Switches work at layer two and help improve network speed. The offer a low cost way to grow a network and connect multiple PC. Switches have a lower latency as compared to routers in forwarding traffic. Lower latency because the router need to read the layer 3 network address and the switch will make forwarding decisions based upon layer 2 address (Hyperactive ).

  Hubs in larger networks tend to cause collision. With switching, each connection gets "dedicated bandwidth" and can operate at full speed. In contrast, a hub shares bandwidth across multiple connections such that activity from one PC or server can slow down the effective speed of other connections on the hub. 


Virtual LANSs are made up of software switches and offer faster speeds and administrative benefits (no configuration when user has changed locations). They also control broadcast.

The old name for switches was a bridge. What has changed is the number of ports have increased.
