A hub?
by:Geekdout.net
A hub is a relatively small piece of hardware that is used in
conjunction with a computer network. On the back, it includes several
Ethernet ports in which the networked computers are plugged into.
Installation is extremely easy in that you simply plug your existing
router into the back of the hub and then proceed to plug in the
remaining computers. The IP addresses of the computers that are
connected to the hub are assigned by the router it is connected to, not
by the hub. Hubs work by broadcasting all incoming information to every
computer that is connected to it. If a PC makes a request, the hub
retrieves the information and sends that information to every PC it is
connected to until it is notified that the information was received by
the intended PC. The one major downside to the use of hubs in any PC
network is that bandwidth is split amongst the computers that are
connected. If the hub is a 10/100mbps hub and 2 computers are
connected each PC would have a maximum connection speed of 50mbps.
However if 4 PCs are connected the max speed would be 25mbps.
