An Ethernet hub is a piece of
hardware that connects multiple computers or devices to form a network. An
Ethernet hub is obsolete and has been replaced by a network switch. There are
also some special cases where a hub is advantageous for a switch, although no
reason to use a hub, rather than a switch belong to a typical network.
An Ethernet hub normally use the RJ-45 connector on a
CAT5 Ethernet cable, but they can also use other existing connectors (former).
Simply plug one end of the Ethernet cable into the Ethernet port of your
computer and the other end into the Ethernet port on the hub.
An Ethernet hub typically includes Ethernet ports 4 or 5. But you can also find Ethernet hubs with 6, 8 or 16 Ethernet ports. You can also connect an Ethernet hub to other hubs, routers and switches.
A hub is a relatively simple device. A hub receives a signal from a computer on the network and re-broadcasts that signal to all other computers and devices connected to the hub. A hub is capable of detecting data collisions in the network and then transmit a jam signal to all network ports. For a 10-megabit per second network speed, you can attach up to 4 axes to another, and two hubs can be connected by a 100 megabit per second network speed.
In addition to detecting collisions some hubs are able to resolve network problems. These centers can detect whether a particular port or excessive chatter collisions. When using a hub network speed is limited by the slowest device connected to the hub. For example, if an old computer with a 10 megabit per second network card is connected to a 10/100 megabit per second speed of the entire network hub is 10 megabits per second. Speed dual hub overcome this problem and function at 10 and 100 megabits per second.
Shafts have been replaced by switches.
