3. Introduction
What is web
?
Web, which is also known as a World Wide
Web, is a collection of websites or web
pages stored in web servers and connected
to local computers through the internet.
The World Wide Web was invented by a
British scientist, Tim Berners-Lee in 1989
These websites contain text pages, digital
images, audios, videos, etc. Users can
access the content of these sites from any
part of the world over the internet using their
devices such as computers, laptops, cell
phones, etc.

5. The servers store and transfer web pages or information to user's
computers on the network when requested by the users. A web server is a
software program which serves the web pages requested by web users
using a browser. The computer of a user who requests documents from a
server is known as a client. Browser, which is installed on the user'
computer, allows users to view the retrieved documents.
