What is a computer network? Tanenbaum – “A Computer Network is a collection of autonomous computers interconnected by a single technology.” “Two computers are said to be interconnected if they are able to exchange information” The most common “single technology” today is the Internet architecture It has not always been like this. In the beginning, their were many different computer networks ARPANET, DECNET, IBM’s SNA, OSI, etc. The connection may be copper twisted pair (Ethernet, ADSL, VDSL), coax (cable modem, MoCA), fiber optics (aerial, buried, undersea), infrared, wireless (Wi-Fi, cellular, point-to-point microwave, WiMax, SuperWi-Fi, satellite), power lines, etc. Networks come in many sizes and are often interconnected to make larger networks. The Internet is the best know example of a network of networks.
