Explain the difference between hub and switch in term of traffic management.
thank you for time and effort

Answer 1

Hub: Hub transfers the info or data to every port. e.g If there are 4 computers connected by a hub and A sends data to the hub, it is sent to every connected computer. Whoever is the receiver, receives the data/info and the other computer ignores the info/data. It doesn't store the addresses of the ports. There is no control or security on data/info. Data or info flows freely to every port. It works on layer 1 of the OSI model i.e. physical layer. It is usually used to connect ethernets to work as a single unit.

Switch: switch has better traffic management than the hub. Switch knows the address of every port. So if any data or info arrives at it, it read the destination address of that info/data and sends info/data to that address. So there is one to one connection(kind of). Switches are usually used to connect different computers using LAN. There is restrictions on data flow, It flows only in one direction and reaches only its destination. A switch is part of the data link layer. Switches know mac addresses of each computer that is connected to it
