Switch:
- A Switch is a Networking device, which can perform error checking before forwarding data.
- When a packet comes through a switch it is read to determine which Computer to send the data i.e. one computer will be the sole receiver of the package. This lead to increase efficiency in that packets are not going to computers that do not require them.
- usually large networks use switches instead of Hubs to connect computers within the same subnet.
- Switches can support both layer 2 (based on MAC Address) and layer 3 (based on IP Address) depending on the type of switch.
- when A Switch is compared to bridge, it has multiple ports.
