System – It may be Desktop, Mobile etc. but system must have sufficient storage/memory to run the browser.
Browser – A browser is software which is necessary in order to view any Web pages.
Internet Connection – You must have Internet connection.
Internet Service Provider – The companies which provide access to Internet are known as Internet Service Provider.

Types of Internet Connection:-

You can connect to Internet in three different ways they are:-

Dedicated Internet Connection
Dial-up Internet Connection
Broadband Internet connection

What is Web?

The Web is similar to library it consist billions of pages of text, pictures, videos, animation, music etc. These pages are called Web pages which are stored on different computers connected to Internet.

Basically a collection of all these Web pages are known as Web.

Many people get confused between Internet and World Wide Web. They think that both are same but actually it’s not the Internet is a huge network and World Wide Web or the Web is a part of internet.

Services of Web:-

Services of World Wide Web are:-

E-mail – It is the most commonly used Internet service in which you can send and receive messages from all over the world.

Networking Overview

What is Network?

A Network is formed when two computers or more than two computers are connected with each other. Network allows computers to communicate with each other to share resources and information with the other users in the network.

Components of Network:-

In communication Network consist three components. They are:

The sender – Who transfers or shares information.
The receiver – Who accepts the transferred or shared information.
The medium – Which transmit the information.

Computer Networks also consists set of components. They are:

Server – A server is a computer that provides resources or services to the other computer connected to a network.
Workstation – A workstation is a computer on a Network that can utilize the shared resources.
Communication Channel – It is the connection between computers on Network. Like satellites is example of communication channel.
Network Interface Unit (NIU) – It enables communication between systems that use different communication forms.

Types of Networks:-

Depending on the geographic location it can be classified as:

Local Area Network (LAN)
Metropolitan Area Networks (MAN)
Wide Area Network (WAN)

Local Area Network:-

If a network is confined to a single location it is called Local Area Network.

Example: A set of computers within a classroom or office.

Wide Area Network:-

When a Network is located over wide areas such as countries, states, cities etc. it is called Wide Area Network.

Example: The computers connected to network in different branches of globalized companies, Internet.

Metropolitan Area Networks:-

A Metropolitan Area Networks connects computers distributed across multiple buildings on a school campus.

Example: Computers connected to network in all the branches of school within a city.

Classification of networks based on components:-

Server-based Networks
Peer-to-Peer Networks

Server-based Networks:-

In server-based-network one computer act as server and other computers act as client. A server is computer that provides resources as per the request of client.

Example: file services, Web services etc.

Classification of Servers:-

Dedicated servers – It is a computer whose only task is to service clients. These servers are not used as workstations.
Non-Dedicated servers – These servers are used as workstations.

Peer-to-Peer Networks:-

In this network each computer acts as both server and client. Peer-to-Peer networks are also called workgroups. These networks do not have any dedicated servers. In this network the efficiency of the network decreases as the number of workstation increases.

Advantages of Network:-

Network not only connects computers it also connects people and bring them closer from all over the world. Social media is good example of communication.

Pythonpedia

Advantages of Computer Network:-

Some advantages of Computer Networks are:

Managing resources – All the computers connected to network can share resources to all the Users.
Managing infrastructure costs – Sharing resources to all over the computer networks reduces the need to procure expensive resources for individual computers in an organization.
Sharing files and programs – You can share your files to network so that Users connected to network can take benefits of them.
Communicating with other Users – You can communicate with the other users all over the world by sending and receiving messages. This method of communication saves your time because you don’t need to meet them personally to communicate.

Computer Security

Threats of Computer Security:-

A threat is a potential violation of security. When a threat is actually executed it becomes attack. And those who do such action or make them to be happen are called attackers.

Some common computer threats that users faces every day are:

Viruses
Adware
Spyware
Spamming
PC Intrusion
Phishing and Pharming

The Computer Viruses:-

The viruses are malicious codes or program that cause damage to Data and files on a computer system. These viruses can attack on any part of system software such as operating system, files, boot block, systems areas and application macros etc.

Two similar programs also cause virus like effects are:

Worms – A worms are a self-replicating program which eats up the entire disk space or memory. It creates copies of files until the disk space is fully filled.
Trojan Horses – A Trojan Horses are a program that appears harmless but actually it’s very harmful. The harm it causes is deleting the files or damaging them.

Damage caused by Viruses to the System:-

Viruses can harm the system if it is not checked:

Damage or Delete files – Some viruses may delete or damage random documents or specific files that are crucial to your operating system.
Slow down your computer – Viruses can run in the background without being seen or knowing you which makes your computer work extremely slow.
Invade your email program – Some forms of viruses may wreak even more havoc by spreading themselves to the contacts in your address book.

Spyware:-

It is software which is installed on your computer to spy on your activities and report this data to people willing to pay for it. It tracks user behavior and reports information back to the central source. It may be legal or illegal.

This software mostly gets installed on your computer or system without your consent.

Damage caused by Spyware to the System:-

It can act like peeping tom or a geeky thief for example it can:

Compromises your Data, computing habits and identity – It can monitor information such as what websites you visit or record your keystrokes and then send them cyber thief.

Slows down your system – It can rob your system speed and internet access efficiency. When you try to download large files, watch online content etc.

Adware:-

These are the programs that deliver unwanted ads to your system like Pop-Ups. They consume your network bandwidth. It is similar to spyware but it may be installed with your consent. So it is advised that you should read installation agreements thoroughly every time before installing software.

Damage caused by Adware to the System:-

Some damage caused by Adware’s are:

Adware tracks information – It tracks your computing habits to produce targeted advertising on your computer screen.
Displays arrays of annoying advertising – When infected with adware you will likely see frequent pop-up ads appear all the time.
Slows down your Pc – It is common when any virus attacks your system.

Spamming:-

It refers to the sending of bulk mail by an identified or unidentified source. In non-malicious form bulk advertising mail is sent too many accounts. In malicious form the attackers keeps on sending bulk mail until the mail server runs out of disk space.

Damage caused by Spamming to the System:-

Effects caused by spamming:

Spams reduces productivity
Spam eats up your time
Spam can lead to worse things

PC Intrusion:-

Every system connected to the Internet is potentially targeted by hackers. PC Intrusion can occur in any of the following form:

Sweeper Attack – This is another malicious program used by hackers. It deletes all Data from your system.
Denial of Services – This type of attack eats up all the resources of a system and the system or application comes to halt.
Password Guessing – Mostly hackers crack or guess password of system accounts and gain entry into remote computer systems.

Eavesdropping:-

Unauthorized monitoring of other people’s communications is called Eavesdropping. Eavesdropping is a passive attack in which an attacker’s gains access to the communication medium through which some communication is taking place and then listens to the communication and gets information about the content of the message.

Eavesdropping can be carried out through all communication devices and media like emails, instant messaging, Internet services etc.

Phishing and Pharming:-

Phishing – It is the criminally fraudulent process of attempting to acquire sensitive information such as usernames, passwords, credit card information, account Data etc.

Pharming – It is an attack in which a hacker attempts to redirect website traffic to another, bogus website. Even if the URL is entered correctly it can still be redirected to a fake website.

IP Address – IP Address is a unique address of your device when you connect to Internet.
Cookies and Tracking Scripts – Cookies are small pieces of information websites can store4 in your browser. It can be First party cookies, Third party cookies.
HTTP Referrer – When you click the link your browser loads the web page linked to it and tells the website where you came from.
Super Cookies – Super cookies are also cookies but these are persistent cookies i.e. they come back even after you delete them.
User Agent – This tells websites your browser and operating system, providing another piece of data that can be stored and used to target ads.

Private Browsing & Anonymous Browsing:-

Pythonpedia

Anonymous Browsing:-

Anonymous browsers allow users to view websites without revealing any personal information the user like IP Address, machine type, location etc. An anonymous browser lets user’s access websites anonymously.

Private Browsing:-

There are many others ways to use the Internet without revealing your search history and sharing your data. These are:

Incognito browsing
Proxy
Virtual Private Network (VPN)

What is Confidentiality of Information?

Internet is a public platform. The sites you visit, the things you search on it, the post that you put on social networking sites are visible to public means all. But there must be some details like bank details, your mails etc. which you don’t want to make public. Therefore you want to make them confidential. Confidentiality of information ensures that only authorized users get access to sensitive and protected Data.

Some practices to ensure Confidentiality of Information:-

Best practices used to ensure confidentiality are as follows:

Use firewall wherever possible
Control browsers setting to block tracking
Browse privately wherever possible
Be careful while posting on Internet
Ensure safe sites while entering crucial information
Carefully handle emails
Do not give sensitive information on wireless networks
Avoid using public computers:
- Browse privately
- Do not save your login details
- Never save passwords while using public computer
- Disable feature that store passwords
- Properly logout before leaving public computer
- Clear history and cookies

What is Programming Methodology?

2018-08-25T12:45:00.002+05:30

Pythonpedia

What is Programming Methodology?

Introduction:-

Computerized information systems are developed to provide computer solutions to user problems. Lawrence Peter has started “Software design technology is a system not a secret”. A systematic approach in software design should be adopted to develop an acceptable and efficient solution.

The software designing involves mainly two things that is program structure and program representation.

Stylistic Guidelines:-

Developing good programs is a skill and writing good program is a quality habit. This good habit can be developed by following the guidelines.

Modular Approach to Programming – Always break a big program into smaller subcomponents called modules and this is called the Modular Approach to Programming.
Meaningful Names for Identifiers – Identifiers identify different parts of a C++ program or script.
Use Comments and Indentation – Comments play a very important role in programming as they provide internal documentation of a program. And Indentation makes the program clear and readable.
Statement Formatting Style – C++ is one of those languages which provide use of free formatting style.

Types of Errors:-

Compile Time Errors
Run Time Errors
Logical Errors

Problem Solving Methodology and Techniques:-

Understand the program well
Analyze the problem
Think the possible solutions
Follow Modular approach while designing most appropriate solutions
Identify operations for solution
Code program using appropriate control structures
Test and Debug your program
Complete your documentation
Implement your code
Maintain your program

Documentation:-

Documentation must describe the ‘who’, ‘what’, ‘when’, ‘where’, ‘how’ etc. for each system application.

Documentation refers to written descriptions, specification, design, code and external to a program which make program more understandable.

Program Maintenance:-

Program maintenance refers to the modification of a program, after it has been completed, in order to take care of errors that come up.

There are four kinds of maintenance:

Corrective Maintenance
Adaptive Maintenance
Preventive Maintenance
Perfective Maintenance

Computer Overview

Introduction:-

Computers have made great inroads in our everyday life and thinking. They are put to use for all sorts of application ranging from complex calculation in the field or frontline research, engineering simulations down to teaching, printing books and recreational games. The ease with which computers scan process data, store and retrieve it painlessly has made them inevitable in office and business environments. The areas of applications of computers are confined only by limitations on human creativity and imagination. In fact, any task that can be carried out systematically can be performed by computer. Therefore, it is essential for every educated person today to know about a computer.

What is Computer?

Pythonpedia

A computer is an electronic device that can perform a variety of operations in accordance to a set of instructions called program.

Computers can access and process data millions of times faster than humans can. A computer can store data and information in its memory, process them and produce the desired results. Computers can do a lot of different tasks such as weather forecasting, playing games, error detection, railway reservation etc.

A computer is essentially as a data processor. The terms data and information are very commonly used. Data are raw facts whereas Information is meaningful data.

Functional component of a Computer:-

Since a computer follows input-process-output cycle. The first stage is performed in computer by input unit; second stage is performed by its central processing unit and the third stage is stage performed by output unit.

Hardware and Software:-

Hardware represents the physical and tangible components of the computer i.e. the components that can be seen and touched. Or we can say that collectively, the electronic, electrical and mechanical equipment that makes up a computer is called computer. Input devices, Output devices, CPU, hard disk etc. are all examples of computer hardware.

Software represents the set of programs that govern the operation of a computer system and make the hard ware run.

Software can be classified broadly into three categories:

Operating System
Language Processor
Application Software

Together operating system and language processor are known as system software.

Operating System:-

Pythonpedia

An operating system is a program which acts as an interface between a user and the hardware (i.e. all computer resources) and controls all other components of the computer system.

Operating system is just like our secretary. As the boss gives orders to his secretary and secretary does all the work for his boss. The secretary himself decides: How to do?; What to do?;When to do?;etc. Same way we pass our orders and operating system does it for us.

Example: Windows, Linux, UNIX etc.

Language Processors:-

The system programs which convert High-level language into Low-level language are known as Language processors.

The language processors are given below:

Assembler.
Interpreter.
Compiler.

Strengths and Weaknesses of a Computer:-

The strengths of a Computer are:

Speed
High Storage Capacity
Accuracy
Reliability
Versatility

The weaknesses of a Computer are:

Lack of Decision Making Power
IQ Zero

The generation of Computers:-

First Generation (1940-1956) – Vacuum Tubes
Second Generation (1956-1963) – Transistors
Third Generation (1964-1971) – Integrated Circuits
Fourth Generation (1971-Present) – Microprocessors
Fifth Generation (Present-Beyond) – Artificial Intelligence

Evolution of Storage technologies:-

The electronic revolution started from 18^th-19^th century and changed the human life forever. The associated data storage technologies also evolved with computer evolution. Let us how these storage technologies evolved over time.

Machine-Readable Punched Card (1890)
Magnetic Drum (1932)
Magnetic Tape (1951)
Hard Disk Drive (1958)
Floppy Disk (1969)
Optical Storage Media – CD (1980s), DVDs (1990s)
Flash Drive (1998)
Blue-Ray Discs (2000)
The Cloud (21^st century)

Evolution of Display technologies:-

CRT-Cathode Ray Tube (1897)
LCD-Liquid Crystal Display (1963)
Plasma Monitors (1964)
Touchscreen Monitors (1965)
OLED-Organic Light Emitting Display (1987)

Evolution of Programming language:-

1^st Generation Programming Language (1GL)
2^ndGeneration Programming Language (2GL)
3^rdGeneration Programming Language (3GL)
4^th Generation Programming Language (4GLs)
5^th Generation Programming Language (5GLs)

Evolution of Software Application:-

Command Line Programs (1980s) –The first generation software applications included compilers, device-drivers etc.
Desktop Applications (1990s) – With the popularity of graphical interface, GUI based desktop applications of multiple types and forms were released: Office Applications, Audio and Video players, Utility programs, Browsers etc.
Web Applications (21^st Century) – Most popular web applications include Email clients like Gmail etc.; Social networking platforms like Facebook, Twitter, Instagram, Pinterest, Quora etc.; VoIP Programs like Skype etc. and many more.
Mobile Applications (21^st Century) – The popular Mobile Application development platforms are iOS, Android, Windows, which are also the most popular mobile operating systems.

Types of Computers:-

Purpose Wise

Special purpose Computers – A special purpose computer is the one that is designed to perform a specific task.
General purpose Computers – A general purpose computer is the one that can work on different types of programs input to it and thus be used in countless applications.

Principle of Operation Wise

Analog Computers – These computer types work with continuous physical quantities such as voltage, current, temperature etc. But their accuracy is poor. Analog computers are mostly used in engineering and scientific applications. An electronic weighing scale is an example of an analog computer.
Digital Computers – These computer types work with discontinuous data converted into binary form i.e. digits 0 and 1 and all operations are carried out on these digits at extremely fast rates. Computers are much faster than analog computers and far more accurate. These computers are used for business and scientific applications.
Hybrid Computers – Hybrid computers utilize the best qualities of both the digital and analog computers. In these computers some calculations take place in analog manner and rest of them take place in digital manner. Hybrid computers are best used in hospitals to monitor patient’s vital signs. Hybrid computers are also used for weather forecasting.

Types of Digital Computers:-

Embedded Computers – These computers are in the form of tiny chips embedded within the circuit of appliances such as televisions, washing machines and wrist watch etc.
Personal Computers (PCs) – These are mainly used in offices, homes, schools, shops, stores etc. IBM PCs, Apple Mac, IBM PS/2 are some popular computers of this range.
Minicomputers – Minicomputers are mainly multiusers system where many users simultaneously work on the system. Examples are PDP-11, VAX and 7500 MAGNUM etc.
Mainframe Computers – These computers are designed to handle huge volumes of data and information. These are very large and expensive computers have great processing speed and very large storage capacity and memory. Examples are ICL 39, CDC 6600, VAX 8842, IBM 3090/600 and IBM 4381.
Super Computers – These computers are the most powerful computers among digital computers. These consist of several processors running together thereby making them immensely faster and powerful. Examples are CRAY X-MP-14, CDC-205, ETA GF-10, FUJITSU VP-400, NEC SX-2, PARAM and PACE.

What is Python? And its uses!

2018-08-15T13:43:00.000+05:30

Pythonpedia

What is Python? And its uses!

Python :-

Generally in Technical terms. Python is an Interpreted, Object-oriented, High-level programming language for general purpose programming with dynamic semantics. The founder or the creator of Python is Guido van Rossum. Python was first released in 1991. Python has a design philosophy that emphasizes the code readability, notably using significant whitespace. It provides construct that enable or create a platform for us to do clear programming on both small & large scale. Python is simple & easy to learn syntax emphasizes readability and which reduces the cost of program maintenance. Often programmers fall in love with Python because of its increased productivity. There is no compilation step which save’s time also the edit-test-debug cycle is comparatively fast. A source level debugger allows inspection of local and global variables, setting breakpoints and so on.

History:-

Actually Python was conceived in late 1980s, and its implementation began in December 1989 by the creator Guido van Rossum at Centrum Wiskunde and Informatica which is a National Research Institute for Mathematics. Python got its name from a BBC Comedy series from seventies – “Monty Python’s Flying Circus”. Van Rossum was a Python’s principal author. His continuing role in Python’s development is reflected in the title given to him by Python community and the title is “Benevolent Dictator For Life”.

The language’s core philosophy is summarized in document “The Zen of Python” which includes aphorisms such as

Simple is better than complex
Complex is better than complicated
Explicit is better than implicit
Beautiful is better than ugly
Readability counts

Rather than using all of its function built in its core, Python is designed highly extensible.

Features of Python:-

Easy to use – Due to simple syntax rule
Interpreted language – Code execution & interpretation line by line
Cross-platform language – It can run on windows, Linux, UNIX, Macintosh etc. equally
Expressive language – Les code to be written as it itself express the purpose of code
Completeness – Support wide range of library
Free & Open Source – Can be downloaded freely and source can be modify for improvement
Dynamic type system and automatic memory management.
It supports multiple programming paradigms,
Including imperative, functional and procedural, and has a large and comprehensive standard library.

Shortcomings of Python:-

Lesser libraries – as compared to other Programming languages like C++, java, .net etc.
Slow language – as it is interpreted languages, it executes the program slowly.
Weak on Type-binding – It not pin point on use of a single variable for different data type.

Some of the features which make Python so popular are as follows:-

It is a general purpose programming language which can be used for both scientific and non-scientific programming.
It is a platform independent programming language.
It is a very simple high level language with vast library of add-on modules.
It is excellent for beginners as the language is interpreted, hence gives immediate results.
The programs written in Python are easily readable and understandable.
It is suitable as an extension language for customizable applications.
It is easy to learn and use.

The language Python is used by companies in real revenue generating products, such as:-

In operations of Google search engine, YouTube, etc.
Bit Torrent peer to peer file sharing is written using Python
Intel, Cisco, HP, IBM, etc. use Python for hardware testing.
Maya provides a Python scripting API
I–Robot uses Python to develop commercial Robot.
NASA and others use Python for their scientific programming task.

Three packages of Python Language:-

NumPy. It provides some advance math functionalities to python.
pyGtk. Another python GUI library. It is the same library in which the famous Bit torrent client is created.
Pandas are a library written for the Python programming language for data manipulation and analysis.
