A bus is a communication pathway connectingSelect one:A.two or more devices.B.two internal devices.C.two external devices.D.two remote devices.

Break Down the Problem

1. Identify what a bus is in the context of communication pathways.
2. Analyze each option to determine what types of connections a bus facilitates.

Relevant Concepts

• A bus serves as a link that enables data transfer between multiple devices, allowing them to communicate.
• Buses can connect internal devices within a computer, external devices to a computer, or even facilitate communication between remote devices.

Analysis and Detail

1. Option A: Two or more devices - This definition aligns with the fundamental purpose of a bus, which is to enable communication between multiple devices.
2. Option B: Two internal devices - This is a specific case of communication, but a bus can connect more than just two internal devices, so it is not comprehensive.
3. Option C: Two external devices - Similar to option B, this is too narrow since buses can connect multiple devices regardless of whether they are internal or external.
4. Option D: Two remote devices - This is also a restrictive option, as buses generally connect devices that may not be remote.

Verify and Summarize

The broadest and most correct choice that encompasses all scenarios is Option A because it includes communication pathways that link two or more devices, internal or external.

Final Answer

A. Two or more devices.
