Table 4 - Networking Device Types

Description
A Hub is so called because a diagram of its
connections resembles a hub of a spoked
wheel.
Characteristics:
Echoes a message on any port to all other
ports; constitutes a collision domain for all
connected devices.
Isolates the device(s) on a "bad" port.
A Switch is similar in appearance to a Hub, but
connects only the ports specified as Source and
Destination devices in each message packet.
Collision domains are partitioned; that is, they
are isolated to Source/Destination devices.
Extends the distance over which network
traffic can be transported; all message packets
at input port are repeated at the output port (no
domain partitioning). Signals are amplified,
but are not re-shaped or re-timed.
An intelligent Repeater that connects input and
output ports, but only if the message specifies
the device on the output port as the
Destination.
An intelligent Bridge that is often used for
wide area networks (WANs). Usually includes
a computer with its own network address,
memory, and network-based software. It can
be configured to determine which data packets
received will be transferred to a LAN node
based on destination address (such as an
HC900 controller and/or protocol port
number).
A PC set up to inter-connect two disparate
network models at any combination of layers
of the OSI Model.
