INTRODUCTION
Computer technology has a deep impact on education. It helps an effective storage and
retention of information. Internet has been perhaps the most outstanding innovation in the field
of communication in the history of mankind. Information is probably the biggest advantage
internet is offering.
It is notable that the growth of internet and technologies is rapidly increasing day-by day.
It’s mainly useful for information search and retrieval on the web. The concept of a web resource
is primitive in the web architecture and is used in the definition of its fundamental element. Web
based information designed to help users standard websites (information available) are being
developed by many private and public research centers. It encompassing everything or entity that
can be identified, named, addressed or handled in anyway what over in the web at large, or in
any networked information system. So it helps what we need is a practical uses friendly and ad-free
format information is probably the biggest advantage web resources is offering. It is a virtual
treasure trove of information. Any kind of information on any topic under the sun is available on
this. The search engines like Google, yahoo is at our service on the internet. There is a huge
amount of information available for just about every subject known to man, ranging from
government law & services, conference, marketing, new ideas and technical support, the list is
endless.
Student and teachers are among top uses who surf for reaching topics of their interest.
Numerous resource units are available which offers different level of information gathering
technique. It allows students to learn at their own pace.

WWW
The World Wide Web is an important application that uses internet data transport
mechanism. The web is a system with universally accepted standard of storing, retrieving,
formatting and displaying information. It handles all type of digital information including text,
hypermedia, graphics and sound. The technology underlying www created by Timothy Berners –
Lee, who in 1989 proposed a global network of hypertext document that would allow researchers
to work together.
The web is based on a standard type text language called Hypertext Markup Language
(HTML) which formats documents and incorporates dynamics hypertext links to other
documents stored on the same or different computers. Offering information through the web
requires establishing a homepages, which is a text and graphical screen display that usually
welcomes the users and explains the organization that has established the page. In most cases the
home page will lead the users to other pages. All the pages of a particular organization or
individual known as website. Different websites is available to gather information regarding
various topics.
To access a website, the user must specify a uniform resource locator (URL), which
points to the address of a specific resource on the web. For instance the URL for Microsoft is
http://www.microsoft.com. HTTP stands for hypertext transfer protocol, which is the

6. 3
Communication standard used to transfer pages across the www pages of the internet. HTTP
defines how messages are formatted and transmitted and what actions web servers and browsers
should take in response to various commands.
Users primarily access the web through software application called browsers. The
commonly used internet browsers are Netscape communicator, Microsoft internet explorer,
Mozilla Firefox, opera etc.
Eg: For searching about wildlife it should be written as http:/www.wildlife.com. Hence
we can easily access information using this.
SEARCH ENGINES
A web search engine is designed to search for information on the www. The search
results are usually presented in a list of results and are commonly called hits. The information
may consist of web pages, images, information and other types of files. Basically a search engine
is a software program that searches for sites based on the words that user designate as search
terms. Search engines looks through their own databases information in order to find what it is
that the user is looking for. Different search engine searches for sites based on the word that uses
designate as search term.

Search engines are not simple. They include incredibly detailed processes and
methodologies, and are updated all the time. All search engines go by this basic process when
conducting search processes, but because there are differences in search engines, there are bound
to be different results depending on the engine we use. Major search engines such as Google,
Yahoo, AltaVista provides results that can run for pages. Individual websites may use a search
engine to index and retrieve the content of just their own site. An alternative to use search engine
is to explore a structured directory of topics. Yahoo is the most widely used directory on the
web. A number of web portal sites offer both the search engine and directory approaches to
finding information.
WIKIS
A wiki is a websites that allow the easy creation and editing any number of interlinked
webpage. Wiki may exist to serve a specific purpose and in such cases, users use their editorial
right to remove material that is considered ‘off topic’. Such in case of the collaborative
encyclopedia Wikipedia. So it is the simplest online data base that could possibly work. Wikis
are typically powered by wiki software and are often used to create websites.

CONCLUSION
Web resource is a tool which helps to access information. There are many reasons
building a website requires that use obtain the right tools and resources. By using standard
resources our visitor are able to use web page. The right resources also make it easy for sites for
surfers to use sites. Search engine would index websites if the pages conform to their rules. Web
tools make the web design job easy.
Now that we are equipped with the right knowledge we can go about our web design with
the assurance that we are going to produce something appealing and acceptable to most browses.
Hence they provide the most vivid information about any problem which less down the
complication. So the use of web resource for accessing information is rapidly increasing. The
Web is not only a space of information, it is a tool to connect people with shared interests. The
power of the Web is to enable anybody to share information. People had and fulfilled most of
these needs of information before the Web, and there are many other ways of sending and
receiving information. For decades, the major sources of information were newspaper, radio and
TV. The internet has dramatically impacted the education system in the last few years and this
trend will certainly continue well into the future. Many have discovered the advantages of having
a presence on the internet and have successfully addressed corporate objectives by integrating
their web site as part of their educational systems.
