What Hardware Do I Need to Build a Network?

Networks vary in requirements depending on what you wish to accomplish. This ranges from simple file sharing between two computers to a multiple computer setup involving network interface cards, switches, hubs or routers, and cabling or wireless equipment.

Wired Direct Networks

The minimum requirement for a network is two computers, each with a network interface card and one special type of wire called a crossover Ethernet cable.

Wireless Direct Networks

Two computers can be connected together using wireless network cards in each computer. This network is limited to sharing files between the two computers.

Router Networks

Although a hub or switch will work, the most effective method is a router connecting two or more computers. The router can be wired or wireless depending on the network cards in the computers.

Considerations

As the type of networking increases in complexity from a direct network through hubs or switches to a full router network, the cost and installation complexity increases.

Warning

Wireless networks must be managed with the highest available encryption services. Otherwise, neighbors or even people with laptops in automobiles can eavesdrop or access your network.
