Ethernet Switching - Ethernet Switches

Switched Ethernet is an Ethernet network that is controlled by a switch.  Ethernet is wired in a star configuration with a hub or switch in the middle.

Hubs, which predated switches,
are shared media devices. All stations attached to the hub share the total bandwidth. Switches provide each sender and receiver pair with the full bandwidth and are significantly faster than hubs (see switched Ethernet). Like the client machines, Ethernet switches and hubs also support 10/100 and 10/100/1000 speeds.

The switch cross connects two stations and gives each sender-receiver pair the full bandwidth of the network. The total bandwidth is 20 Mbps or 200 Mbps between nodes for full-duplex operation or 10 and 100 for half-duplex. A major advantage in migrating from shared to switched Ethernet is that only the hub is replaced with an Ethernet switch. The existing network adapters (NICs) in every computer connected to the switch are still valid.

A 10/100 Ethernet port supports two speeds: 10 Mbps (10BaseT) and 100 Mbps (100BaseT).

Computers also come with 10/100/1000 ports, which adds Gigabit Ethernet at one gigabit per second. Gigabit Ethernet (GigE) is commonly used as a high-speed link between switches and servers. Ethernet devices negotiate with each other and transmit at the highest speed possible. However, if a 100 Mbps switch is communicating with a 10 Mbps client, the slower speed is used.
