Switching
Messages are sent over the network of transmission media when a person uses the internet or another computer network from a location other than their immediate area. Switching is the term used to describe this method of moving data between computer networks.
Switch Concepts and Configuration
A switch is a discrete piece of hardware that connects various computers to a single local area network (LAN). In the OSI model, network switches function at layer 2 (Data link layer).
- On the basis of MAC addresses, switches are utilized to forward the packets.
- The switch makes it possible for the device that has been addressed to receive the data.
- It checks the destination address before properly routing the packet.
- Full duplex operation is used.
- Since the source and destination are communicating directly, packet collision is minimal.
- It does not broadcast the message since its bandwidth is constrained.
