To connect a computer with a nearby device in the same room (short distance, point-to-point), which option is most appropriate?

Introduction / Context:
Short-distance connections inside a room are typically direct, simple, and point-to-point—think computer-to-instrument or computer-to-printer cabling. The goal is to select the option that best characterizes this local connection style.

Given Data / Assumptions:

• Endpoints are in the same room (meters apart).
• No carrier services or satellite links are needed.
• Point-to-point dedicated connectivity is intended.

Concept / Approach:

A 'dedicated line' in this context denotes a private, exclusive link between two devices. Although the physical medium may be coaxial, twisted pair, or USB, the defining property is the direct dedicated connection, not a shared or carrier-provisioned service. Ground stations are satellite infrastructures and are irrelevant for in-room links.

Step-by-Step Solution:

Verification / Alternative check:

Common lab setups use direct dedicated cabling (USB/serial/Ethernet patch) between a computer and a device in the same room, matching the dedicated-line concept.

Why Other Options Are Wrong:

A coaxial cable: Possible physical medium, but the broader, more accurate choice is a dedicated line.

A ground station: Satellite infrastructure; irrelevant indoors.

All of the above: Incorrect; ground station is not applicable.

None of the above: Incorrect because a dedicated line is appropriate.

Common Pitfalls:

Confusing the concept (dedicated link) with a specific cable type; many media can implement a dedicated line.

Final Answer:

A dedicated line
