2. Definition Of Internet
• The Internet is the global system of interconnected computer
networks that use the Internet protocol suite (TCP/IP) to link
billions of devices worldwide. It is a network of networks that
consists of millions of private, public, academic, business, and
government networks of local to global scope, linked by a
broad array of electronic, wireless, and optical networking
technologies.

3. Benefits of Internet
• The Internet provides opportunities galore,
and can be used for a variety of things. Some
of the things that you can do via the Internet
are:
• E-mail: E-mail is an online correspondence
system. With e-mail you can send and receive
instant electronic messages, which works like
writing letters.

4. • Access Information: The Internet is a virtual treasure trove of
information. Any kind of information on any topic under the
sun is available on the Internet.
• Shopping: Along with getting information on the Internet, you
can also shop online.
• Online Chat: There are many ‘chat rooms’ on the web that
can be accessed to meet new people, make new friends, as
well as to stay in touch with old friends.

5. Disadvantages of Internet
• Spending too much time at the desk with a computer can
harm your physical and mental health. Such people can
become reclusive and lonely. This could lead to low self-
esteem and a whole host of psychosomatic conditions.
• An over-reliance on the Internet can also lead to a general
lowering of mental capacity. Mental fatigue and a feeling
of lethargy can gradually creep in as a result of a
sedentary life sitting all day long in front of the computer
and surfing the Web. Lack of exercise can cause a general
deterioration in health and lead to a poor immune
response.

6. Full Form of WWW?
The Full form of WWW is
World Wide Web

7. • The World Wide Web (WWW) is an information space where documents and
other web resources are identified by URLs, interlinked by hypertext links, and can
be accessed via the Internet. The World Wide Web was invented by English
scientist Tim Berners-Lee in 1989. He wrote the first web browser in 1990 while
employed at CERN in Switzerland. The World Wide Web was central to the
development of the Information Age and is the primary tool billions of
people use to interact on the Internet.
• Web pages are primarily text documents formatted and annotated
with Hypertext Markup Language (HTML).

8. Definition of Web Browser
• A web browser (commonly referred to as
a browser) is a software application for
retrieving, presenting, and traversing
information resources on the World Wide
Web. An information resource is identified by
a Uniform Resource Identifier(URI/URL) and
may be a web page, image, video or other
piece of content. Hyperlinks present in
resources enable users easily to navigate
their browsers to related resources.

9. Disadvantages of web browser
• Danger of overload and excess information
• – It requires an efficient information search strategy
• – The search can be slow
• – It is difficult to filter and prioritize information
• – No guarantee of finding what one is looking for
• – There is a lot of apparently unconnected information
• – Net becomes overloaded because of large number of users
• – No regulation
• – No quality control over available data
• – The ease with which information can be constantly up-dated
• can cause problems of referencing

10. Definition Of web portal
• A web portal is most often one specially designed web
site that brings information together from diverse sources
in a uniform way. Usually, each information source gets its
dedicated area on the page for displaying information
(a portal); often, the user can configure which ones to
display. Variants of portals include smashups
and intranet "dashboards" for executives and managers.
The extent to which content is displayed in a "uniform way"
may depend on the intended user and the intended
purpose, as well as the diversity of the content. Very often
design emphasis is on a certain "metaphor" for configuring
and customizing the presentation of the content and the
chosen implementation framework and/or code libraries.

11. Uses of Web Portal
• A portal is a user facing aggregation point where multiple,
potentially unrelated functionalities and services are housed.
Usually, portals are used as a gateway to consumer type of
offerings such as searching, news, weather information,
electronic mail, and stock prices. Portals provide a single
location that users can turn to when they are looking for
information and services. Instead of spending a lot of time
searching through multiple locations, portals aggregate the
relevant information at a single, easy-to-remember location.

12. Definition of Search Engine
• Typically, Web search engines work by sending out
a spider to fetch as many documents as possible. Another
program, called an indexer, then reads these documents
and creates an index based on the words contained in
each document. Each search engine uses
a proprietary algorithm to create its indices such that,
ideally, only meaningful results are returned for
each query.
• As many website owners rely on search engines to send
traffic to their website, and entire industry has grown
around the idea of optimizing Web content to improve
your placement in search engine results. Learn more

14. Definition of Web site
• A website, also written as web site, is a collection of
related web pages, including multimedia content,
typically identified with a common domain name,
and published on at least one web server. A web
site may be accessible via a public Internet
Protocol (IP) network, such as the Internet, or a
private local area network (LAN), by referencing
a uniform resource locator (URL) that identifies the
site. All publicly accessible websites collectively
constitute the World Wide Web, while private
websites are typically a part of an intranet.

15. Benefits of Web Site
• Increase New Business
• Save Money
• Provide Information
• Beat the Competition
• Attract a New Type of Customer
• Develop a Brand

18. • A website is a collection of interlinked web pages
typically hosted from a single domain. A website is
accessible over the internet or a private network such
as Local Area Network (LAN) through an address
known as Uniform Resource Locator (URL).
• The URLs organize the web pages into a hierarchical
form which help a user to navigate through the pages.
A home page is included that usually is the starting
point of all navigation artifacts, including links to other
pages, an “About Us” page, or a “Contact Us” page.

20. • A web portal is a customized website that immerses
information from a wide array of sources in a
consistent and uniformed manner.
• For example, web portals are served in the form of
dashboards for company executives and managers.
How the content on a portal should be organized and
presented depends largely on the requirements of the
end users?
• A web portal may be customized based on the
restrictions of domain searches. An enterprise portal
usually has a consistent design and has the capability
to interact with applications and databases.
