A switch is a networking device that connects multiple devices on a LAN and forwards data only to the device that needs it.
Why it matters:
- Improves efficiency compared to old “hubs” that broadcast traffic everywhere.
- Essential for businesses with many connected devices.
- Smart switches can prioritize certain traffic (like voice or video).
Pro tip: If you’re running out of Ethernet ports on a router, adding a switch is the best solution.
