FEATURES.

2. INTRODUCTION
• The Internet, Information Super Highway provides
access to communication services and information
resources to millions of users around the global. The
Internet services include direct communication (Email,
Chat), Online conference (Usenet, Chat, Email
discussion), World information resources (World Wise
Web) Gopher, Archie, Newsgroup, Bulletin Board, and
File Transfer Protocol (FTP) and many other tools and
resources. A brief detail of both the features and tools

3. WORLD WIDE WEB (WWW)
• The Web (World Wide Web) consists of information organized
into Web pages containing text and graphic images.
• It contains hypertext links, or highlighted keywords and images
that lead to related information.
• A collection of linked Web pages that has a common theme or
focus is called a Web site.
• The main page that all of the pages on a particular Web site are
organized around and link back to is called the site’s home
page.

4. HYPERTEXT
• Hypertext is a method of preparing and publishing
text in which users can choose their own paths
through material. The text is broken into small units
such as single pages called Nodes. Hyperlink are
embedded into the text. Typically user has a graphical
user interface (GUI) on which he clicks a button to
navigate through different pages.

5. HYPERLINK
•In computing, a hyperlink is a reference to
data that the reader can directly follow
either by clicking or by hovering. A
hyperlink points to a whole document or
to a specific element within a document.
Hypertext is text with hyperlinks.

6. 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.
• Although browsers are primarily intended to use the World Wide Web,
they can also be used to access information provided by web servers
in private networks or files in file systems.
• The major web browsers are Firefox, Internet Explorer/Microsoft

7. WEB PAGE
• A web page (or webpage) is a web document that is
suitable for the World Wide Web and the web browser.
A web browser displays a web page on a monitor or
mobile device. The web page is what displays, but the
term also refers to a computer file, usually written in
HTML or comparable markup language. Web browsers
coordinate the various web resource elements for the
written web page, such as style sheets, scripts, and
images, to present the web page.

8. WEBSITE
• 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.Web pages, which
are the building blocks of websites, are documents, typically

9. HTML ( HYPERTEXT MARKUP
LANGUAGE )
• The public files on the web servers are ordinary text files,
much like the files used by word-processing software.
• To allow Web browser software to read them, the text
must be formatted according to a generally accepted
standard.
• The standard used on the web is Hypertext markup
language (HTML).
• HTML uses codes, or tags, to tell the Web browser
software how to display the text contained in the

10. HTTP ( HYPERTEXT TRANSFER PROTOCOL)
• The transfer protocol is the set of rules that the computers use
to move files from one computer to another on the Internet.
• The most common transfer protocol used on the Internet is the
Hypertext Transfer Protocol (HTTP).
• Two other protocols that you can use on the Internet are the
File Transfer Protocol (FTP) and the Telnet Protocol

11. WEB SERVER
• A web server is an information technology that processes requests via HTTP,
the basic network protocol used to distribute information on the World Wide
Web. The term can refer either to the entire computer system, an appliance,
or sCommon features[edit]
• Virtual hosting to serve many web sites using one IP address
• Large file support to be able to serve files whose size is greater than 2 GB
on 32 bit OS
• Bandwidth throttling to limit the speed of responses in order to not saturate
the network and to be able to serve more clients
• Server-side scripting to generate dynamic web pages, still keeping web
server and website implementations separate from each interspecifically to
the software that accepts and supervises the HTTP requests.
