Explanation: 

Detailed explanation-1: -A network switch forwards data packets between devices. Switches send packets directly to devices, rather than sending them to networks like a router does.

Detailed explanation-2: -A network switch is equipment that allows two or more IT devices, such as computers, to communicate with one another. Connecting multiple IT devices together creates a communications network.

Detailed explanation-3: -Hub. A hub is a physical device used to join multiple devices on the same LAN. For example, a laptop, desktop computer and printer can connect into a hub’s ports with Ethernet cables and be part of the same local network.

Detailed explanation-4: -How does a network switch work? Once a device is connected to a switch, the switch notes its media access control (MAC) address, a code that’s baked into the device’s network-interface card (NIC). The NIC attaches to an Ethernet cable that connects to the switch.
