D Correct answer
Explanation

This mode creates three byte long instructions and first byte contains the operation to be performed and second and third bytes contain the address in memory in 8085 processor.

Multiple choice

Which of the following do not have kernel intervention?

  1. Shared memory

  2. Message passing model

  3. Both (1) and (2)

  4. All of these

  5. None of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

In the shared-memory programming model, tasks share a common address space, which they read and write asynchronously. So here there is no kernel intervention unlike Message passing model, where message are send and recieve via kernel only.
