A network is a set of devices, software, and cables that enables the exchange of information between them. Host devices are computers, servers, laptops, Personal Digital Assistants (PDAs), or anything a person uses to access the network. Network devices are hubs, repeaters, bridges, switches, routers, and firewalls (to name a few). Cables can be copper, fiberoptic, or even wireless radio (which isn't really a cable, but serves the same purpose). The applications used on a network include those that actually enable network connectivity, such as the Transmission Control Protocol/Internet Protocol (TCP/IP) protocol, those that test network links, such as the Internet Control Message Protocol (ICMP), and end-user applications, such as email and File Transfer Protocol (FTP). There are thousands of networkable applications; we are concerned with a small number of them.
