Explanation:
Switches inspect incoming frames at Layer 2, using an internal MAC address table to forward data directly to the target port rather than broadcasting it to all ports.

Explanation:
A network hub acts as a simple Layer 1 repeater, broadcasting incoming data to all connected ports and placing them in a single collision domain.
