What is the difference between hub and switch:
Hub could be a networking devices that is employed to transmit the signal to every port (except one port) to reply from that the signal was received. Hub is operated on Physical layer. during this packet filtering isn’t obtainable. it’s of two types: Active Hub, Passive Hub.
Switch could be a network device that is employed to modify the affiliation institution and affiliation termination on the idea of would like. Switch is operated on electric circuit layer. during this packet filtering is out there. it’s variety of full duplex transmission mode and it’s additionally known as economical bridge.
Type of hub:
Active Hub:- These are the hubs that have their own power offer and may clean, boost, and relay the signal in conjunction with the network. It serves each as a repeater further as a wiring center. These are accustomed extend the most distance between nodes.
Passive Hub :- These are the hubs that collect wiring from nodes and power offer from the active hub. These hubs relay signals onto the network while not cleansing and boosting them and can’t be accustomed extend the gap between nodes.
Similarities between hub and switch:
A switch have a many port bridge with a buffer and a style that may boost its efficiency and performance. A switch may be a electrical circuit layer device. The switch will perform error checking before forwarding information, that makes it terribly economical because it doesn’t forward packets that have errors and forward sensible packets by selection to the proper port solely. In different words, the switch divides the collision domain of hosts, however broadcast domain remains constant.
A hub is largely a multiport repeater. A hub connects multiple wires returning from completely different branches, for instance, the connection in topology that connects completely different stations. Hubs cannot filter information, therefore information packets ar sent to all or any connected devices. In different words, the collision domain of all hosts connected through Hub remains one. Also, they are doing not have the intelligence to search out out the simplest path for information packets that ends up in inefficiencies and wastage.
