The solution was to establish a decentralized communications network without a central authority. All the nodes in the network would be equal in status to all other nodes and each node has the authority to originate, pass, and receive messages. The messages are divided into packets and each packet is separately addressed. Each message begins at a specified source node, winds its way through the network on an individual basis, and ends at some other specified destination node. A communication standard known as TCP/IP converts messages into streams of packets at the source and reassembles them back into messages at their destination. The brand-names, content, and ownership of the computers are irrelevant as long as they can speak TCP/IP. It is easy to link these computers to the network using the TCP/IP protocol. The network became known as the Intenet and the basic technology of this network is decentralized and anarchic. The Internet is a rare example of a true, modem, functional anarchy. There are no official censors, no bosses, no board of directors, no stockholders. In principle, any node can speak as a peer to any other node, as long as it obeys the rules of the TCP/IP protocols, which are strictly technical, not social or political. This "anarchy" may seem strange or even unnatural, but it makes a certain deep and basic sense. It's like the "anarchy" of the English language. Nobody owns English. As an English-speaking person, it's up to you to learn how to speak English properly and make whatever use you please. Everybody pitches in, and somehow the English language evolves on its own, and turns out workable. Though a lot of people earn their living from using, exploiting, and teaching English, "English" as an institution is public property and a public good. Much the same goes for the Internet. Would English be improved if the "The English Language, Inc." had a board of directors and a chief executive officer, or a President and a Congress? There would probably be a lot fewer new words in English, and a lot fewer new ideas. Connecting to the Internet cost the taxpayer little or nothing, because each node is independent and has to handle its own financing. Since TCP/IP is public-domain, many linked up to the network. 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. It is a bargain to the user. The Internet as a whole, unlike the phone system, does not charge for long-distance service or access time. Each group of people accessing the Internet is responsible for their own machine and their own section of line. The Internet is popular among scientists, and is probably the most important scientific instrument of the late twentieth century. The pace of growth is spectacular. It is spreading faster than cellular phones, and fax machines. The number of "host" machines with direct connection to TCP/IP have been doubling every year since 1988. The future of the Internet bids to be bigger and it is being upgraded and will be fifty times faster than the fastest network available today. The entire Encyclopedia Britannica will be transferred in one second, it will feature 3-D animated graphics, radio and cellular phone-links to portable computers, as well as fax, voice, and high definition television. A multimedia global circus What does one do with the Internet? Four things, basically: mail, discussion groups, file transfers, and long-distance computing . 1. Internet mail is "e-mail," electronic mail, faster by several orders of magnitude than the US Mail, which is scornfully known by Internet regulars as "snail mail." Internet mail is somewhat like fax. It's electronic text that you do not have to pay for. E- mail can also send software and certain forms of compressed digital imagery. New forms of mail are in the works. 2. The discussion groups, or "news groups," are a world of their own. This world of news, debate and argument is generally known as USENET. USENET is rather like an enormous billowing crowd of gossipy, news-hungy people, wandering in and through the Internet on their way to various private backyard barbecues. There are some 2,500 separate news groups on USENET. The variety of subjects discussed is enormous, and it's growing larger all the time. 3. File transfers allow Intenet users to access remote machines and retrieve programs or text. Many Internet computers allow any person to access them anonymously, and to simply copy their public files, free of charge. This is no small deal, since entire books can be transferred through direct Internet access in a matter of minutes. There are over a million such public files available to anyone who asks for them. Internet file-transfers are becoming a new form of publishing, in which the reader simply electronically copies the work on demand, in any quantity he or she wants, for free. Internet programs, such as "archie, gopher, world wide web, and WAIS." have been developed to catalog and explore these enormous archives of material. 4. Long-distance computing is still a very useful service. Programmers can maintain accounts on distant, powerful computers, run programs there or write their own. Scientists can make use of powerful super computers a continent away. Libraries offer their electronic card catalogs for free search. Enormous CD-ROM catalogs are increasingly available trough this service. And there are fantastic amounts of free software available. Any computer of sufficient power is a potential for the Internet, and today such computers seli forless than $2,000. The network is spreading exponentially. It resembles the spread of personal computing in the 1970s, though it is even faster and perhaps more important. How does one get access to the Intenet? Well, if you do not have a computer and a modem, get one. Your computer can act as a terminal, and you can use an ordinary telephone line to connect to an Internet-linked machine. These slower and simpler adjuncts to the Intenet can provide you with the netnews discussion groups and your own e-mail address. If you are on a campus, your university may have direct "dedicated access" to high-speed Internet TCP/IP lines. Apply for an Internet account on a dedicated campus machine, and you may be able to get those long-distance computing and file-transfer functions. Businesses increasingly have Internet access, and are willing to sell it to subscribers. As the Nineties proceed, finding a link to the Internet will become much cheaper and easier. Its ease of use will also improve. Learning the Internet now, or at least learning about it, is wise. By the rum of the century, "network literacy," like "computer literacy" before it, will be forcing itself into the very texture of your life.
