What is a Network Switch?

A network switch is a networking device that connects multiple devices—such as computers, servers, and printers—within a Local Area Network (LAN) and uses MAC addresses to forward data intelligently. Unlike a hub, which broadcasts data to all devices, a switch directs data only to the intended recipient, reducing congestion and improving efficiency.

Common Features:

• MAC address learning and forwarding: Automatically identifies and records device addresses;

• Independent port communication: Ensures fast, collision-free data transmission;

• VLAN support: Allows creation of logical sub-networks for better security and management;

• Remote management (for managed switches): Enables configuration, monitoring, and troubleshooting;

• PoE (Power over Ethernet): Delivers power to devices like IP cameras or wireless APs via Ethernet cables.
