Switches allow different nodes (a network connection point, typically a computer) of a network to communicate directly with one another in a smooth and efficient manner. Â­There are many different types of switches and networks.
1 Using a switch is calledmicrosegmentation. 2  This allows computers to have dedicated bandwidth on apoint-to-point connection to the network and to therefore run in full duplex withoutcollisions.Role of Switches in NetworksSwitches may operate at one or more layers of the OSI model, including data link andnetwork.
