Computer types: Which class of computer was historically designed to be as compact and low-cost as possible for single-user tasks?

Introduction / Context:
Computer systems have traditionally been categorized by size, capability, and cost. The question targets the category engineered for compactness and personal use.

Given Data / Assumptions:

• Era: classical taxonomy (mainframe, mini, micro, super).
• Criterion: compact form factor intended for individual users.

Concept / Approach:

Microcomputers (personal computers) were built around microprocessors, offering compact size and affordability. Minis served departments; mainframes served enterprises; supercomputers maximize performance, not compactness.

Step-by-Step Solution:

Verification / Alternative check:

Examples include desktop PCs, early Apple II, IBM PC—each far smaller than minis/mainframes.

Why Other Options Are Wrong:

• Mini: mid-sized multi-user systems.
• Mainframe: very large enterprise machines.
• Super computer: optimized for peak performance, not compactness.
• None: incorrect because 'Micro computer' fits.

Common Pitfalls:

• Confusing 'mini' with 'micro' due to naming similarity.

Final Answer:

Micro computer.
