Question

Which of the following statement is true for concurrency?

(a) different parts of the program executes physically

(b) different parts of the program executes sequentially

(c) different parts of the program executes conceptually

(d) different parts of the program executes sequentially and physically

The question was posed to me in an internship interview.

This is a very interesting question from Types of Processors topic in division Embedded Processors of Embedded Systems

Answer 1

The correct choice is (c) different parts of the program executes conceptually

To elaborate: A concurrent program executes different parts of the program conceptually, a parallel program executes different programs physically and a non-concurrent program executes the program in sequential order.
