A technician is comparing two laptop accessories: one connects via a single proprietary port and provides full video, network, and multiple USB expansion, while the other simply duplicates the laptop's native ports through a single cable. Which accessory offers the full expansion capability?
- AUSB hub
- BPort replicator
- CDocking station
- DKVM switch
Show answer & explanationAnswer & explanation
Correct answer: C. Docking station
A docking station provides extensive expansion, including additional video outputs, Ethernet, and multiple USB ports, often exceeding the laptop's native port set. A port replicator simply mirrors the laptop's existing ports without adding extra functionality.
Why the other options are wrong
- A. A USB hub only expands USB connections, not video or network capability.
- B. A port replicator only duplicates existing native ports, not full expansion.
- D. A KVM switch allows one keyboard/video/mouse to control multiple computers, unrelated to port expansion.
Docking Station vs Port Replicator
A docking station adds extra ports and capabilities beyond the laptop's native connections, while a port replicator simply duplicates existing native ports.
- Docking stations often add extra video outputs and Ethernet
- Port replicators are simpler and cheaper
- Both connect via a single proprietary or USB-C connector
Memory trick: Docking stations 'dock' extra features; replicators just 'replicate' what's there.
