What does PC stand for in computer hardware?

• A. Peripheral Component Interconnect
• B. Personal Computer
• C. Post Office Protocol
• D. Power Supply Unit

Answer: (B)

In computer hardware terminology, PC stands for Personal Computer—the standalone system used by an individual, such as a desktop or laptop. The other terms refer to different things: Peripheral Component Interconnect is a motherboard bus standard for expansion cards, Post Office Protocol is for retrieving email, and Power Supply Unit is the internal component that powers the system (usually abbreviated PSU). Therefore, Personal Computer is the correct meaning.
