collection of hyperlinked documents which from part of the internet. It is
a subset of the internet and it present text, images, animation, video,
sound and other multimedia in a single interface.
Invention:
In the 1990s the explosion of Internet application due to the
emergence of the World Wide Web (WWW). The web was invented at
CERN by Tim Berners – Lee. This invention has added the commercial
application to the Internet.
3. Architecture:
The WWW today is a distributed client-server service,
in which a client using a browser can access a service using
server. However, the service provided is distributed over
many location called sites. Each site holds one or more web
pages. Each web page can contain some links to other web
pages in the same or other sites. Each web page is a file with
a name and address.
4. WWW contains some parts they are:
1. URL (Uniform Resource Locator)
2. DNS (Domain Name System)
3. Web browser
4. Search engine
And some protocols like, HTTP, TCP etc.
URL: A web page, as a file, needs to have a unique identifier to distinguish it
from other web pages. To define a web page, we need three identifiers: host,
port and path.
5. DNS: Domain name system is a hierarchical naming system for computers in
the internet. Most importantly it converts or translate human meaningful domain
names in to the numerical (binary) identifiers associated with networking
equipment for the purpose of locating and addressing these devices world wide.
6. Web Browser: A browser is a computer program that
accesses web pages and displays them on the computer screen. It is the basic
software that is needed to find, retrieve, view and send information over
internet. In fact, to access the World Wide Web, the user requires a web
browser. Example of web browser is Microsoft Internet Explorer.
7. Search Engine: The internet provide access to a wealth of information
on countless topics contributed by people throughout the world. However, the
internet is not a library in which all its available items are identified and can
require by single catalog. In fact, no one knows how many individual files (could
be millions) resides on the internet. Hence, to conduct a search on the internet a
special search tool known as search engine are used.
