History

President Eisenhower in the 50’s and 60’s
instructed U.S. Academic research centres including

military, to develop a network that could survive

enemy attack.

Paul Baran (1960) envisioned that communication
network in the birth of Arpanet. The answer was to
decentralize everything, including routing, and have
no essential H.Q. and also to have redundant paths.
However, the military ignored this in total centralization
leaving itself with an enormous vulnerable H.Q. at the

Pentagon.

The Internet is a World Wide Atlas consisting of
Countries and Roads. To prevent traffic congestion
protocol and rules were developed. The structure of

the Internet consists of a World Wide computer

             network that has revolutionised the global communications.
   Millions of computers are connected together through
          the telephone system, allowing us to exchange information
          with any another person on the network, for athe price of a
        telephone call. You can connect to the Internet by means

of a WAPphone, television and games consoles.

Structure
The Internet is made up of the following:

The World Wide Web (WWW)

Electronic Mail (email)

Newsgroups

File transfer protocol (FTP)

Bulletin boards (BBS)

Remote computer access (Telnet).

The components familiar to most people are the World Wide Web and email.

Funding and Ownership

<>o one actually owns the Internet, and no single person or organization controls the Internet in its entirety. There are many organizations, corporations, governments, schools, private citizens and service providers that all own pieces of the infrastructure.

Internet Engineering Task Force (IEFT)

Internet Engineering Steering Group (IESG)

Internet Architecture Board (IAB)

Internet Assigned Number Authority (IANA)

Internet Research Task Force (IRF)

Internet Steering Group (IRSG)

The World Wide Web

The W.W.W. could be described as a library of pages consisting of graphics, sound, text, video and user input linked together via the Internet. On the W.W.W. documents etc are transferred from the server or computer that stores the information to your computer that is requesting the information using a specific protocol. Search engines often work by sending out “spiders” which are autonomous Internet programs that trawl the Web looking for and sending back information about sites they visit.
