The incorrect match (when n > 1) is

The incorrect match (when n > 1) is Correct Answer MIMD Model of computer : n control units and 1 ALU

Concept:

SISD:

  • SISD stands for single instruction, single data
  • SISD is a uniprocessor machine capable of executing a single instruction, which operates on a single data stream.
  • Von Neumann computer architecture is SISD


SIMD:

  • SIMD stands for Single Instruction, Multiple data
  • A single operation executes simultaneously on multiple elements of data.

MIMD:

  • MIMD stands for multiple instructions, multiple data
  • Separate instruction streams, each with its own flow of control, operate on separate data.


MISD:

  • MISD stands for multiple instructions, single data
  • In MISD many functional units perform different operations on the same data.


Analysis:

​SISD Model of computer: 1 control unit and 1 ALU (Correct)
SIMD Model of computer: 1 control unit and n ALUs (Correct)
MISD Model of computer: n control units and n ALUs (Correct)
MIMD Model of computer: n control units and 1 ALU (Incorrect) because it requires n-control units and n-ALUs.
