Computer

Network

Computer networks

have become

integral part of our

everyday lives. It’s

difficult to perform

our simple daily

routine tasks in the

absence of

computer network.

We use them to take cash from the bank local ATM. Whenever we send mail or

browse the web, we rely on the world’s largest computer network, the Internet.

2 Computer Networks : Grade 10

In simple term computer network is the interconnection between two or more

computing devices for the purpose of resource sharing.

A group of computers and peripheral devices connected together by communication

channel to enable users to share and exchange information.

Application of computer networks

A network is a collection or set of computing devices connected to one another to

establish communication and also share available resources. A network will

comprise of software and hardware devices. They help us to transfer data from one

point to another within the network. Computer networks plays an important roles in

the all of the area of human life. They have great impact on the activities and the

work do. The development of computer networks have changed the way of work we

do. Some of the applications of the computer network are mentioned below:

Business Applications

Most of the business organizations have large numbers of computers to do different

types of works. In earlier days these computers were stand alone, isolated from

others, but at some point, management may have decided to connect these computers

to correlate information about entire company.

A business organization can easily share its resources with the help of computer

network and make all programs, equipment and data available to anyone on the

network without regard to the physical location of the resource and the user. A group

of office workers can share the single printer. Along with the hardware resources

such as printer, CD, scanner most of the business organizations can share data and

information. Such information may include customer records, inventories, financial

statements and others. So all small to large business organization needs computer

network computer network for the remote access of data and information by

stakeholders. Almost every business uses computers to complete daily tasks. From

making contact with clients to input data for reports, computers allow businesses a

more efficient way to manage affairs when compared to traditional paper and heap

of files.

Computer Networks : Grade 10 3

Apart from sharing the hardware and information the computer network provides

strong communication medium among employee and customers. Most of the

business personnel use the email for their communication. Computers give

businesses access to email, instant messaging and custom customer contact systems.

Computerized phone systems allow for automated support during off hours and a

virtual operator can quickly direct callers to the correct department for faster support.

For promoting their business several business organization are keen in using the

computer network. They advertise their products as well as their company using

several ads in the internet.

The uses of computer network can be listed as

 Communication

 Marketing

 Budgeting and forecasting

 Storage

 Documents and Reports

 Education

 Research

 Data mining

 Customer relation

Home Application

In earlier days the use of computer at home was just for playing games, watching

videos or word processing works. But due to the development of internet technology

the use of computer at home has been rapidly changed. The probable main reason

for having computer at home is for Internet access. Nowadays there are several

computing devices in home along with the computer such as smartphones, smart TV,

printers etc. people needs to connect these devices with each other for

communicating and sharing information. Computer network provides helps them to

communicate with each other. A home user can use computer network for

 Accessing the remote information: People can have access to the information

on any subject either news, business, politics and many others by surfing the

internet. Educational and informative websites are available to download

books, tutorials etc. to improve their knowledge and learn new things.

 Person to person communication: People can communicate with friends and

family on the internet using different software like Skype etc. One can

interact with friends over social media websites like Facebook, Twitter. They

can also share photos and videos with friends. Video calls, group chat, group

call are based on computer network which are the most modern ways of

communicating among people.

 Interactive entertainment: People can find entertainment on the internet using

computer. They can watch movies, hear songs and download different stuff.

They can also watch live matches on internet.

 Electronic commerce: E-commerce or Electronic Commerce is the process of

buying or selling goods online. Due to the busy life people don’t get time to

go for shopping, moreover that different online shopping sites provide

varieties of goods and deliver to our doorsteps. It has make shopping easier.

By sitting in the room, using their computer network people can buy their

needed goods.

Mobile Application

Mobile application is one of the growing concern of the computer network. People

are mostly using the mobile devices such as tablet, smart phones, PDAs (Personal

Digital Assistants), notebooks for computing. Many of these people have desktop or

laptop computer in their home still using these mobile devices because these devices

are easier to use and can be carried with ease with the feature of wireless connection.

(Tanenbaum, 2003)

Basic Terms used in Computer Network:

Client: Those less powerful computers on which the user runs the applications are

client. They have less processing speed and storage capacity in comparison to server

computers and they further request to the server computers for information.

Server: The more powerful computers than client computers and responsible for

providing services to those client computers are called server.
