What is Switch and how is it different from Hub?

Do you know what this switch is and what type of network device it is? How does the switch work and what are its Advantages and Disadvantages? If you do not know much about all these things, then you should definitely read this article of today's What is a network switch. Because in this, you will get complete information about everything related to Switch.

A switch is a telecommunication device that is grouped according to a computer network component. Although the Switch is similar to a Hub but it has some built in advanced features. It uses physical device addresses to identify each incoming messages so that it can deliver the message to its correct destination or port.

Like Hub, the switch does not broadcast the received message to the entire network, but before sending any message, it checks that it is sent from the cone to the system or port. In other words, then the switch directly connects the source and the destination, which shows a great increase in the speed of the network. So today I thought why should you people be explained about the Switch in Hindi, which will help you to know it better. So let's start without delay.

Switch is a networking device that helps devices in the network connect with each other, so that they can transfer data into the network. These network switches are completely identical to network hubs, but a switch is more intelligent than a hub.

Intelligence implies that the network switch first inspects the incoming packet, determines its source and destination address and then routes the correct place accordingly to that packet.

This way significantly switches the bandwidth by forwarding the switched packets to the correct destination. If we talk about now, then network switches are now available in 10/100/1000 Mbit / sec as well as 10/100 Gbit / s ports. They operate in layer 2 of the OSI Stack. It is also often understood as a multiport bridge.

What are the methods used by switches?

Switches mainly use 4 methods to forward the packet. So let's know about them further.

1. Store and Forward - In this method, the switches buffer each frame and perform checksum in it before forwarding them.

2. Cut through - In this method, no error check is performed. It mainly reads the hardware address of the switch frame and then forwards it.

3. Fragment Free - Actually this method is nothing but a combination of both methods mentioned above i.e. Store and Forward and Cut through. In this method, the first 64 bytes of the first frame are checked by which the addressing information is received. This lets the switch know about the destination of the frame. Error checking is performed by layer 3 and layer 4 which is typically router of end device.

4. Adaptive switching - This is the last method that is used for automate switching between the remaining three modes.

What are the common features of Switch and Hub

Having multiple RJ-45 ports

Power supply

Connection lights

Type of Switch

Switches are actually connectivity points of an Ethernet network. These are small devices that receive data from multiple input ports and send them to a specific output port that takes that data to the correct destination in that network. You can see many types of switches in the network, let's understand them now

1. Unmanaged Switch

Most of these switches are used in home networks and small businesses as they are plug-in and can be started using them immediately. There is no need to watch these switches nor configure them. These require only small cable connections. This allows devices in the network to connect with each other, such as computer to computer, or computer to printer in one location. When it comes to the price, then it is cheaper than the rest.
