FAST ETHERNET

IEEE 802.3 DESCRIBES THE FAST ETHERNET STANDARD.
In case of this fast Ethernet the bit time reduces from 100 n sec to 10 n sec.they always uses the hub.This hub is responsible for good communication.there are two kinds of hub available.They are

• Shared hub
• Switched hub

In shared hub all the incoming signals are logically connected to one another.Here only one station can transmit data at a time.In the switched hub,each incoming frame is buffered on a plug-in-line card.Here all station can transmit at a same time.Different types of cables can be used to improve the speed.
