Networking Hardware



There are many components involved in computer networking and to enumerate them all would make for a lengthy read. First, let's clarify the difference between a switch, a router and a hub. The basic difference is varying intelligence:

Now, to list a few more network hardware components: "Networking devices may include gateways, routers, network bridges, modems, wireless access points, networking cables, line drivers, switches, hubs, and repeaters; and may also include hybrid network devices such as multilayer switches, protocol converters, bridge routers, proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, ISDN terminal adapters and other related hardware." (Wikipedia)

The most basic piece of networking hardware is the ethernet adapter found at the back of most computers, old and new. These have ports facing outwards in order to be connected to other devices, and there are two kinds of cables utilised in order to do so: coaxial and twisted-pair.
