The World Wide Web (abbreviated as WWW or W3, 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.
Using concepts from his earlier hypertext systems
like ENQUIRE, British engineer and computer scientist Sir Tim
Berners-Lee, now Director of the World Wide Web
Consortium(W3C), wrote a proposal in March 1989 for what would
eventually become the World Wide Web. At CERN, a European
research organization near Geneva situated on Swiss and French
soil, Berners-Lee and Belgian computer scientist Robert
Cailliau proposed in 1990 to use hypertext "to link and access
information of various kinds as a web of nodes in which the user can
browse at will", and they publicly introduced the project in December
of the same year.
3. In the may 1970 issue of popular
science magazine, arthur c. Clarke
predicted that sattelites would
someday “bring the accumulated
knowledge of the world to your
fingertips “ using a console that
would combine the functionally of the
xerox,telephone,televesion an a
small computer,allowing data
transfer and wide conferencing
around the globe.

march 1989 ,Tim berners-lee
wrote a proposal the referenced
enquire database and software
project he had built in 1980, and
described a more elaborate
information managemant system .
5. netiquette (short for “network etiquette” or
“”internet etiquette) is a set of social conventions
that facilitate interaction over networks,
ranging from usenet and mailing lists to blogs and
forums. These rules were described in IETF rfc 1855.
however, like many internet phenomena, the
concept and its application remain in a state of
flux, and vary from community to community. The
points most strongly emphasized about USENET
netiquette often include using simple electronic
signatures
And avoiding multiposting,crossposting,off-topic
posting,hijacking a discussion thread, and other
techniques used to minimize the effort required to
read a post or a thread.

Common rules for e-mail and USENET such as
avoiding flamewars and spam are constant across
most mediums and communities. Another rule is to
avoid typing in ALL CAPS or grossly enlarging
script for emphasis, which is considered to be the
equivalent of shouting or yelling. Other commonly
shared points, such as remembering that one's posts
are (or can easily be made) public, are generally
intuitively understood by publishers of Web pages
and posters to USENET, although this rule is
somewhat flexible depending on the environment. On
more private protocols, however, such as e-mail
and SMS, some users take the privacy of their posts
for granted. One-on-one communications, such as
private messages on chat forums and direct SMSs,
may be considered more private than other such
protocols, but infamous breaches surround even
these relatively private media. For example, Paris
Hilton's SidekickPDA was cracked in 2005, resulting
in the publication of her private photos, SMS
history, address book, etc.

A web search engine is designed to search for
information on the World Wide Web. The
search results are generally presented in a
line of results often referred to as search
engine results pages (SERPs). The information
may be a specialist in web pages, images,
information and other types of files. Some
search engines also mine data available
in databases or open directories. Unlike web
directories, which are maintained only by
human editors, search engines also
maintain real-time information by running
an algorithm on a web crawler.

During the early development of the web, there was a
list of webservers edited by Tim Berners-Lee and hosted
on the CERN webserver. One historical snapshot from
1992 remains.As more webservers went online the
central list could not keep up. On theNCSA site new
servers were announced under the title "What's New!"
The very first tool used for searching on the Internet
was Archie. The name stands for "archive" without the "v".
It was created in 1990 by Alan Emtage, Bill Heelan and J.
Peter Deutsch, computer science students
at McGilUniversityin Montreal. The program downloaded
the directory listings of all the files located on public
anonymous FTP (File Transfer Protocol) sites, creating a
searchable database of file names; however, Archie did
not index the contents of these sites since the amount of
data was so limited it could be readily searched
manually.
9.
The rise of Gopher (created in 1991 by Mark
McCahill at the University of Minnesota) led
to two new search
programs, Veronica and Jug head. Like Archie,
they searched the file names and titles
stored in Gopher index systems. Veronica
(Very EasyRodent-Oriented Net-wide Index
to Computerized Archives) provided a
keyword search of most Gopher menu titles in
the entire Gopher listings. Jug head
(Jonzy'sUniversal Gopher Hierarchy Excavati
on And Display) was a tool for obtaining menu
information from specific Gopher servers.
While the name of the search engine "Archie"
was not a reference to the Archie comic book
series, "Veronica" and
