What is a computer network?Tanenbaum– “A Computer Network is a collection of autonomouscomputers interconnected by a single technology.”“Two computers are said to be interconnected if they are able to exchangeinformation”The most common “single technology” today is theInternetarchitectureIt has not always been like this. In the beginning, their were many different computernetworks ARPANET, DECNET, IBM’s SNA, OSI, etc.The connection may be copper twisted pair (Ethernet, ADSL, VDSL), coax (cablemodem, MoCA), fiber optics (in buildings, 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 largernetworks. TheInternetis the best know example of a network of networks.Peterson & Davie– “Computer Networks are built primarily fromgeneral-purpose programmable hardware, and they are not optimizedfor a particular application like making phone calls or deliveringtelevision signals. Instead they are able to carry many different types ofdata.”Computer Networks do indeed carry phone calls (e.g., VoIP telephone systems7,850 VoIP lines and 8,088 Centrex lines on campus in June 2016, Skype) andtelevision (e.g., the White Creek Apartments on campus have television accessonly via Philo IPTV using a Roku2 or by watching on a computer or smartphone).
