Switches are another fundamental

Switches are another fundamental part of many networks because they speed things up. 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.

There are many different types of switches and networks. Switches that provide a separate connection for each node in a company's internal network are called LAN switches. Essentially, a LAN switch creates a series of instant networks that contain only the two devices communicating with each other at that particular moment. In this article, we will focus on Ethernet networks that use LAN switches. You will learn what a LAN switch is and how transparent bridging works, as well as about VLANs, trunking and spanning trees.

A switch is a device that allows many computers to connect with one Internet connection. In 1990 Kalpana introduced the first Ethernet switch. The switch transmits data at Ethernet standard rates, connecting the computers together. This connection is done inside an existing Local Area network (LAN).

When a data packet is received by the Ethernet switch, it reads the address and proceeds to create a temporary connection between both the addresses. Next the data packet is routed to the appropriate destination and the connection is terminated.

Both the Ethernet hub and the Ethernet switch are used for the purpose of computer networking. Basically switches are devices that can recognize, read, inspect and filter the data packets; hubs are repeaters and do not do any processing. A switch is much better compared to the hub, as it is faster, modern and more intelligent.
