What is a network switch?

A switch is a Network device that is based on MAC that is able to complete the job of encapsulating as well as sending data. The switch is able to "learn" how to recognize the MAC address and then store it in its internal address database. By creating a temporary switching route between the originator and the intended receiver for the frame the data frame will be able to directly get to the destination address directly from the address that originated.
Switch for networks can be described as a switch and its predecessor was a bridge. The switch makes use of hardware to accomplish the job of filtering, learning, and forwarding using bridge software earlier. SWITCH is much faster than HUB. It is because HUB doesn't know which address the target is and therefore sends information to every port. There are routing tables inside SWITCH when it does know the address of the target and sends data to that address, however, if it does not know the address, it will forward the data through all the ports. This filtering could help to reduce the amount of data that is transmitted through the entire network, and increase effectiveness. However, the role of the switch is much more than just that. It is able to break the network into branches, separate the flow of data through the network and separate the faults that affect the branches. This could reduce the information flow through each branch and make the network more efficient. Enhance the effectiveness of the whole network. There is a tendency to use SWITCH in place of HUB.
