Which of the following statements is true?
Lilit [14]

Answer:

Option A is the correct answer choice for the above question.

Explanation:

The computer system needs intercommunication which is done inside the processor to process the task given by the user. There are two types of model is used for intercommunication--

  1. Message passing and
  2. Shared memory

The difference between two is that message passing passes the message on two points at a single unit of time whereas shared memory simultaneous shares the multiple messages. That's why shared memory is faster than message passing.

  • Hence option A is the correct choice because it also refers to the above concept. While the other is not correct because--

  • Option C states that message passing is used for large data but shared memory is used for large data.
