What are the key characteristics of 10baseT Ethernet.

A 10baseT Ethernet LAN conforms generally to the IEEE 802.3 standard. Also known as Twisted Pair Ethernet, it has the following key characteristics:

• Transmits at 10 Mbps
• Normally uses UTP cable
• Minimum grade of UTP cable is Category 3
• Typically supports about 12 nodes per hub*
• Uses star or bus topology
• Minimum distance between nodes is 2.5m
• Maximum length of segment is 100m
• Most common type of Ethernet LAN; used in both small and large networks

*There is no hard and fast rule here. Hubs can be connected together so in total a 10BaseT LAN can support up to 1024 nodes without a bridge.
