Also, most hubs can gather information and report the
information to a host that connects directly to the hub. This monitoring host provides a graphical
interface that displays statistics and graphs.
Many Ethernet adapters today are 10/100 Mbps adapters. 100BaseT, which typically uses category-5
twisted pair (a highquality twisted pair with a lot of twists). Unlike the 10Base2 and 10BaseT,
100BaseT does not use Manchester encoding, but instead a more efficient encoding called 4B5B:
every group of five clock periods is used to send 4 bits in order to provide enough transitions to allow
clock synchronization.
Gigabit Ethernet
Uses both fiber and twisted-pair cooper wire and transmits at a rate of 1 Gbps.
• Uses the standard Ethernet frame format, and is backward compatible with 10BaseT and 100BaseT
technologies. This allows for easy integration of Gigabit Ethernet with the existing installed base of
Ethernet equipment.
