The Difference between Hubs and Switches

Ethernet "hubs" and "switches" are both used for networking workstations, file servers, printers, and many other components (each of which is referred to as a 'node' of the network). The main difference between hubs and switches is the way in which the nodes communicate with the network.
There are advantages and disadvantages to both, and which one you use will depend on the size of your network, the amount of traffic that it handles, and its purpose.

Hub
A common connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports. When a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.

Switch
In networks, a device that filters and forwards packets between LAN segments. Switches operate at the data link layer (layer 2) and sometimes the network layer (layer 3) of the OSI Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs.

differentiate wired and wireless communication. differentiate co-channel and adjacent channel interference.
