1. Like a hub, the switch provides a large number of ports for cable connections, allowing for star topology routing.
2. Like repeaters, hubs, and bridges, when it forwards a frame, the switch regenerates an undistorted square electrical signal.
3. Like a bridge, the switch uses the same forwarding or filtering logic on each port.
4. Like a bridge, a switch divides a LAN into multiple collision domains, each with independent broadband, thus greatly increasing the bandwidth of the LAN.
5. In addition to the capabilities of bridges, hubs, and repeaters, the switch provides more advanced features such as virtual local area networks (VLANs) and higher performance.
