The difference between hub, switch and router
1. Hub : 1.A Hub A Hub is just a connector that connects the wires coming from different sides. There is no signal processing or regeneration. It is an electronic device that operates only on physical layers of the OSI model. It is also known as a repeater as it transmits signal to every port except the port from where signal is received. Also, hubs are not that intelligent in communication and processing information for 2nd and 3rd layers. 2. Switch Switch is a point to point communication device. It operates at the data link layer of OSI model. It uses switching table to find out the correct destination. Basically, it is a kind of bridge that provides better connections. It is a kind of device that set up and stop the connections according to the requirements needed at that time. It comes up with many features such as flooding, filtering and frame transmission. 3. Router : Routers are the multiport devices and more sophisticated as compared to repeaters and bridges....
