1. Like a hub, a switch provides a large number of ports for cable connection and can adopt star topology cabling.
2. Like Repeaters, hubs and Bridges, when it forwards frames, the switch will regenerate a square electrical signal.
3. Like a bridge, a switch uses the same forwarding or filtering logic on each port.
4. Like a bridge, a switch divides a local area network into multiple collision domains, each of which has its own independent broadband.
5. In addition to the functions of a bridge, hub and repeater, a switch also features a virtual local area network (VLAN) and higher performance.
