to what she was talking about. Don't make that mistake. Refresh your memory, especially old jobs.

Pay Attention to Every Question:

Every job interview question the interviewer asks is important, even if it is “what do you think of the weather?” They are all about making a good impression.

Don’t Discuss Salary/Benefits:

Wait until you have the job before you worry about what they pay you.

Remember to Focus on Listening
It can be easy to get distracted during a job interview. It's stressful, and you're in the hot seat when it comes to having to respond to questions.
That said, if you do your best to listen to what the interviewer is asking, it will be easier to frame appropriate responses. Listen carefully and take the time to frame a thoughtful response to each of the questions you're asked.

Be polite to everyone.
You may have heard stories of people who were rude to the receptionist, cut someone off in the parking lot, or yelled at the barista at the coffee shop around the corner and then didn't get the job. These things happen, and they can ruin your chances. I will never, ever, not in a million years hire the person who is rude to the receptionist or barista. Many recruiters and hiring managers feel the same.

Maintain Good Body Language :

Make eye contact throughout the job interview and do not slouch or use any bad posture or bad habits.

Think First :

It is okay to take two or three seconds to think about your answer before you actually provide your answer. The last thing you want to do is ramble about something inconsequential.

Have Questions Ready to Ask
Be prepared to respond when you're asked whether you have any questions. You can ask about the job, the company.

Practice and You Will Be Even Better
The about list is a good resource for those that are in a rush to improve their interview skills. If you have time, however, it is a good idea to try to practice answering interview question as much as possible and utilize many useful job interview strategies.

Don't forget the thank you card.
It doesn't have to be a card anymore; an email will do just fine. You can get hired without one, but it's a nice gesture to send a quick follow up email to the hiring manager and recruiter. It keeps you in their minds and shows your politeness, which brings this full circle. You begin by being nice to everyone, and you end the interview by being nice to everyone, and you increase your chances.

How to imporve programming Skills

noreply@blogger.com (learnprogramingbyluckysir) — Wed, 21 Feb 2018 01:11:00 +0000

In this post you will understand how can i improve programming skills.Programming(coding) is just a part of process of problem solving, You should need to understand the underlying problem and efficient solution within given constraint.Constantly find small problems that you care about which can be solved programmatically and practice, practice, practice.

So i will better tell you,how to be better at problem solving:

Step 1: Learn

Programming Language & Computer science fundamental :-
First & foremost ,you should be proficient in any one of the popular languages(C/C++/Java/Python), I will advise you to chose between c++ or Java ,since both are widely accepted across all coding competitions and have better resources to get yourself trained. Apart from knowing the language
make sure you are pretty good in debugging and testing your own written code
with all the scenarios.

Some of the Resources you can go through it to improve your coding skills:

CodingBat java: www.codingbat.com/java
coursera c++: www.coursera.org/course/cplusplus4c

Data Structure and Algorithm:-
You can be a good programmer if you know a programming language well but to become a great programmer you need to understand underlying data structure and algorithms.

Learn all the basic data structures - array, list, tree, graph, trie, dictionary/map, set, etc.
Learn the advanced data structures whatever you can - suffix array, suffix tree etc.
Implement data structures in whatever languages you know.
Understand the basic operations (read, write, etc,) time complexity for those data structures.
Understand the strength & weaknesses of each of those.
Remember the data structure support by the language libraries (STL, classes etc.).

Algorithms:

Learn all the easy algorithms - sorting, searching, graph algos, etc.
Learn all the advanced algorithms whatever you can - dynamic programming, backtracking, etc.
You need to master algorithm complexity computation.
You need to learn how to design your custom algorithm as per the need.
Keep implementing lots of algorithms

Step 2: Practice

Improve your speed and accuracy in coding by participating in various online resources.

STEP 3: Propagate

Form a study group and keep practicing daily. Try developing your own algorithms/applications; try answering a few questions on Stack Overflow.You can even organize workshops for the juniors in your college.

Finally i could say the following key points:

Write a lots of code, compile, run, debug.
Read lots of code authored by others, may be from popular open source projects.
Keep learning new languages, new data structures, new algorithms, new tools year after year.

switch statement in C

noreply@blogger.com (learnprogramingbyluckysir) — Sat, 17 Feb 2018 14:29:00 +0000

In this post you will learn about switch case statement in C programming language.The control statement that allows us to make a decision from the number of choices is called a switch statement.Switch statement is a control statement that allows us to choose only one choice among the many given choices. The expression in switch evaluates to return an integral value, which is then compared to the values present in different cases. It executes that block of code which matches the case value. If there is no match, then default block is executed(if present).
The general form of switch statement is:

switch(integer expression)
{
    case value-1:
       block-1;
       break;
    case value-2:
       block-2;
       break;
    case value-3:
       block-3;
       break;
    case value-4:
       block-4;
         break;
    default:
         default-block;
       break;
}

Example:

#include<stdio.h>
void main( )
{
    int a, b, c, choice;
    while(choice != 3)
    {
        /* Printing the available options */
        printf("\n 1. Press 1 for addition");
        printf("\n 2. Press 2 for subtraction");
        printf("\n Enter your choice");
        /* Taking users input */
        scanf("%d", &choice);

        switch(choice)
        {
            case 1:
                printf("Enter 2 numbers");
                scanf("%d%d", &a, &b);
                c = a + b;
                printf("%d", c);
                break;
            case 2:
                printf("Enter 2 numbers");
                scanf("%d%d", &a, &b);
                c = a - b;
                printf("%d", c);
                break;
            default:
                printf("you have passed a wrong key");
                printf("\n press any key to continue");
        }
    }
}

Example 2:

int main()
{
int i;
printf("enter an integer");
scanf("%d",&i);
switch(i)
{
case 1: printf("one");
            break;
case 2: printf("two");
            break;
case 3: printf("three");
            break;
case 4: printf("four");
             break;
default: printf("invalid number");
}
return 0;
}
There are some things that you simply cannot do with a switch .
These are:
(a) A float expression cannot be tested using a switch
(b) Cases can never have variable expressions (for example it is
wrong to say case a +3 : )
(c) Multiple cases cannot use same expressions.

How to do final year project for Computer Science students

noreply@blogger.com (learnprogramingbyluckysir) — Thu, 15 Feb 2018 14:55:00 +0000

In this post you will learn the procedure to make final projects for computer science students.
There are four main phases in developing a final year project:

Choosing the right project
Planning and execution of the project
Documentation of the project
Management of the project

Given that you are going to spend a lot of time working on your project, it is essential that you pick a project which you like and which you are capable of doing. It is important to note that these are not necessarily the same things: just because you like a particular project does not mean you are qualified to do it.

Planning and execution of the project

The main activities that comprise of this phase of project development are:

1. Identifying a problem to be solved

2. Generating project requirements

3. Developing a computational model for the solution

4. Performing system analysis

5. Designing of the system

6. Implementing and Integrating the modules

7. Testing the solution

8. Documenting the project

9. Managing the project

A detailed explanation of the above activities is given here:

Steps involved in planning and executing a final year project

Documentation of the project

It is extremely important that you document your work at every stage of your project. The best way to organize your writing is to keep a log book of all work in progress. Every thought and observation you have on your project should go into this book, along with notes of meetings with your supervisor, results, theoretical developments, calculations, everything. This log book will become an invaluable source of material when you come to write up your project in the final report. However, don’t wait until the end of the project to begin the process of formal documentation. Write a formal report on completion of each phase of the project. These reports will become an excellent basis for your final report.

Management of the project

One of them most important things you will learn when doing your project is the need to manage your time. Final Year Projects require a considerable amount of time. A project schedule is an indispensable tool: building it forces you into thinking about all the things you need to do, their inter-relationships, the time each will take, and what each one will be used for. In drawing up your project schedule, you may find it useful to use a standard project management tool (such as Microsoft Project). These tools make it easy to draw the schedule and to track your progress. However, they won’t do the planning for you, i.e. they can’t identify tasks, subtasks, effort, duration, etc. That’s something you have to do yourself.

Personality Development tips for students

noreply@blogger.com (learnprogramingbyluckysir) — Wed, 14 Feb 2018 16:15:00 +0000

Personality is defined as the blend of qualities that makes a person unique from the other folks. It mostly arises from within and makes you who you are. Your personality is judged by your way of talking, confidence,values, behavior and education which makes you interesting and likeable to be with.

First of all it is very important to understand what type of personality you have and then improve and work on it.

So the first thing is to know yourself. Analyze your strengths and weakness. Identify areas you need to work on. Be sincere with yourself.

Have a positive approach to life and situations. Don't just say positive things, but also think positive. Your thoughts, words and action all need to be positive. Try to find some thing positive from every situation.
Learn some new talents, hobbies. Try to do something which you have been avoiding or postponing. Then next time when there is a chance to show your new talent, deliver in front of all.
Share your opinions and ideas with others. Do not be afraid to speak up. This will boost your confidence.
If you are shy, try socialing. Meet new people and involve yourself into large number of things.
Find time to read, listen to something motivational everyday. Even if it is for 10 minutes, it is enough for the day.
If you speak too much, try to listen to others as well. When we listen to others there is greater chance for us to learn something new. Pay full attention when others are speaking and do not get distracted.
Mind your body language. Non verbal communication is as important as verbal communication to enhance your personality. Always walk straight, do not droop. Maintain eye contact while speaking. Your voice should be soft and not very loud and well pitched.

Top Technology trends in 2018

noreply@blogger.com (learnprogramingbyluckysir) — Wed, 14 Feb 2018 15:51:00 +0000

Technology has become a necessity rather than a desire. There are several emerging tech trends that’ll shape a big part of our business and lifestyle in the year 2018.We are surrounded by technology at almost every front of our lives.

Technological innovations are exciting as they promise to change the way the world currently functions. These innovations lead to a better and a more comfortable life for people. Since the last few decades, technology has experienced exponential growth and continues to do so. Technology is a part of our everyday life, right from using showers that provide us the ability to have infotainment while we take a shower to self-driven cars, technology has never failed to amaze its users. Every day there is a possibility of technology coming up with an innovation that was not present just the day before. So, here are five tech trends to watch out for in 2018!.

Taking intelligent things to a new level:

Artificial intelligence and machine learning communicate allows machines to communicate with their users in a manner that eases the user’s life. Artificial intelligence is the base of all smart things that know how to behave in accordance to human expectations and how to learn from them. In the past few months, the creation of bots has been on a rise. As AI is improving itself, people can hope to get introduced to bots and smart devices that understand the concept of collaboration and communication with each other.

Expanding reach of blockchain

Decentralization stands as one of the critical features of blockchain technology. Blockchain as technology has experienced tremendous growth and applications of blockchain exist across numerous industries. There were still few industries that are untouched by the blockchain industry and soon we could experience how blockchain can advance in other sectors thus, easing out our lives.

Enlightening lives with big data

We are in the age of information and organizations are collecting data to help us in times when we need this information the most. During the last few years, big data has experienced impeccable growth and achieved applications across industry with only one aim - making human life better. Often businesses have ample information that can help them increase sales, but they fail in data management. In 2018, people and CTOs can expect more companies to evolve their data management techniques and be able to maintain weight between data control and accessibility.
Taking cloud storage higher

When people refer to cloud storage, flexibility is the first word that comes to their minds. In the last few years, the speed at which cloud storage is growing is being appreciated by organizations across industries. In 2018, people can expect their storage facilities to be faster than the conventional methods.
Converting everything to smart things

IoT is driven by innovation and is a technology that has supplied the world with exceptional products. Some of these products include smartwatches, smartphones, smart TVs, and smart cars. Looking at these products, saying that almost everything can be converted to intelligent things would not be wrong.

These smart devices operate by themselves, without any human intervention, and have led to a more automated human lives. In 2018, people can expect these devices to take a massive leap by automating and converting things that are not smart currently, into smarter things.

What are the Career Opportunities after studying Computer Engineering

noreply@blogger.com (learnprogramingbyluckysir) — Mon, 12 Feb 2018 16:29:00 +0000

In this post you will know, what to do after completion of engineering or graduate.Being a good computer engineer can get you a numerous job options.
Computer science is one of the country’s hottest and most in-demand professional fields, the Bureau of Labor Statistics projected an 18 percent growth nationally for all computer occupations between 2012 and 2022.

Software developers, applications - 23%
Software developers, systems software - 20%
Computer network architects - 15%
Network and computer system admins - 12%
Computer network support specialist - 7%
Computer hardware engineers - 7%

Talk about web development there are three roles that are currently in demand by the IT industry:

Front-end development : HTML, CSS, JavaScript and Angular.js
Back-end development: Ruby, Python, R, Node.js, Cloud etc.
MEAN Stack/Full Stack development :MongoDB, Express.js, Angular.js, Node.js

Here’s to ease your research - giving you few names of the platforms that provides you the learning skills on the latest technology. MOOCs such as Udemy, Edureka, edWisor and Simplilearn etc. are examples of such platforms.

Udacity: they offer upgraded curriculum and great learning skills, certifications and nano degrees, hire talent source but still no job assurance.

Udemy: good learning skills, live sessions and just certifications but no job assurance.

edWisor : a career path, good learning skills, technical sessions, projects and hands-on experience plus a job assurance.
Simplilearn : skills on the said technologies but limit itself only till certifications and no job assurance.

what is the best laptop i can buy as a CS student

noreply@blogger.com (learnprogramingbyluckysir) — Mon, 12 Feb 2018 16:01:00 +0000

In this post you will know which is the best laptop for computer science students.The very basic thing a programmer need is to a laptop which has good speed. The focus should be on the processor speed, it should be minimum 2GHZ or more. The laptop RAM should not be less than 4GB.

The most basic of laptops will get the job done, so anything above that is for your own comfort. To be honest, you can just use the school's lab computers. However, my philosophy has been to go for a lightweight laptop with long battery life, as high a resolution screen as you can get, and a good keyboard.

Apple MacBook Pro 13" or MacBook Air (11" or 13")
Dell Vostro 1440, 3450, and V131
Lenovo Thinkpad T and X series
Toshiba Portege R830 and R835

The MacBooks are nice , but you'll probably load Windows on them, just to keep things easy. Keep in mind that you will buy something new when you graduate, so plan your purchase around what you can afford to replace in 2 years. Processing power, HD capacity, etc. are not important, especially for a computer that can easily get stolen or broken.

Also, if you end up taking any digital logic courses, you will want a few extra USB ports and will definitely need Windows, because most of the IDEs for FPGAs and micro controllers are only available on Windows.

The very basic thing a programmer need is to a laptop which has good speed. The focus should be on the processor speed, it should be minimum 2GHZ or more. The laptop RAM should not be less than 4GB.

WHAT TO LOOK FOR IN A LAPTOP FOR PROGRAMMING?

The very basic thing a programmer need is to a laptop which has good speed. The focus should be on the processor speed, it should be minimum 2GHZ or more. The laptop RAM should not be less than 4GB.

Laptop Starting price in India:

I will say the specs or some of the features to watch out for when buying a laptop. Because, the same model with the same specs is not available in all parts of the world.

CPU : Intel i5/i7 (6th/7th gen preferably, and buy one with a quad-core rather than a dual-core processor)

RAM : Minimum 8 gigs, buy one with 1*8 GB rather than 2*4 GB , with an expandable slot.

Display : Full HD (either 13.3 or 15.6 inches) , you’ll clear notice that there’s a great difference between the 1366*768 and the 1920*1080 displays.

GPU -:Nvidia GTX series graphics (only if you are a gamer and do some heavy Photoshop work, else the built in Intel HD graphics would suffice)

HDD :1 Terabyte. SSD’s are costlier, but they reduce boot time.

Backlit keyboard : They are definitely useful when you work during late hours. The keyboard layout is very important since certain laptops with tightly packed keys are not comfortable for typing.

OS :Instead of buying one with Windows, choose one with the DOS or Linux. It will definitely save you few thousand bucks and you can always install an OS later as per your wish.

Ports -:USB 3.0, HDMI ports are a must, type-C port is a bonus.
Laptops with ultrabays are better since they can be used in multiple ways (GPU/Optical Drive/SSD)

Optical drive : Not necessary as the CD’s and DVD’s are replaced by USB drives nowadays.

The Macbooks are very good for programming but if you are looking for a laptop for coding/designing/playing games/watching movies you should consider an alternative. The Thinkpad series of Lenovo, Envy series of Hewlett-Packard and the Dell ultrabooks are very good options to consider for CS students.

JQuery Interview Questions and answers

noreply@blogger.com (learnprogramingbyluckysir) — Thu, 08 Feb 2018 00:56:00 +0000

In this post you will learn frequently asked JQUERY interview questions for freshers and Experienced candidates.

1. what is jQuery?

ans: JQuery is javascript library or javascript framework which helps in how to traverse HTML documents,to do animations,and add Ajax interaction to any web page. It is mainly used to reduce lines of code as huge code written in javascript,can be done easily with JQuery in few lines.

2. What does $ mean in JQuery?

ans: Dollar sign is nothing but it's an alias for jQuery. see the below jQuery code

$(document).ready(function)
{
});

here $ sign can be replaced with "jQuery"keyword like
jQuery(document).ready(functioin)
{
});

3)What are the advantage of using jQuery?

ans:

Easy to use and learn.
Easily expandable.
Cross-browser support (IE 6.0+, FF 1.5+, Safari 2.0+, Opera 9.0+)
Easy to use for DOM manipulation and traversal.
Large pool of built in methods.
AJAX Capabilities.
Methods for changing or applying CSS, creating animations.
Event detection and handling.
Tons of plug-ins for all kind of needs.

4)Why you should be using jQuery?
Ans:
Based on the manipulation of the HTML DOM (Document Object Model) and designed to simplify the client-side scripting of HTML, jQuery incorporates parts of HTML and CSS. Thousands of companies and individuals are on the jQuery bandwagon, and you should be, too.

5)How JavaScript and jQuery are different?
ans:
jQuery is not a programming language but a well written JavaScript code. It is a library/framework built with Javascript. It is very popular because it (nearly universally) abstracts away cross-browser compatibility issues and it emphasises unobtrusive and callback-driven Javascript programming. Javascript is the core programming language.

6)How you will use Jquery means requirement needed for using jquery?
ans:
Nothing more need to do just olny download jquery library(.js file) from any of the jquery site Download jquery and just linked with your html pages like all other javascript file
as follows:
code:
< script src="jquery.js" language="javascript" type="text/javascript">

7)How do you select an item using css class or ID and get the value by use of jquery?
ans:
If an element of html like < div> , < p> or any tag have ID MyId and class used MyClass then we select the element by below jquery code

Code:
$('#MyId') for ID and for classs $('.MyClass')
and for value
Code:
var myValue = $('#MyId').val();
// get the value in var Myvalue by id
Or for set the value in selected item
Code:
$('#MyId').val("print me");
// set the value of a form input

8)How to get the server response from an AJAX request using Jquery?
ans:
When invoking functions that have asynchronous behavior We must provide a callback function to capture the desired result. This is especially important with AJAX in the browser because when a remote request is made, it is indeterminate when the response will be received.
Below an example of making an AJAX call and alerting the response (or error):
Code:
$.ajax({
     url: 'EmpRecords.php',
     success: function(response) {
        alert(response);
     },
     error: function(xhr) {
        alert('Error! Status = ' + xhr.status);
     }
});

9)What is $(document).ready() function? Why should you use it?
ans:
This is one of the most important and frequently asked jQuery Interview question. The ready() function is used to execute code when document is ready for manipulation. jQuery allows you to execute code, when DOM is fully loaded i.e. HTML has been parsed and DOM tree has been constructed. Main benefit of $(document).ready() function is that, it works in all browsers, jQuery handles cross browser difficulties for you.

10)Difference between JavaScript window.onload event and jQuery ready function?
ans:

Main difference between JavaScript onload event and jQuery ready function is that former not only waits for DOM to be created but also waits until all external resources are fully loaded including heavy images, audios and videos. If loading images and media content takes a lot of time, the user can experience significant delay on execution of code defined in window.onload event.

On the other hand jQuery ready() function only waits for the DOM tree, and does not wait for images or external resource loading, which means faster execution. Another advantage of using jQuery $(document).ready() is that you can use it multiple times in your page, and browser will execute them in the order they appear in HTML page, as opposed to onload technique, which can only be used for a single function. Given this benefits, it’s always better to use jQuery ready() function than JavaScript window.onload event.

11)what are the different types of selectors in JQuery?
ans:
There are 3 types of selectors in jquery
1.css selector
2.XPath selector
3.Custom selector

12)How can you select all elements in a page using jquery?
ANS:
To select all elements in a page,we can use all selectors,for that we need to use * symbol

code:
<script language="javascript" type="text/javascript">
$("*").css("border","2px dotted blue");
</script>

13)What are jQuery Events?
ans:
Events are actions performed on a specific condition that are used for dynamic web pages. When we perform these actions on an HTML page, we can do whatever we want. We use some event handlers to perform the action. Some important handlers are bind(), unbind(), blur(), off(), hover(), on(), one(), ready(), trigger() etc.

14)What are jQuery plugins and what is the advantage of using a plugin?
ans:
A plug-in is piece of code written in a standard JavaScript file. These files provide useful jQuery methods which can be used along with jQuery library methods. jQuery plugins are quite useful as its piece of code which is already written by someone and re-usable, which saves your development time.

15)What is the difference between .empty(), .remove() and .detach() methods in jQuery?
ans:

All these methods .empty(), .remove() and .detach() are used for removing elements from DOM but they all are different.

.empty(): This method removes all the child element of the matched element while remove() method removes set of matched elements from DOM.

.remove(): We use .remove() when we want to remove the element itself, as well as everything inside it. In addition to the elements themselves, all bound events and jQuery data associated with the elements are removed.

.detach(): This method is the same as .remove(), except that .detach() keeps all jQuery data associated with the removed elements. This method is useful when removed elements are to be reinserted into the DOM at a later time.

16)What is the difference between bind() and live() method in jQuery?
ans:
The binding of event handlers are the most confusing part of jQuery for many developers working on jQuery projects. Many of them unsure of which is better to use. In this article we will see the main differences between Bind and Live methods in jQuery.

Bind() Method
The bind method will only bind event handlers for currently existing items. That means this works for the current element.

$(document).ready(function () {
$('p').bind('click', function () {
alert("Example of Bind Method");
e.preventDefault();
});

Live() Method
The Live method can bind event handlers for currently existing items or future items.

$(document).ready(function() {
$('P').live('click', function() {
alert("Example of live method");
e.preventDefault();
});
$('body').append(''); });

17)What is the difference between eq() and get() methods in jQuery?
ans:
eq() returns the element as a jQuery object. This method constructs a new jQuery object from one element within that set and returns it. That means that you can use jQuery functions on it.

get() returns a DOM element. The method retrieves the DOM elements matched by the jQuery object. But it is a DOM element and it is not a jQuery-wrapped object. So jQuery functions can’t be used.

PHP Login Form using Session

noreply@blogger.com (learnprogramingbyluckysir) — Wed, 07 Feb 2018 13:31:00 +0000

In this post you will learn login form source code using session without storing details in the database. In our next post you will see login form using session storing details in database.

Step 1: First create login page named as index.php

<?php>
session_start();    // Session start
if(isset($_POST['check']))    // Check form submit with IF Isset function
{
$username="lucky";    // set variable value
$password="123";        // set variable value
if($_POST['username']==$username && $_POST['password']==$password)   // Check Given user name, password and Variable user name password are same
{
$_SESSION['username']=$username;    // set session from given user name
header('location:mainpage.php');
}
else
{
$err="Authentication Failed Try again!";
}
}
?>
<html>
<head>
<title>Main Page</title>
</head>
<body>
<Center>
<?php if(isset($err)){ echo $err; } ?>      

<form method="POST" name="loginauth" target="_self">
User Name: <input name="username" size="30" type="text" />
<br/><br/>
Pass Word: <input name="password" size="20" type="password" />
<br/><br/>
<input name="check" type="submit" value="Authenticate" />
</form>
</center>
</body>
</html>

Step 2: Now create mainpage.php

<?php
session_start();    //session start
if(!isset($_SESSION['username']))     //if session not found redirect to homepage
{
header('location:index.php');
}
echo "Welcome  ";
echo $_SESSION['username'];      //retrieved using session
?>
<html>
<head>
</head>
<body>
<center>
<h2>Welcome to Main page</h2>
<a href="logout.php">logout</a>
</center>
</body>
</html>

Step 3: Now create LOGOUT.PHP page for destroy the session

<?php
session_start();
if(!isset($_SESSION['username']))     //if session not found redirect to homepage
{
header('location:index.php');
}
unset($_SESSION['username']);       // Session Found Unset the variable values
session_destroy();                  // Destroy the session
header('location:index.php');
?>

What is Web based Applications in cloud computing

noreply@blogger.com (learnprogramingbyluckysir) — Wed, 17 Jan 2018 01:30:00 +0000

In this post we will learn what is web based application and their benefits. At the same time we will also known what are the essentials of creating web-based applications and what the IT department needs.

Web Application:

In computing, web application or web app is a client-server computer program in which client runs in a web browser. A web based application is any application that uses a website as a interface or front end. Users can easily access from any computer connected to the internet using a standard browser.

why develop web-based application?

They must be deliver adequate computing power and data storage to all users within the company.
Must be done,of course,within a set of budget
to meet peak need or to add capacity for new users

What are the essentials of creating web-based applications?

web based application development is not just the way to save money and time
organizing more effective collaboration process with your colleagues,clients or partners, that makes web based application development
web based application development includes database integration,intra-and extranet applications deployment

What the IT department needs?

Is a way to increase capacity or add capabilities without investing in new servers and networking gear,or licensing new software. It is to this need that cloud computing speaks

cloud services,in the form of centralized web-based applications
application hosted in the cloud is cheaper and easier to manage than individual copies
upgrading a cloud app only has to be done one time
cloud services development are particularly notable to smaller businesses,who otherwise wouldn't have the budget or resource to develop large scale applications

Python Interview Questions for freshers

noreply@blogger.com (learnprogramingbyluckysir) — Mon, 23 Oct 2017 09:36:00 +0000

In this post we will learn frequently asked Python Interview Questions and answers for freshers and also for experienced developers.In previous post we had discussed about why Python so powerful for Data Science, one of the frequently raised question that one so go through that post as well.

1) What is Python?

Ans: Python is a high level ,Object oriented,most successful interpreted language. It is a portable language,since it can run on different platforms such as Windows,Linux,Unix,Mac...It is a interpreted language that means when write a Python script it doesn't need to get compiled before execution.

2) What are the Benefits of Python?

Ans:

Python is a Object Oriented Programming language as you can define classes along with the composition and Inheritance. It doesn't use any access specifier like Public or private
It provides very high level dynamic data types and supports dynamic type checking
It can be use as Scripting language or can be compiled to byte-code for building large applications.
We can use Python for developing Web applications,automation,Scientific Modeling,Big Data applications etc..
It can be easily integrated with C,C++,JAVA,COBRA,COM .
It is extensible

3) What are the Data types in Python?

Ans: Python has 5 Standard Data types:

Numbers
String
List
Tuple
Dictiornary

4) Is Multithreading supports in Python?

Ans: YES,Python has multi-threading package. It has a Construct called Global Interpreter Lock(GIL). This GIL makes you feeling only one thread is 'executing' at any one time.This happens very quickly so to the human eye it may seem like your threads are executing in parallel, but they are really just taking turns using the same CPU core.This means that if you want to make your code run faster then using the threading package often isn’t a good idea.

5)What is the output of print str if str = ‘Hello World!’?

Ans: Hello World!.

6) How to overload methods in Python?

Ans: Python's constructor:

_init__ () is a first method of a class. Whenever we try to instantiate a object __init__() is automatically invoked by python to initialize members of an object.

7)How To Find Bugs Or Perform Static Analysis In A Python Application?

Ans: You can use PyChecker, which is a static analyzer. It identifies the bugs in Python project and also reveals the style and complexity related bugs.Another tool is Pylint, which checks whether the Python module satisfies the coding standard.

8) How to achieve Inheritance in Python?

Ans: Inheritance allows One class to gain all the members(say attributes and methods) of another class. Inheritance provides code re-usability, makes it easier to create and maintain an application. The class from which we are inheriting is called super-class and the class that is inherited is called a derived / child class.

9) What is the usage of help() and dir() function in Python?

Ans: Help() and dir() both functions are accessible from the Python interpreter and used for viewing a consolidated dump of built-in functions.

Help() function: The help() function is used to display the documentation string and also facilitates you to see the help related to modules, keywords, attributes, etc.

Dir() function: The dir() function is used to display the defined symbols.

10)How is memory managed in Python?

Ans: Python memory is managed by Python private heap space. All Python objects and data structures are located in a private heap. The programmer does not have an access to this private heap and interpreter takes care of this Python private heap.

The allocation of Python heap space for Python objects is done by Python memory manager. The core API gives access to some tools for the programmer to code.

Python also have an inbuilt garbage collector, which recycle all the unused memory and frees the memory and makes it available to the heap space.

11)What is dictionary in Python?

Ans: The built-in datatypes in Python is called dictionary. It defines one-to-one relationship between keys and values. Dictionaries contain pair of keys and their corresponding values. Dictionaries are indexed by keys.

Let’s take an example:

The following example contains some keys. Country, State & Captain. Their corresponding values are India, Andhra and Kohili respectively.

dict={'Country':'India','State':'Andhra','Captain':'kohli'}

print dict[Country]

India

print dict[State]

Andhra

print dict[Captian]

Kohli

12)What is pickling and unpickling in Python?

Ans: Pickling is a process in which a pickle module accepts any Python object, converts it into a string representation and dumps it into a file by using dump() function.

Unpickling is a process of retrieving original Python object from the stored string representation for use.

13) How Python does Compile-time and Run-time code checking?

Ans: In Python some amount of coding is done at compile time, but most of the checking such as type, name, etc. are postponed until code execution. Consequently, if the Python code references a user -defined function that does not exist, the code will compile successfully. The Python code will fail only with an exception when the code execution path does not exist.

14)Which command is used to exit help window or help command prompt?

Ans: "quit" command is used to exit help window or help command prompt.

15)What Is The Key Difference Between A List And The Tuple?

Ans:

The major difference between a list and the tuple is that the list is mutable while tuple is not. A tuple is allowed to be hashed, for example, using it as a key for dictionaries.

16)Is There A Switch Or Case Statement In Python? If Not Then What Is The Reason For The Same?

Ans:

No, Python does not have a Switch statement, but you can write a Switch function and then use it.

17)What Is A Built-In Function That Python Uses To Iterate Over A Number Sequence?

Ans:

range() generates a list of numbers, which is used to iterate over for loops.

Example:

for i in range(5):

print(i)

The range() function accompanies two sets of parameters.

range(stop)

stop: It is the no. of integers to generate and starts from zero. eg. range(4) == [0, 1, 2,3].

range([start], stop[, step])

start: It is the starting no. of the sequence.

stop: It specifies the upper limit of the sequence.

step: It is the incrementing factor for generating the sequence.

Points to note:

Only integer arguments are allowed.

Parameters can be positive or negative.

The <range()> function in Python starts from the zeroth index.

Cloud Computing Interview Questions

noreply@blogger.com (learnprogramingbyluckysir) — Sat, 25 Feb 2017 17:01:00 +0000

In this post i am sharing Cloud Computing Interview Questions. These questions are helpful for freshers and for final year Students. Now a days,Cloud Computing is one one of the important technology. Cloud Computing is the computing which is completely based on the Internet. The main purpose of the cloud computing is that provides the way to deliver the services whenever and wherever the user of the cloud needs.

Companies use the cloud computing to fulfill the needs of their customers,partners and providers. The cloud computing includes vendors,partners,and business leaders as the three major contributors. Now we will see some important questions and answers

1) What is Cloud?

Ans: A cloud is a combination of hardware,software,storage,services and interfaces that helps in delivering computing as a service.It has broadly three users which are end user,business management user,and cloud service provider. The end user is the one who uses the services provided b the cloud. The business management user in the cloud takes the responsibility of the data and services provided by the cloud. Finally the cloud service provider is the one who takes care or is responsible for the maintenance of the IT assets of the cloud. The cloud acts as a common center for its users to fulfill their computing needs.

2) What is Cloud Computing?

Ans: The Cloud Computing is the computing which is completely based on the internet.It uses the internet and remote servers to maintain data and applications. A simple example for Cloud computing is Gmail and Yahoo etc...

3) Why Cloud Computing is Important?

Ans: There are many applications of Cloud Computing,for both developers and end users. For developers,cloud computing provides increased amount of storage and processing power to run the applications they develop. Cloud computing also enables new ways to access information,process and analyze data,and connect people and resources from any location anywhere in the world.

For end users,cloud computing offers all those benefits and more. A person using a web-based application isn't physically bound to a single PC,location,or network. His applications and documents can be accessed wherever he is,whenever he wants.No fear of losing data if a computer crashes.Documents hosted in the cloud always exist,no matter what happens to the user's machine. It is a whole new world of collaborative computing all enabled by the notion of cloud computing.

Cloud computing does all this at lower costs because the cloud enables more efficient sharing of resources than does traditional network computing.Cloud infrastructure can be located anywhere,including and especially areas with lower real estate and electricity costs.

4) What are the basic characteristics of cloud computing?

Ans: There are four characteristics of cloud computing as follows:

Elasticity and scalability
Self-service provisioning and automatic de-provisioning
Standardized interfaces
Billing self-service based usage model

5) What is Cloud service?

Ans: A cloud service is a service that is used to build cloud applications. This service provides the facility of using the cloud applications.This service provides the facility of using the cloud application without installing it on the computer. It reduces the maintenance and support of the application as compared to those applications that are not developed of users can use the application from the cloud service which may be public or private application

6) What are the features of Cloud Services?

Ans: The following are the some important features. They are

Accessing and managing the commercial software
Centralizing the activities of management of software in the web environment
Developing applications that are capable of managing several clients
Centralizing the updating feature of software that eliminates the need of downloading the upgrades.

7) What are the advantages of Cloud Service?

Ans: The following are some of the advantages of Cloud service: They are

Helps in the utilization of investment in the corporate sector and therefore,is cost saving.
Helps in the developing scalable and robust applications. Previously, the scaling took months,but now,scaling takes less time
Helps in saving time in terms of deployment and maintenance

8) What are the disadvantage of Cloud Computing?

Ans: The following are the some of the disadvantages of Cloud Computing: They are

Requires a constant internet connection
Doesn't work well with low speed Connections
Can be slow
Features might be limited
Stored data might not be secure
If the cloud loses the data,you are screwed

9) How many types of Cloud Services?

Ans: A cloud Service is any resource that is provided over the internet. The most common cloud service resources are.

Software as a Service(SaaS)

Platform as a Service(PaaS)

Infrastructure as a Service(IaaS)

10) How many types of deployment models are used in Cloud?

Ans: There are 4 types of deployment models are used in Cloud:

1)public cloud
2)private cloud
3)Community cloud
4)Hybrid Cloud

11) Why does the organization need to manage the workloads?

Ans: The workload can be defined as an independent service or a set of code that can be executed.
The organization manages workloads because of the following reasons:

To know how their applications are running
To know what functions they are performing
To know the charges of the individual department according to the use of the service

Compute
storage
Management

13) Explain Public and private cloud?

Ans: The public cloud(or external cloud) is freely available for access. You can use a public cloud to collect data of the purchasing of items from a web site on the internet. You can also use public cloud for the reasons which are given as follows:

Helps when an application is to be used by a large number of people,such as an e-mail application on the internet.
Helps when you want to test the application and also needs to develop the application code
Helps when you want to implement the security for the application
Helps when you want to increase the computing capacity
Helps when you are developing the project on an ad-hoc basis by using PaaS

The Private cloud allows the usage of services by a single client on a private network. The benefits of this model are data security,corporate governance,and reliability concerns. It offers a well managed environment. It provides capability to internal users allows provision of services.

Tips to crack Toughest Interview

noreply@blogger.com (learnprogramingbyluckysir) — Sat, 18 Feb 2017 08:51:00 +0000

In this article we will know some important tips to crack toughest interviews. These tips useful for all either IT or NON-IT. For any given vacancy,at least hundreds,if not thousands of candidates apply for the job. It takes only a few seconds for interviewer to reject you. It is important to succinctly outline your career objective,work experience,projects,training's, personal strengths and so on.

The following steps help you to crack toughest interview:

Evaluate the nature of the question:

Evaluate whether the question demands a factual answer and is meant to test your general knowledge and awareness. A factual questions like - who developed Java? This type of question demands correct answer.

However, a subjective one, like what are your thoughts "whether tablets replace text books?". In this type of questions,give a balanced answer by including as many perspectives as one can.

My conclusion is first understand the question what kind of answer interviewer expecting. In the case of factual questions,if you do not know the answer it is better to accept your ignorance and say: I'm sorry i do not know the answer.In case of subjective questions,give a balanced answer by including as many perspective as one can.

Your answer reflects who you are:

Interviewers ask tricky questions just so that they could gauge the candidate's personality.

For example, a question like - Do you think it was right on the part of our company to introduce the new employee policy?

If you are going to consciously make an attempt to sound positive or agreeable just so that the company hiring you will consider you application,you could be mistaken.

It is important to be honest and at the same time,sound relevant and important.

You could say- I think what the company did was right. But if i were in your place, I would..depending on what you think is right.

Stay calm,Think:

When faced with a tough interview or a tough question,it is important to stay calm.

Sometimes the questions is just to test the ability of the candidate to handle pressure and difficult situations.

Under pressure,one must not say anything, that could betray anxiety,nervousness,anger,
thoughtlesseness, biases and such other negative emotions.

Difficult situations are the true test of one's abilities. One must view these as opportunities and not threats.

Your positive attitude,confidence and presence of mind will alone help you cruise through a tough interview.

What is C Language

noreply@blogger.com (learnprogramingbyluckysir) — Wed, 15 Feb 2017 01:16:00 +0000

In this article we will learn the introduction of C programming Language. This is basic Programming Language who want become Programming Developer then he/she should learn C programming Language. C is a programming language developed at AT & T’s BellLaboratories of USA in 1972. It was designed and written by a man named Dennis Ritchie.

Ritchie seems to have been rather surprised that so many programmers preferred C to older languages like FORTRAN or PL/I, or the newer ones like Pascal and APL. But, that's what happened. Possibly why C seems so popular is because it is reliable, simple and easy to use. Moreover, in an industry where newer languages, tools and technologies emerge and vanish day in and day out, a language that has survived for more than 3 decades has to be really good.

C has been already superceded by languages like C++, C# and Java, so why bother to
learn C Language.Though many C++ and Java based programming tools and frameworks have evolved over the years the importance of C is still unchallenged because knowingly or unknowingly while using these frameworks and tools you would be still required to use the core C language elements—another good reason why one should learn C before C++, C# or Java.

Major parts of popular operating systems like Windows, UNIX, Linux is still written in C. This is because even today when it comes to performance (speed of execution) nothing beats C

Mobile devices like cellular phones and palmtops are becoming increasingly popular. Also, common consumer devices like microwave oven, washing machines and digital cameras are getting smarter by the day. This smartness comes from a microprocessor, an operating system and a program embedded in this devices. These programs not only have to run fast but also have to work in limited amount of memory. No wonder that such programs are written in C

You must have seen several professional 3D computer games where the user navigates some object, like say a spaceship and fires bullets at the invaders. The essence of all such games is speed. Needless to say, such games won't become popular if they takes a long time to move the spaceship or to fire a bullet. To match the expectations of the player the game has to react fast to the user inputs. This is where C language scores over other languages. Many popular gaming frameworks have been built using C language

At times one is required to very closely interact with the hardware devices. Since C provides several language elements that make this interaction feasible without compromising the performance it is the preferred choice of the programmer.

I hope that these are very convincing reasons why one should adopt C as the first and the very important step in your quest for learning programming languages

what is Hacking

noreply@blogger.com (learnprogramingbyluckysir) — Mon, 13 Feb 2017 08:48:00 +0000

In this post we will discuss about Hacking and how hackers employ a variety of techniques for hacking. Now a days, data networks became by far the most common target of hackers and hacking.

In computer networking,hacking is any technical effort to manipulate the normal behavior of network. The term "hacking" historically referred to constructive,clever technical work that was not necessarily related to computer systems.Now a days,hacking and hackers are most commonly associated with malicious programming attacks on the internet and other networks.

Hacking is unauthorized intrusion into a computer or a network. The person engaged in hacking activities is generally referred to as a hacker. This hacker may alter system or security features to accomplish a goal that differs from the original purpose.

Hackers employ a variety of techniques for hacking: They are

password cracking: The process of recovering passwords from data stored or transmitted by computer systems
Vulnerability scanner: Checks computers on networks for known weaknesses
Packet Sniffer: applications that capture data packets in order to view data and passwords in transit over networks.
Trojan horse: Serves as a back door in a computer system to allow an intruder to gain access to the system later
Viruses: self-replicating programs that spread by inserting copies of the same program into other executable code files or documents
Key loggers: This a tool designed to record every keystroke on the affected machine for later retrieval.
Root kit: It represents a set of programs which work to subvert control of an OS from legitimate operators.

Common networking Hacking Techniques:

Hacking on computer networks is often done through scripts and other network software. These specially designed software programs generally manipulate data passing through a network connection in ways designed to obtain more information about how the target system works. More advanced hackers may study and modify these scripts to develop new methods. A few highly skilled hackers work for commercial firms,hired to protect that company's software and data from outside hacking.

Cracking techniques on networks include creating worms,initiating denial of service(Dos)attacks,or in establishing unauthorized remote access connections to a device.

Requirements for effective hacking the combination of technical skills and personality traits:

Ability to work with numbers and a background in mathematics. Hacking often requires sorting through large amounts of data,code and computer algorithms
Memory recall and logical reasoning,Hacking involves assembling small facts and details into a plan of attack based on the logic of how computer systems work.
patience.Hacks tend to get very complex and require large amounts of time to plan and execute.

Operating System Interview Questions

noreply@blogger.com (learnprogramingbyluckysir) — Sun, 12 Feb 2017 15:36:00 +0000

2) What are the different Operating Systems?

Ans: There are different types OS they are

1) Multi-programming OS
2) Distributed OS
3)Batched OS
4)Time-sharing OS
5)Real-time OS

3) Why paging is used in OS?

Ans: Paging is solution to external fragmentation problem which is to permit the logical address space of a process to be noncontinuous,thus allowing a process to be allocating physical memory wherever the latter is available.

4) What is the state of the processor,when a process is waiting for some event to occur?

Ans: The state of the processor is : Waiting state

5) What is Virtual Memory?

Ans: Virtual Memory is hardware technique where the system appears to have more memory that it actually does. This is done by time-sharing ,the physical memory and storage parts of the memory one disk when they are not actively being used.

6) What is fragmentation?

Ans: Fragmentation occurs in a dynamic memory allocation system when many of the free blocks are too small to satisfy any request.

7) What is the cause of thrashing? How does the system detect thrashing?

Ans: Once it detects thrashing,what can the system do to eliminate this problem? Thrashing is caused by under allocation of the minimum number of pages required by a process,forcing it to continuously page fault. The system can detect thrashing by evaluating the level of CPU utilization as compared to the level of multi programming. It can be eliminated by reducing the level of multi programming.

8) While running DOS on PC,which command would be used to duplicate the entire diskette?

Ans: This command will be use to duplicate the entire diskette diskcopy.

9) What is cache-memory?

Ans: Cache memory is random access memory(RAM) that a computer microprocessor can access more quickly that it can access regular RAM. As the microprocessor process data,it looks first in the cache memory and if if finds the data there(from the previous reading of data). It does not have to do the more time-consuming reading of data from larger memory.

10) What is Kernal?

Ans: Kernal is the core and essential part of computer operating system that provides basic services for all parts of OS.

11) What is a process?

Ans: A program in execution is called a process or it may be called unit of work. A process needs some system resources as CPU time,memory,files and I/O devices to accomplish the task.

12) What is semaphore?

Ans: Semaphore is a variable,whose status reports common resources,Semaphore is of two types one is Binary semaphore and other is Counting semaphore.

13) What is deadlock?

Ans: Deadlock is a situation or condition where two processes are waiting for each other to complete so that they can start. This result both the processes to hang

14) What are system calls?

Ans: System calls provide the interface between process and the OS. System calls for modern Microsoft windows platforms are part of the win 32 API. Which is available for all the compilers written for Microsoft Windows.

15) What are the states of Process?

Ans: There are 5 states of Process. They are

1) NEW
2) Running
3) Waiting
4) Ready
5) Terminated
