Explanation
A switch is the direct, modern replacement for a hub. Both are used to connect multiple devices on a LAN, but a switch is far superior: it uses MAC address tables to forward frames only to the intended destination port (rather than broadcasting to all ports like a hub), provides each device with dedicated bandwidth, and supports full-duplex communication. This eliminates collisions and dramatically improves network performance. Firewalls, modems, and bridges serve entirely different primary functions.
