Questions and Answers

What is the main difference between a process and a thread?

  • threads share the same memory, while processes do not. (correct)
  • Threads take advantage of multiple CPUs and cores, while processes do not.
  • Processes are great for I/O-bound tasks, while threads are not.
  • Starting a process is faster than starting a thread.

    • Which of the following is a key advantage of using threads?

  • Separate memory space
  • Takes advantage of multiple CPUs and cores
  • Light weight with low memory footprint (correct)
