It aws standardised as IEEE 802.3. The term "Ethernet" concept of the ether. This became a popular way of connecting computers to enable data sharing and to access devices such as printers.

Ethernet has defferent dervations; the original was designed as 10 base 5 -10 and s for 10MBs, base is the baseband communication used, and 5 stands for 500 ,etres, the maximum distance of communication between the machines. Fast Ethernet or 100 BASE -t gives transmission speeds of 100MBps. Gigabit ethernet is a newer version, which provides speeds of 10 to 100 Gigabits per secound.
