The traditional type of Ethernet, in which all hosts are connected to the same bus and compete with one another for bandwidth. In contrast, a switched Ethernet has one or more direct, point-to-point connections between hosts or segments. Devices connected to the Ethernet with a switch do not compete with each other and therefore have dedicated bandwidth.
