What Is A Network Switch?

This article is intended to provide you complete information about what is a network switch. Read on the given details to acquire a good deal of knowledge about network switch. We have tried to present the information in a simple language so that readers find the given explanation of network switch easy to understand.

A network switch is defined as a small sized computer networking device which is used to connect together various segments of a network.

In other words, the explanation of network switch can be put together as a hardware device used to connect multiple numbers of computer systems to a local area network, LAN.

In terms of technical language, a network switch functions at second layer which is called as the Data Link Layer of the Open Systems Interconnection model, OSI model.

An important fact to know about network switch is that it appears quite same to another computer hardware device, called as the network hubs. However, there is a significant difference between these two devices. A network switch usually functions more intelligently and is slightly more costly than a hub.

Here is some useful network switch info, providing more clear explanation of network switch. A network switches is competent enough to examine the data packets when they are received, thus able to figure out the source and destination device of each data packet, and forwarding them appropriately. The benefit of this feature of a computer network is that by delivering messages only to the connected device intended, a network switch preserve network bandwidth and present a better performance than a hub.

There are various models of network switches which are implemented to support conflicting numbers of linked devices. The majority of consumer-grade network switches offer either four or eight connections for Ethernet devices. It is also possible to connect various numbers of switches to one another by a method named as Daisy Chaining to add progressively larger number of devices to a Local Area Network.

We hope that the above presented review helps you find suitable answer regarding what is a network switch by presenting easy to understand explanation of network switch.
