The internet

It may eventually be a backbone for the so-called data superhighway, or it may become the equivalent of route 66 in American highway history, bypassed by nevwer and wider roads. The highways will probably consist of computer networks, wholesale replica designer handbags, able TV, interactive phone services and other technologies.
What can I find on the internet?
If you can imagine it, you can probably find it. You can check the card catalogue of the library of congress, retrieve free software, get the latest news, send and receive electronic mail, wholesale designer handbags, complain about the mets with fellow sufferers, view nasa satellites images, reach the world’s leading authorities on pandas, and so on. The are literally thousands of “interest groups” on the net.
Finding things in such a vast supply of data, however, is not easy. There is no complete road map or directory. Part of the fun is exploring.
What do I need to get onto the internet?
For now, the requirements are a personal computer, a device called a modem, a communications program, access to a telephone line and an account with an internet wervice provider. The computer does not have to be too fancy, although the ability to use windows software or the Macintosh operation system is a definite. A speed of 14, 400 bits is ok but a faster one, 28.8 or 56 KBPS is better.
What is my first step in getting onto the internet? Guide. There are at least two dozen of them out there now. or ask a computer literate friend to show you how to use the “net”.
Who owns the internet?
Nobody owns it. It is a cooperative but often chaotic federation of independent net works. Some regulatory groups set standards for the way the information flows over the internet, wholesale coach handbags, but they are not too effective at present.
