Ethernet is the most widely used networking technology. Ethernet speed is measured in megabits per second abbreviated as Mbps. Typical speeds for Ethernet include 10, 100 and 1000 Mbps. The 1000 Mpbs speed is also referred to as Gigabit ethernet.

Ethernet is distinguishable but its use of cables. Wireless technologies are becoming more common but Ethernet is still very important because it is fast and secure and most facilities have been wired for Ethernet.

The cable used for Ethernet is referred to as CAT 5 Cable, which can actually be Category 5, 5e or 6 cable.

The ends of the cable are referred to as RJ45 (8P8C) connectors.
