A switch is a type of computer network component that is used to connect several HUBs to form a larger computer network or to connect computers that have a large enough transmission capacity.
Some of the functions of this tool are as traffic management found on a computer network, this tool is tasked with how to send packets of information to get to the destination with the right device, this tool is also tasked with finding good and ideal pathways and ensuring the delivery of packet information efficient aim.
How the Switch Works
The switch is the same computer network equipment (hardware) as the HUB, the difference is that this object is smarter even though the price is a little more expensive than the HUB. The way this tool works is by receiving packet information on a port and then will see the destination MAC (Media Access Control) and establish a logical connection with the port that is already connected to the destination hub or device, so that other than the destination port cannot receive the packet information sent and will reduce the occurrence of information collisions or called crashes.
Every device that is connected to a particular port, its MAC addser will be recorded in the MAC address table which will then be stored in the cache cache memory, that’s how this tool works.
Broadly speaking, the Switch function is as a concentrator on a computer network with a star topology, but actually this hardware itself has a main function that is far more complex than just a concentrator. First is as Address Learning. Second is to forward / filter the Data Frame. Third is Circling Avoidance, this one function is useful when an information received is not recognized its purpose, this is usually caused by an error when connecting cables to the ports of this device.
