RRB ALP 2025 CBT 2 Mechanic Motor Vehicle Question Paper (28-Jul-2026) (Shift 1)
The correct answer is

Central Processing Unit

The question asks what CPU stands for in computing, with multiple options provided. Let's analyze each of the options to determine the correct answer:

  • Computer Processing Unit: This term is incorrect as there isn't a standard concept or component named Computer Processing Unit in computer architecture.
  • Core Processing Unit: While cores are parts of a CPU, there is no separate component referred to as a Core Processing Unit.
  • Central Processing Unit: This is the correct answer. The CPU, or Central Processing Unit, is the primary component of a computer that performs most of the processing inside a computer. It executes instructions from a computer program and is often referred to as the computer's brain.
  • Control Processing Unit: Similar to the first option, this term does not exist within standard computer architecture terminology.

Since the CPU is vital for a computer's operation, understanding its role is crucial for theoretical and practical examinations. The CPU fetches, decodes, and executes program instructions, playing a key part in computer operation. Thus, the term Central Processing Unit is universally accepted and used in the field of computing.

Conclusion: The correct answer is Central Processing Unit.
