Ethernet Products
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
Switches
The function of a switch is to connect separate networks together.
A Switch maps the Ethernet addresses of the nodes residing on
each network segment and then allows only the necessary traffic
to pass through. When a packet is received by the switch, the
switch determines the destination and source segments of a
packet and forward it to the right direction or drop it if the
destination and the source are originated from the same network.
Switches also prevent bad or misaligned packets from spreading
