Introduction to the operating system

Even though the CPU is high-speed, it can do simple operations like adding to me

multiplying two numbers, etc., but not much more. Even simple activities like input or output of a name or converting a string of characters to uppercase or displaying an image on the screen must be built on top of these essential capabilities by writing a series of basic instructions

Also, the Computer has a large number of peripheral devices like keyboard, mouse, monitor, hard

disk, optical disk, printers, and other removable devices. Operating these devices require ting

long and complicated series of basic instructions

A modern computer system has a variety of resources like CPU, memory, secondary storage,

network, peripheral devices, etc. Multiple programs access these. Running concurrently

sometimes on behalf of different users with a different set of access rights. There needs to

be some "authority that regulates and mediates access to these resources.

A computer without any software for the above operations is a practically unusable device, because

it may not even have the primary user interface to interact with the user to provide a consistent

experience to the user, there needs to be a common framework for the standard mail. Computer

interactions. To strengthen the Computer, such a structure should also provide several types

of abstractions and metaphors. A file system metaphor is one such example that has discussed.

Thus an operating system exists to satisfy all these needs. Because it controls the whole system

it is always the first program to be started when the computer system is turned on.

What is an Operating System

An operating system is a controller, resource allocation standard services provider for a computer system. Like the government, it performs these functions to ensure smooth and mostly trouble-free

operation of the Computer.

The Startup Process of a Computer

When the Computer is supplied power and turned on the CPU takes control of the whole system

It initializes itself by bringing all its subcomponents in a known and ready-to-use state. Now it is like vehicle whose ignition has turned on and is ready to be driven" But where is the

driver" (the instructions to be executed by the CPU)? The Computer hs a type of permanent

memory called ROM (on personal computers, this is often called ROM BIOS (Basic Input Output

System or simply BIOS) that contains an initial program. This initial program, called POSLE(Power

On Self Test), performs a necessary check on all other components and peripheral devices in the Computer

and initializes them, so they are ready for us. Hence the next step in this sequence is to locate operating systems on the attached storage devices select the one to be loaded in many memories,

load it and start executing it. Once the operating system starts its execution, it takes control of

the entire computer system. This whole process is called "booting" the Computer to a particular

operating system.

Functions of an Operating System

An operating system (OS) performs a different set of essential functions as mentioned below

Providing hardware access as a basic service.

Controlling, Regulating and Supervising resources in the Computer

Handling Multiprocessor Systems

Starting and Stopping Program Execution

Controlling Access to the Memory

Serving Multiple Users at the Same Time

L Providing Security

Providing Other Common Services

Providing Hardware Access is a Common Service

In the earliest days of computing, each computer program would come with a set of instructions

To handle a fixed set of devices like printers, etc. If a new kind of printer added to a computer, it became necessary to add the instructions required to handle the new printer to every

Program to execute on that Computer. With the rapid increase in the number of devices and

device manufacturers as well as the number of applications to be run, this approach soon became

Infeasible. Thas, the operating systems started providing a simple service of handling the hardware

Devices. The code instructions) to control particular devices would be part of the operating system, and the operating system would provide access to these devices to individual programs as a standard

Service. When a new machine came into use, the original instructions needed to operate it would only

have to add to the operating system and thousands of individual programs spared of any the modification.

Controlling, Regulating and Supervising Resources in the Computer

Modem computers are far more potent than their humble predecessors and have access to at

Higher amounts of resources like processing power, main memory, storage, etc. As a result, they

Are now capable of running not just one program at a time, but many applications at a time. This ability is called multiprogramming. CreatesComputer a new message, as well. When only one program is

Running at a time, it has full access to all the resources, and there is my harm in it. But what

happens when many programs are running at a time and we programs start printing to the same

the printer at the same time or start writing to the same location of the same storage medium at the

the same time Obviously, access to shared resources must be controlled in such an environment

The operating system plays the crucial role of resource controller, regulator, and supervisor for

all hardware resources.

A computer system may have more than one CPU (processor) as well. A computer system

having more than one processor is known as a multiprocessor system. Operating systems for

ch multiprocessor systems are con

more complex than those designed only for single-processor systems. Managing which processor to use for execution is the job of the operating system.

Starting and Stopping Program Execution

When it begins initially, it runs only the operating system. The operating system takes

complete control of the computer system. It also runs a unique program called the shell. The shell

Duct a user interface (UD) to work. The user interface allows the user to indicate

What to do. It accepts requests for performing operations from the user (these requests

may be in the form of typing a command or clicking with a mouse, or touching on a touch panel, etc.) and initiates actions to fulfill those requests. If it is required to start a program to fulfill

requests, the operating system to do so. As the operating system has full control over

the network, only the operating system can start or stop programs.

Controlling Access to the Memory

The main memory is an essential resource for the computer system because it is the only large

scale form of mind that can match the speed of the CPU and can be directly accessed by the

CPU. Any program to be run must be loaded into main memory and any non-trivial data set to

Be manipulated must also be in main memory for the manipulation to occur. Hence this resource must be used judiciously. As a result, access to the main memory is also under complete

Control of the operating system, just like access to other resources. A process needing to get or

release some amount of main memory must request the operating system to do so and no means

Is permitted to access memory not allocated to it by the operating system. This is known as

memory protection

Serving Multiple Users at the Same Time

An operating system may be designed for use by only one user at a time (a single user system)

By several users simultaneously a multiuser system). With a multiuser operating system. It is actually

possible to run the programs of many users on a single computer usually called server, with each

the user performing input/output through their terminal that may have keyboard, mouse, and monitor

This is useful when all users cannot be provided with the powerful computers they need (due to

the cost factor) and a single powerful computer must be shared among many of them.

A multiuser system also provides additional benefits of centralized management and resource

(e.g., file) sharing. Sometimes, a computer system in a faraway corner of the world can be accessed

remotely by users over the Internet. This enables traveling employees of large organizations to access

their computers from anywhere in the world for doing their work. It also allows the technical support

of the organization to access computers in different offices and to diagnose and solve their

problems without wasting time on physical travel. Some companies even provide their employees with the option to work from their home.

Providing Security

When multiple users accessing in c in the same computer system, the operating system must provide a level of isolation between there so that one er cannot disturb the work of another user

At the time where there we collaboration joint project, they may be able to

Mme resources Hence the operating system must provide a security mechanism that ensures that

all authorized use of the support is permitted, while all attempts at unauthorized we are strictly

Denied. Modern operating systems are designed to provide such security.

With the heavy we of computer networks and the Internet, it is possible to be and

A computer system remotely possibly from thousands of kilometers away. While this facility

a boon for organizations having multiple offices around the world or for employees like a pro

and managers who have to travel a lot and still need to do their office computer, it can be

for gaining unauthorized access to mee's computer Modern operating systems provide

some base mechanisms to protect against such hazards, though they may not be sufficient by

themselves.

Providing Other Common Service

Apart from the functionalities, operating systems also offer my current services to make the operation of the computer systems tier. Many of these services remain hidden from the

because other programs on the Computer follow them and not by the human users directly

Operating systems also often come with some companion programs (utilities or accessories) that are small and simple and EFL to most of the Computer

These include a service to explore the information read on the Computer all browser, text editor, calculator program to view and edit images, a program to play audio and video, a web browser for sure the Internet. All operating systems, except for the embedded systems

be provided at least one shell program to allow the user to interact with the computer system

Though these do not entail part of an operating system, most operating systems come with some

such as a bonus. Some operating systems, especially the free ones, come with

a comprehensive set of software ready for daily use in different age scenarios like one

educational Institutes and office.

Typical Components of an Operating System

In this section, while discussing the components typically associated with an operating system and

the full environment surrounding the operating system. Keep visiting our 3.1 while reading the

description. This guide provides a simplified layered view of the operation or the computer system

in the context of operating system study

The Device Driver

At the lowest is the raw hardware of the Computer As we have seen earlier, this Parton

called the "raw iron," Is an immensely powerful system, but has no clue with as to what to do. This

layer also comes from various staff devices requiring potentially different to operate. The device drivers are small programs that contain the instructions

necessary for using these devices. While many of them come bundled with the operating system

SOe may have to be installed separately from a disk or the Internet. They are loaded and

unloaded as and when needed by the kernel. The kernel uses them for operating and controlling

the hardware.

The Kernel

The kernel is the core component or the main program of the operating system. A traditional kernel performs all the critical functions of an operating system including detecting new hardware when attached and loading appropriate device drivers to access it, accessing and controlling all equipment devices through the device drivers), resource allocation and management, creating, stopping and managing program execution, scheduling program execution, providing CPU, 1/O and memory Protection. I/O management, memory management, security, etc. By some definitions, the kernel IS the operating system.

COMPUTER NETWORK

A computer network is a collection of computers and other external devices (such as printers and modems) connected utilizing communication links. The fundamental objective of a computer network is to facilitate the sharing of data and hardware resources among a wide range of users. The computers in a system can link through cables, telephone lines, radio waves. The complexity of a computer network may vary from just two computers connected to a network combining millions of computers totally across the globe.

NOTE; - This image is taken from this site I do not belong from this image.

When you connect your computer to a network via a cable means you become a network user and your computer becomes a workstation for sometimes called node) on the net. Your computer can access all its local resources such as local hard drives or printer. It can use the network resources, including printer, disk storage space. For example, you can print a document on the printer attached to some other

computer on the network.

Advantages of a Computer Network

A networked environment of computers has several advantages. Some of these give below: -

Speed- You can share and transfer files within a computer network very rapidly. It sure
times while maintaining the integrity of data.
Communication- A computer network facilitates communication via email
videoconferencing and instant messaging.
Information sharing- In a networked environment, the information can keep.
A single computer is known as the server. All the other computers in the network can access
the information stored on the server.
Resource sharing- The primary aim of networking is to share resources regardless of the
the physical location for better communication Resource sharing involves the sharing of
both the hardware and software resources among the multiple users connected to the
network.
Preservation of Information- It is easy to take a backup of data in a networked environment
rather than on several stand-alone computers.
Cost-effectiveness- Due to the interconnection of computers, it is easier to access and
transfer a large amount of data from a far distance in a cost-effective manner and a
short period.
Reliability- The backup facility in networking makes it a reliable model for communication.
And sharing files. In case one computer in a network fails, the data can access from other computers.

Disadvantages of a Computer Network

Some of the disadvantages of a computer network given below:-

Security- One of the significant drawbacks of computer networks is the security If
the proper network security check not performed, there is a possibility of the theft of
confidential and private data.
Dependency on the server- If the server breaks down the working of all the computers on the network disrupted, and the entire system becomes useless.
The rapid spread of computer virus- If any computer in the network gets affected by a computer virus, other computers can also be affected. There is a possibility that that virus can corrupt essential data.
Expensive- The setup cost of a computer network can be high, depending on the number
of computers to be connected.
Degraded performance- If the traffic of data increases on the network, the performance of
the system degrades if it not appropriately designed.

TYPES OF NETWORKS
Computer networks can be categorized based on their size, the distance they cover, and the
Links used for their interconnection. According to the physical distance, a computer network.
covers, it can categorize into four types, namely (MAN), (LAN), (WAN), (PAN), Personal Area Network, Local Area Network, Metropolitan Area Network, and Wide Area Network.
Personal Area Network (PAN)
A PAN is the least reasonable network signified for one person. It is used to interconnect individual devices such as a computer, laptop, mobile phone, tablet, or any other hand-held the method of an individual. The ways in a PAN are Printer linked together either using cables or wirelessly. In wired PAN, the devices communicate PDA through a USB cable. While in a wireless PAN, Bluetooth and infrared technologies used for Laptop communication. This network can cover an area Desktop of only a few meters (less than 10 meters).

Local Area Network (LAN)

A LAN is a network that reaches a comparatively small region such as an apartment. Generally, it comprises interconnected personal computers, which is capable of obtaining and giving data and devices such as (printers and scanners), anywhere on the LAN.
A LAN does not pass an area of two to three square kilometres. It may assist as few as two or three users up to hundreds of users. This networks are owned, controlled, and managed by a single person or an organization.
Metropolitan Area Network (MAN)
A MAN is a network that covers an area of a city. It is formed by connecting multiple LANS One or more organizations may own it. An example of a MAN is the cable TV networks that spread over a city. It is more efficient and provides a high-speed connection using fibre optic cables.
Wide Area Network (WAN)
AWAN is a network that spans a large geographical area such as several cities or even countries.
It connects different smaller networks, including LANs and MANs.
Computers in a WAN often connected through public networks such as telephone systems.
Sometimes, satellites also are wont to connect computers in a very WAN.
The Internet is associate degree example of a wide used WAN.

NETWORK ARCHITECTURE
Network architecture refers to the layout of a computer network that specifies how a computer network is configured to facilitate information exchange and resource sharing, The two major.
types of network architectures are a client-server and peer-to-peer network.
Client-Server Network
In a client-server network, many workstations (called clients) connected to a centralized
Bost computer is known as a server. To accomplish any task, the client requests a service like data retrieval from the server, and the server responds by providing the service. Also, assist clients, the server controls access to hardware, software, and another network resource.
Peer-to-Peer Network
A peer-to-peer network does not rely on a central server for communication. Instead, the
Computers having equal capacity and capability (called peers) are connected to Use the resources on the network. Each computer on a peer-to-peer network can act both as a server and a client.

INTERNET, INTRANET, AND EXTRANET

The Internet is the largest network that connects countless computers worldwide to share

iInformationand service. People all over the world and use the Internet for various purposes

like web send mails watch videos play online games and download data

Moreover, an intranet is a private computer network owned by a company or an organization and

access to its employee ft closely related to the Internet but has a protecting system

To prevent authorized access from external computer networks. Thus, it has a limited number of Bluetooth. It uses the Internet protocols, network connectivity, and telecommunication system to share part of the organization's information or operations with its employees.

An extranet is a computer network that allows outside users to have limited access to the part of the organization's data. These users include vendors, suppliers, or customers that may need to access the organization's data for some business purposes or customer services.

PROTOCOLS

The communication between computers is possible by using a protocol that offers a standard format. Another method for communication protocol is a formal set of rules and how computers exchange information over the network. There are a large number of contracts that can be used in a system, depending on the need they fulfil. Two of these discussed here: -

TCP/IP(Transmission Control Protocol/Internet Protocol) It the suite of communication

Protocols which used as a standard for transmitting data over networks. TCP/IP consists

of two contracts, namely, TCP and IP TCP is responsible for dividing the message or

file into small packets at the source computer that transmitted over the network Then

at the destination computer, it resembles the packages into the original word or file

On the other hand, the IP handles the address part of each packet so that it reaches the

right destination Any computer or a device which connected to the Internet must be

supported by TCP/IP

HTTP HyperText Transfer Protocol: It is the Internet protocol responsible for transferring and viewing web pages. It provides a way for web clients and web servers to communicate

with each other by sending and receiving messages.

DATA TRANSMISSION MEDIA:

Data transmission media refers to the medium used for transmitting data between the Connected devices in a network Transmission media can be broadly classified into guided and unguided media. Guided media: - (also called wired press) provides a physical path between the communicating devices in a network mainly used for small LAN. Different Voes of guided media include twisted pair cable, coaxial cable and fibre optic cable.

Unguided media: - An unguided press (also called wireless news) is a type of transmission

media that sends or receive the data through space does not involve any cable between two communicating devices.

VIVO V9 perfect for business use

2018-11-09T10:32:00.002-08:00

Is VIVO V9 perfect for business use?

When Vivo V9 was launched in India, it was the first Android smartphone to come up with the Nokia in this market. There were 4 GB RAM with Qualcomm Snapdragon 626 processor. After reviewing this phone, we came to the conclusion that it is quite powerful compared to the rest. But in a few days in the price range of 20,000 rupees, the more vigorous phones were dropped, after which Vivo V9 seemed a little expensive.
For example, Xiaomi Mi A2 (review) comes with more Powerful Snapdragon 660 processor and its price is 16,999 rupees. Shoomi's Poco F1 handset is a powerhouse device found at an initial price of Rs 20,999. In response to the growing challenges, the price of Vivo V9 (review) was cut. Now the company has dropped Vivo V9 Pro into the market. It comes with much better hardware and costs 17,990 rupees. Has VivoV9 Pro become a better package after hardware gets better? Let's know ...

Vivo V9 Pro Design
Vivo V9 Pro and VivoV9 are similar in appearance. It's slim. The grip is good because of the curved edges. Like the VivoV9, VivoV9 Pro is top-notch in the display of the display. In this same notch, earpiece, sensors, LED notifications and selfie cameras have got a place. Notch is very compact. Leaving the lower part, the screen is extremely thin on the other side. Vivo has been able to control the weight of this phone, it is 150 grams.

At the bottom, there are 3.5mm headphone jacks, micro-USB ports and loudspeaker grills. We did not like the headphone jack position. It is because of the inconvenience of playing games in landscape mode. There is a SIM tray slot on the left side of the device which has a dual nano-SIM and a separate microSD card slot. There are power and volume buttons on the left side. It is easy to reach them. Nothing at the top.

Vivo

Vivo V9 Pro has dual camera setup on the backside. This is also a single LED flash and fingerprint sensor. By the way, premium material is used to make most of the device in this price range. But Vivo has used plastic in V9 Pro. The VivoV9 Pro has been made available in Black and Nebula Purple colours. We've reviewed the Black variant. To provide the premium look, the camera module has been given the Golden Highlight in branding of RIM, fingerprint scanner and Vieu. The phone comes with the first screen protector. Apart from this, there is a transparent cover in the retail box. In the retail box, you will find earphones along with a 10-watt charger.

Vivo V9 Pro Specifications and Software
The main difference in the VivoV9 and VivoV9 Pro is the Snapdragon 660 processor. Vivo has decided to use more powerful chipsets this time and has 6 GB RAM with it. Inbuilt storage is 64 GB and if needed, up to 256 GB MicroSD card can be used. 6.3 inch IPS display is full-HD + resolution. Viewing angles are good. There is not much difficulty in reading out on the outside screen.

Apart from the Powerful Processor, there have been some other changes in the Pro Model. Vivo has set up a 13 megapixel + 2-megapixel camera with its VVV 9 smartphone, while the V9 model comes with 16 megapixels + 5-megapixel shooter. At the same time, the VVV 9 Pro for Selfie comes with a 16-megapixel sensor while the VVO 9 has a 24-megapixel camera. Bluetooth 5.0, Dual-Band Wi-Fi, GPS, GLONASS, USB-OTG and FM Radio are provided for connectivity. For both the SIM 4G VoLTE support is available.
Low light camera performance was worse than average. The noise was in the control, but the pictures came from Grenney. With Vivo V9 Pro you will be able to take beautiful selfies. The screen flash works out in low light. Portrait mode is also available for the selfie camera and its edge detection is good.

With both the camera setup of V9 Pro, you will be able to record up to 1080 pixels of video. This is shocking because VVO V9 has 4 video recording support. Due to no video stabilization, the footage shakes. We found that you can activate the beautification mode during video record or video call. Camera sensor replacement does not seem to have any major impact on the output.

Our decision
Vivo has kept the price of V9 Pro more aggressive than other products, including VivoV9. This phone has a powerful processor and more RAM does not have trouble with multitasking. But this time different camera sensors have been used to keep the price low. The good thing is that it has not had a big impact on-camera performance. The Vivo V9 Pro of Rs 17,990 is cheaper than the VivoV9, which still has a list of Rs 18,990. In such a situation, we can suggest you buy Pro Model without hesitation.

Vodafone and Airtel new plan

2018-11-09T10:14:00.001-08:00

Vodafone Idea will also run 2G-3G towers for 4G service, on the way of Airtel

Delhi (Tech Desk) Airtel has started shutting down 2G-3G towers to expand its 4G service. Now Vodafone Idea, the country's largest telecom service provider, is going to shut down 2G-3G towers for expanding its 4G service. Vodafone Idea and Bharti Airtel have decided to challenge the 4G service of Reliance Jio across the country. According to media reports, Vodafone Idea could use the spectrum of its 900MHz for 2G instead of better 4G service. Currently, the company uses the 2100MHz spectrum for 3G service. Vodafone Idea has started preparing for this. The company is currently testing this service in Mumbai, where the 900MHz band is being used for 4G service. Now the testing of this service is being done for Tamilnadu, UP West and West Bengal Circle. At present, the 900MHz spectrum of 900MHz is available in Vodafone Idea and the spectrum of 2100MHz is available in 22 circles. On the other hand, Bharti Airtel is also going to use the 900MHz spectrum for the 4G service in the next three to four months. Airtel is using 900MHz spectrum towers for 2G service, while the 2100MHz spectrum is being used for 3G service. In order to use the spectrum of 900MHz of these two telecom companies for 4G service, the users of these companies can get better connectivity of 4G in the country.

cc vs bcc. Main difference between them.

2018-09-28T08:06:00.000-07:00

let's read this article

Hello, friends, I am Shashwat from techy Shashwat I am going to show you two unique things about Gmail so read this post carefully. Gmail will all be used for you. cc vs bcc.

What is the Cc Aur Bcc? Cc Aur Bcc Mein What's the difference?

Whenever we send an email, We have 2 Advance Options coming out. Those named Cc and Bcc. What is Cc or Bcc? Is Cc or Bcc Me a Difference? What are Cc and Bcc? Difference Between Cc and Bcc? Today, we will learn about these differences. What are its advantages? Should we use it or not? Answers to all these questions in this article.
If you use Gmail to send e-mails you must have seen the option of Cc and Bcc. The option of Cc and Bcc is displayed to us when we click on To. Cc and Bcc are used for most companies or for business. Where more email is to be used it is used.

Main

But sometimes we also need it. If you do not know about it, then there must be informed about it. Because this is a lot of work and if you do a job in any company, then this information is very important for you. So whenever you ask someone about Cc and Bcc, you should not be ashamed.

Main

To send an email, we click on To so that we can send e-mail and enter the recipient's E-mail ID. But after clicking on to do two options in front of us and open cc and bcc. If you do not know about it then you should read this article in detail.

Do you have to

Whenever we send an e-mail to any person, in To, we enter the email ID of the person we want to send an email to. It is mostly used to send email to a single person. But it is not necessary that we can send an e-mail to one or two people only.
If you want, you can send 10 or 15 people together with an Email ID in ToE and send an email. But all the people you put in the ToE will know that this email is sent to anyone other than me.

What's the matter

The full form of the Cc is Carbon Copy. It is also almost like to be. But in this, we can send a copy of an email to multiple people. The difference is that the person who adds a copy of the email to the Cc also goes away.
But both the people with To and Cc know that to whom this email was sent to anyone and also the E-mail ID can be seen. You can also use it to send email to more people simultaneously.

What is bcc?

Bcc's full form is Blind Carbon Copy. Bcc is totally different from To and Cc. You can also call it Advanced Feature. People with to and cc can see each other's e-mail ID. If you use Bcc to send an email, then Bcc will be hidden from both (To and Cc).
If we send the same E-mail to 3 people, add one to the To and add another person to Cc, and add the third person to Bcc, To and Cc can see each other's email ID. To whom is this email sent to anyone other than this email? But the person with Bcc will neither see To-To nor will anyone be seen with Cc, i.e. that will remain secret from both.

How many people were sent an email to Bcc

How many people were sent an email to Bcc, except E-mail sender, meaning that no one except the sender would be able to know which mail was sent to Bcc? If you talk about Bcc, then the person with Bcc can see the person's email ID to To and Cc. But people with to and cc cannot see the ID of the Bcc. That is, they can not find the email ID that they have added to the Bcc.
If we want to send email to more people, and all those humans do not even see each other's ID, then you can use Bcc to send an email to this method. With this method, our email also goes to more people, and people do not even know that the email has been sent to anyone other than us. So the most important thing is that in Bcc it is the person's email ID that remains secret.
You can comment by telling friends how it's the Trick of Email. Would you like to use Bcc now? You must give your suggestion in the Comment section. Share it by clicking Share Button so that more people can know about it.
