what is Internet, WWW, Server, web Server/Browser?
Internet:
The Internet is a global system of interconnected
computer networks that use the standard Internet Protocol Suite (TCP/IP) to
serve billions of users worldwide. It is a network
of networks that consists of millions of private, public academic,
business, and government networks.
WWW:
The World Wide Web, abbreviated as WWW and commonly known as
the Web, is a system of interlinked hypertext documents accessed via the
Internet. With a web browser, one can view web pages that may contain text,
images, videos, and other multimedia and navigate between them via
hyperlinks.
Emergence of Web:
Between
the summers of 1991 and 1994, the load on the first Web server
("info.cern.ch") rose steadily by a factor of 10 every year.
In 1992 academia, and in 1993
industry, was taking notice. World Wide Web Consortium is formed in September
1994, with a base at MIT is the USA, INRIA in France, and now also at Keio
University in Japan.
With the dramatic flood of rich
material of all kinds onto the Web in the 1990s, the first part of the dream is
largely realized, although still very few people in practice have access to
intuitive hypertext creation tools.
The second part has yet to happen, but there are signs and plans which make us confident. The great need for information about information, to help us categorize, sort, pay for own information is driving the design of languages for the web designed for processing by machines, rather than people. The web of human readable document is being merged with a web of machine-understandable data. The potential of the mixture of humans and machines working together and communicating through the web could be immense.
WEB Servers:
To view and browse pages on the Web, all you need is a web browser. To publish pages on the Web, you need a web server. A web server is the program that runs on a computer and is responsible for replying to web browser requests for files. You need a web server to publish documents on the Web. When you use a browser to request a page on a website, that browser makes a web connection to a server using the HTTP protocol. The browser then formats the information it got from the server. Server accepts the connection, sends the contents of the requested files and then closes.
WEB Browsers:
A web browser is the program you use to view pages and navigate the World Wide Web. A wide array of web browsers is available for just about every platform you can imagine. Microsoft Internet Explorer, for example, is included with Windows and Safari is included with Mac OS X. Mozilla Firefox, Netscape Navigator, and Opera are all available for free.
What the Browser Does The core purpose of a web browser is to
connect to web servers, request documents, and then properly format and display
those documents. Web browsers can also display files on your local computer,
download files that are not meant to be displayed. Each web page is a file
written in a language called the Hypertext Markup Language (HTML) that includes the text of the
page, a description of its structure, and links to other documents, images, or
other media.
Protocols:
In computing, a protocol is a set of rules which is used
by computers to communicate with each other across a network. A protocol is a
convention or standard that controls or enables the connection, communication,
and data transfer between computing endpoints.
Internet Protocol Suite:
The Internet Protocol Suite is the set of
communications protocols used for the Internet and other similar networks. It
is commonly also known as TCP/IP named from two of the most important protocols
in it: The Transmission Control Protocol (TCP) and the Internet Protocol (IP),
which were the first two networking protocols defined in this standard.
