             When you select a network card, consider the following three factors:
             1. type of network (for example, Ethernet, Token Ring, or FDDI)
             2. type of media (for example, twisted-pair, coaxial, or fiber-optic cable)
             3. type of system bus (for example, PCI or ISA)
             Some of the factors that determine throughput and bandwidth include the following:
             · type of data being transferred
             · power and weather-induced outages
