Explanation:
Because a hub lacks forwarding logic, it repeats incoming data to all ports, creating a single shared collision domain that reduces performance.
Which networking device operates at the Data Link Layer (Layer 2) and uses MAC addresses to filter and forward data packets only to the specific destination port?
Explanation:
A network switch is an intelligent Layer 2 device that learns MAC addresses and routes traffic exclusively to the intended device, unlike a hub which broadcasts to all ports.
