HOw THE INTERNET FUNCTIONS?

A corporate network may have its computers connected through a local

area network. governed by certain rules. Further. this network may be

connected with other networks. But, if different networks are governed

by different rules, will they be able to communicate with one another?

Imagine a group of people having one Tamilian. one Bengali, one

Himachali. one Mizo and one from Maharashtra trying to communicate

with each other in their own native languages, failing to understand

what the other person is trying to say. Theretore. to communicate with

each other, some common standard must be followed.

Functioning of the Internet is not controlled by any one particular

organisation. It is managed by a group of voluntary organisations. These

voluntary organisations have formed the Intermet Society. They decide

e

on the rules, known as protocols, for communication over the Internet.

The different networks may have their own rules that they follow

internally. but when they communicate with each other. they must

follow some common rules. It's ike we speaking our mother tongue at

home, but while communicating in a mixed group. we use a common

language. mainly. Hindi or English.

7.3 HOW TO WORK WITH THE INTERNET?

In order to work with the Internet we need to know certain related terms

like www. web browsers, web pages, websites, etc. We should know how

to get connected to thhe Internet. Once connected how to use it.

Most of the terms on the Internet are prefixed with the term web.

The electronie pages seen on the Internet are known as web pages. A

web page can be defined as the document that we see on the Intermet.

Many web pages linked with each other combine to form a website. A

web page can be written in the language known as HTML (Hyper

Text Markup Language). HTML is a very simple language having a

number of options to represent text. Many other scripting languages

have now been developed which can be embedded into HTML. giving

it the power to interact with the users. (These are discussed in detail

in the next Unit). These dynamic web pages can take inputs from

users and give information accordingly taking in the location of the

user before displaying the weather forecast. For example, a protocol

called Hyper Text Transfer Protocol (HTTP) is used to transmit and

receive the web pages.

 WEB BrowsERS

The web is a collection of a huge amount of information. Every single

web page consists of some information and also a number of links.

which connects us to other related web pages. To visit the linked

web pages. Just click over the linked text and the next web page

opens up.
