8. Tim Berners-Lee invented the World
Wide Web in 1989.
the WWW project was initiated at
CERN (European Center for Nuclear
Research) to create a system to handle
distributed resources for scientific
research.
9. WWW :World WideWeb or web
WWW is a framework for accessing linked
documents spread out over millions of machines
all over the Internet. The WWW has a unique
combination of flexibility, portability, and user-
friendly features.
11. The Internet is the global system of
interconnected computer networks that uses
the standard Internet protocol (TCP/IP) to
communicate between networks and devices.
12. Developed in 60s and 70s by US Department of Defense
called ARPANET
90s: network : known as Internet.
Internet and Web is not the same thing: Web uses internet to
pass over the information.
14. A standard way of specifying the location of a web page, on the
Internet
It defines four things: method, host computer, port and path.
Method – protocol used to retrieve the document like HTTP.
Host– a computer where the information is located.
Port– optional port # of the server (default is 80)
Path– the path name of the file where the information is located
Method: // Host computer : Port / Path
eg: https://www.gla.ac.in/academics/department-of-computer-
engineering-application
15. HyperText Transfer Protocol is The protocol used to transfer
Web pages through the Internet.
HTTP is a “stateless” protocol which means that the
connection between the browser and the server is lost once the
transaction ends.
A protocol is a standard set of rules that allow electronic
devices to communicate with each other.
17. The WWW consists of a vast,
worldwide collection of documents.
These documents are known as Web
Pages, often just called pages for
short. The web pages are created by
using different markup languages.
18. Static web page are fixed content documents that are created
and stored in a server. The contents in the server can be
changed, but the user cannot change it.

point of time a fresh document is created for each request, the
contents of a dynamic document can vary from one request to
another.
19. A website is a collection of web pages and related content that
is identified by a common domain name and published on at
least one web server. Notable examples are

amazon.com.
20. a website is a location on the internet that is unique and which
is accessed via a web browser using a specific URL (web
address). Portals are also accessed via a web browser and
specific URL, but content is login protected and user-specific.
Example:
gla.ac.in is a website while
glauniversity.in:8085 is web portal
21. Web development refers to building website and deploying it
on the web. Web development requires use of scripting
languages both at the server end as well as at client end.
Client Side coding:
Ajax,Javascript,
Vbscript,
HTML, CSS ,..
Server Side coding:
ASP, CGI
Javascript,PHP
Python
Java, .NET ,..
