A general-purpose, single-user microcomputer designed for operation by one person at a time is commonly referred to as what?

Introduction / Context:
Computing devices are categorized by purpose (general vs special), scale, and usage model (single-user vs multiuser). The most common category for everyday individual use is the personal computer, a general-purpose, single-user system capable of running a wide range of applications.

Given Data / Assumptions:

• The system is general-purpose (not limited to a single application).
• It is designed for one user at a time.
• We must select the standard industry term.

Concept / Approach:
The term ‘‘PC’’ (Personal Computer) denotes a general-purpose single-user microcomputer. It typically includes a CPU, main memory, mass storage, I/O devices, and an operating system for interactive use. This is distinct from special-purpose computers, which are tailored to specific tasks or embedded applications.

Step-by-Step Solution:
Match the description to terminology: single-user + general-purpose = personal computer.Eliminate distractors: special-purpose is not general; ‘‘KIPS’’ refers to performance metrics (thousand instructions per second); ‘‘M’’ is not a standard device class.Therefore select PC (Personal Computer).

Verification / Alternative check:
Industry usage, textbooks, and vendor literature consistently apply ‘‘PC’’ to desktop and laptop systems intended for one user at a time.

Why Other Options Are Wrong:

• Special-purpose computer: Not general-purpose.
• KIPS: A throughput metric, not a device type.
• M: Not a recognized class in this context.
• None of the above: Incorrect because ‘‘PC’’ fits exactly.

Common Pitfalls:
Confusing performance metrics or shorthand letters with standard system categories. Focus on the functional description.

Final Answer:
PC (Personal Computer)
