HOW THE INTERNET GOT STARTED
Some thirty years ago , the Rand corporation , America's formost cold war think
tank, faced a strange straegic problem. How could the US authrieties succesfully
communicate after a nuclear war?
Postnuclear America would need a comand-and-control network, linked from city
to city , state to state, base to base . But no matter how throughly that network was
armored or protected , its switches and wiring would always be vulnerable to the impact
of atomic bombs. A nuclear attack would reduce any conceivable network to tatters.
And how would the network itself be commanded and controlled ? Any central authority,
any network central citadel, would be an obvious and immediate target for man enemy
missle. Thecenter of the network would be the very first place to go.
RAND mulled over this grim puzzle in deep military secrecy, and arrived at a
daring solution made in 1964.The principles were simple . The network itself would be
assumed to be unreliable at all times . It would be designed from the get-go to tyranscend
its all times . It would be designed from the get-go to transcend its own unrreliability. All
the nodes from computers in the network would be equal in status to all other nodes , each
node with its own authority to originate , pass , and recieve messages. The messages
would be divided into packets, each packet seperatly addressed. Each packet would begin
at some specified source node , and end at some other specified destination node . Each
packet would wind its way through the network on an individual basis.In fall 1969, the
first such node was insalled in UCLA. By December 1969, there were 4 nodes on the
infant network, which was named arpanet, after its Pentagon sponsor.
The four computers could even be programed remotely from the other nodes. thanks to
ARPANET scientists and researchers could share one another's computer facilities by
long -distance . This was a very handy service , for computer-time was precious in the
early '70s. In 1971 ther were fifteen nodes in Arpanet; by 1972, thirty-seven nodes. And it
was good.
As early as 1977,TCP/IP was being used by other networks to link to
ARPANET.ARPANET itself remained fairly tightly controlled,at least until 1983,when its
military segment broke off and became MILNET. TCP/IP became more common,entire
other networks fell into the digital embrace of the Internet,and messily adhered. Since the
software called TCP/IP was public domain and he basic technology was decentralized and
rather anarchic by its very nature,it as difficult to stop people from barging in linking up
somewhere or other. Nobody wanted to stop them from joining this branching complex of
networks,whichcame tobe known as the "INTERNET".
Connecting to the Internet cost the taxpayer little or nothing, since each node was
independent,and had to handle its own financing and its own technical requirements. The
more,the merrier. Like the phone network,the computer network became steadily more
valuable as it embraced larger and larger territories of people and resources.
A fax machine is only valuable if everybody eles a fax machine. Until they do, a fax is
just a curiosity. ARPANET, too was a curiosity for a while. Then computer networking
became an utter necessity.
In 1984 the National Science Foundation got into theact,through its office of
Advanced Scientific Computing.
The new NSFNET set a blisteing pace for technical advancement linking
newer,faster,shinier supercomputers,through thicker, faster links,upgraded and
expanded,again and again,in l986,l988,l990.And other government agencies leapt
in:NASA,National Institutes of Health,Department of Energy,each of them maintaining a
digitl satrapy in the INTERNET confederation.
The nodes in this growing network-of-networks were divided up into basic
varieties. Foreighn computers,and a few American ones chose to be denoted by their
geographical locations. The others were grouped by the six basic Internet domains --gov,
{government} mil {military}edu{education} these were of course, the pioneers
Just think, in l997 the standards for computer networking is now global. In 1971, there
were only four nodes in the ARPANET network. Today there are tens of thousands of
nodes in the Internet,scattered over forty two countries and more coming on line every
single day. In estimate, as of December,l996 over 50 million people use this network.
Probably, the most important scientific instrument of the late twentieth century is the
INTERNET. It is spreading faster than celluar phones,faster than fax machines. The
INTERNET offers simple freedom. There are no censors,no bosses,etc. There are only
technical rules, not social, political,it is a bargain you can talk to anyone anywhere,and it
doesnt charge for long distance service. It belongs to everyone and no one.
The most widely used part of the"Net" is the world Wide Web. Internet mail is E
mail a lot faster than the US Postal service mail Internet regulars call the US mail the
"snailmail"File transfers allow Internet users to access remote machines and retrieve
programs or text. Many internet computers allow any person to acess them anonymously
to simply copy their public files,free of charge. Entire books can be transferred through
direct access in a matter of minutes.
Finding a link to the Internet will become easier and cheaper. At the turn of the
century,Network literacy will be forcing itself into every individuals life.
