• #5: �� The Internet is a vast collection of inter-connected computer networks connecting computers all over the world. No one knows exactly how many computers are connected to the Internet. It is certain, however, that these number in the millions and are increasing at a rapid pace. ��
• #6: 3 These networks contain special computers that store information and serve it out as needed to those who connect to them. “Serve” is a good word because you might have heard of servers – that’s another name for computers that store information and direct it out to people when they request it. So this network of networks is made up of lots of computers or servers, all over the world, that hold information – and ---
• #7: In spite of the lack of any central control, remarkably, this anarchy by design works exceedingly well. All computers on the Internet communicate with one another using a uniform set of rules which govern the transmitting and receiving of data. This is known as TCP/IP which is an abbreviation for Transmission Control Protocol/Internet Protocol. Computers on the Internet use a client/server architecture. This means that the remote server machine provides files and services to the user’s local client machine. In other words, the computer we are using to access the Internet is the local client which we use to connect to remote servers.
• #8: 4 One way to think of and describe the Internet is a connected community of servers and networks. It is a virtual community, but just as cities and towns are linked together by roads and highways, the virtual “places” on the Internet are linked together by wires, cables and satellite connections. You’ve heard the phrase “Information Superhighway” – that’s a great way to think of it. To carry that analogy even further you might hear about “traffic” on the Internet. Sometimes we hear about servers crashing because of too much traffic—too many people trying to get to the same place at the same time. �� Again, this community is global. It includes servers all over the world, from the United States to Australia – from Greenland to Italy.
