NICs (Network Interface Cards) vary in network topology, network speed and network interface type depending on the environment they are designed to operate in.
The most common topology is Ethernet.
Common speeds are 10Meg/sec, 100Meg/sec, 1Gig/sec, 10Gig/sec
Network Interface types are:
COAX cable, RJ45 cable, Fiber Optic cable, Wireless WiFi
Standards for interface, speed and protocols are defined by the Institute of Electrical and Electronics Engineers.
