A set of elementary operations that can be performed by a CPU is called:

Question

Options

• Aan instruction list
• Ba binary code
• Cthe ASCII code
• Dan assembly order

• A
  79% (31)
• B
  8% (3)
• C
  3% (1)
• D
  10% (4)

Explanation

Option A is correct because a CPU's instruction list (also called an instruction set) defines the complete set of elementary operations - such as ADD, LOAD, or JUMP - that the processor can execute directly in hardware.

Why the distractors are wrong:

• B (binary code) refers to the representation of data/instructions as 0s and 1s - it's the encoding format, not the set of operations itself.
• C (ASCII code) is a character encoding standard mapping letters and symbols to numbers; it has nothing to do with CPU operations.
• D (assembly order) is a nonsense term - assembly language uses mnemonics to represent instructions, but "assembly order" isn't a standard concept.

Memory tip: Think of the instruction list as a CPU's menu - just as a restaurant menu lists everything the kitchen can make, the instruction list enumerates every operation the CPU knows how to perform.
