On a LAN, a hub is a device that broadcasts the information it receives to all connected devices. Unlike switches, which intelligently forward data to specific devices based on MAC addresses, hubs send incoming data packets to all ports, regardless of the intended recipient. This can lead to increased network traffic and potential collisions, making hubs less efficient compared to modern networking devices.
Any device on a LAN is called a node.
A communication device is a peripheral used for communication between the computers and other devices. Modem is a popular communication device which is normally used for Internet communication. Infrared, Bluetooth and LAN card are the examples of communication devices.
