Basic functions of switches Apr 14, 2017

Basic functions of switches:

1. Like hubs, switches provide a large number of ports that can be connected to cables, which can be routed by star topology.

2. Like repeaters, hubs, and bridges, when it forwards frames, the switch generates a distorted square signal.

3. Like a network bridge, switches use the same forwarding or filtering logic on each port.

4. Like the network Bridge, the switch divides the LAN into multiple conflict domains, each conflict domain has the independent broadband, thus greatly enhances the LAN bandwidth.

5. In addition to the features of bridges, hubs, and repeaters, switches provide more advanced functionality such as virtual local area network (VLAN) and higher performance.
