transmission. |
| 10BaseT |
The most common and easiest type of Ethernet LAN to
install. This type of network uses network hubs and switches with
Cat 5 cabling and RJ-45 connections. Its maximum data transfer rate is
10Mbps. |
| 100BaseT |
Known as Fast Ethernet, 100BaseT has a maximum data
transfer rate of 100Mbps. It uses network devices and Cat5 cabling
rated for the higher speed. |
| Cat 3 |
