so the communication links tend to have a higher speed
and lower error rate than do their counterparts in wide-area networks. The most
common links in a local-area network are twisted pair, coaxial cable, fiber optics,
and wireless connections. Communication speeds range from tens of megabits
per second (for wireless local-area networks), to 1 gigabit per second for Gigabit
Ethernet. The most recent Ethernet standard is 10-gigabit Ethernet.
