User’s Guide
The Fast Ethernet contains three different cabling schemes.
100Base-TX for use with category 5 UPT/STP cable,
100Base-FX for use with Multi-mode fiber-optic cable, and
100Base-T4 for use with cable 3,4,or 5 UPT cable. Among
three of them, 100Base-TX is most compatible to 10Base-TX.
It allows users to retain the existing 10Base-T cabling
infrastructure, thus becomes the most popular Fast Ethernet
technology. Gigabit Ethernet is still in the process of
development. Other than supports higher data transfer speed,
this technology also promises for an easy migration path.

Hub
Hub is a central connection point for wiring the network. It
connects two or more Ethernet segments of any media type.
When transmitting signal begins to deteriorate, which is caused
by the limitation of media length, hub simply takes the
incoming signal and repeats or amplifies it out to all ports
connected. Hub, also called repeater, only allows users to
share Ethernet. Individuals of a shared network can only get a
percentage of the available network bandwidth, therefore, a
network of repeaters also named
“
Shared Ethernet
