Digital concepts — Classification: “a microcomputer is not a general-purpose computer.” Decide whether this statement is accurate or inaccurate, considering that many single-chip and personal computers are designed to execute many kinds of programs and tasks.

Difficulty: Easy

Correct Answer: Incorrect

Explanation:


Introduction / Context:
A microcomputer is a computer built around one or more microprocessors. The question asks whether such a machine is “not general-purpose,” which probes the difference between general-purpose and special-purpose computing in digital electronics and computer architecture.


Given Data / Assumptions:

  • “General-purpose” means capable of running a wide variety of programs to perform many tasks.
  • Microcomputers include personal computers and single-board computers built on microcontrollers or microprocessors.
  • Embedded systems sometimes use microcomputers but may be configured for a single dedicated task.


Concept / Approach:
General-purpose vs. special-purpose is about programmability and breadth of tasks, not the physical size or the presence of a microprocessor. If the hardware can execute arbitrary software within its resource limits, it is general-purpose. PCs and SBCs are clear examples.


Step-by-Step Solution:

Identify definition: general-purpose = runs many types of programs.Map to microcomputers: PCs, laptops, Raspberry Pi boards are microcomputers and clearly general-purpose.Differentiate embedded controllers: some are configured for one task, but the underlying microcomputer is still programmable.Conclude the blanket statement “not general-purpose” is inaccurate.


Verification / Alternative check:
Consider software variety: operating systems, compilers, and applications run on microcomputers, proving general-purpose capability.


Why Other Options Are Wrong:

Correct: contradicts the broad programmability of microcomputers.Only true for early 8-bit systems / embedded controllers: many of those also ran multiple programs; the statement is too sweeping.Depends solely on clock speed: capability is not defined by frequency alone.


Common Pitfalls:
Equating “embedded use” with “special-purpose hardware.” The same microcomputer can be configured either way.


Final Answer:
Incorrect
