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 Internetarchitecture 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 (in buildings, aerial, buried, undersea), infrared, Visible Light Communications (VLC LED-to-LED, low-speed), wireless [Wi-Fi, cellular, point-to-point microwave, WiMax, SuperWi-Fi, satellite, millimeter wave (30-300 GHz)], power lines, etc.Networks come in many sizes and are often interconnected to make larger networks. The Internetis the best know example of a network of networks.Peterson & Davie – “Computer Networks are built primarily from general-purpose programmable hardware, and they are not optimized for a particular application like making phone calls or delivering television signals.
