Cost, Expandability, Location of Your PC's and speed. This article does not explain every networking type available, but each of the following network types offer a solution that is suitable for the home, has wide industry support and offers a good value for the money. Ethernet is fastest of the network types and can be the least expensive. Ethernet networks are very stable and your network speed will never fluctuate or be prone to interference like other network types are.
Ethernet requires special cables running from each computer.
These cables are plugged into a central 'ethernet hub' or 'switch'. If your computers are far apart, running cable in an existing home may be difficult. Pre- made ethernet cables come in sizes ranging from 3 feet to 50 feet. Ethernet adapters come in many shapes and sizes, but PCI Ethernet cards are both the fastest and least expensive. Ethernet can operate at 10Mbps or 100Mbps.
