Consider the following statements about user level threads and kernel level threads. Which one of the following statements is FALSE?
  • a)
    Context switch time is longer for kernel level threads than for user level threads
  • b)
    User level threads do not need any hardware support
  • c)
    Related kernel level thread can be scheduled on different processors in a multiprocessor system
  • d)
    Blocking one kernel level thread blocks all related threads
Correct answer is option 'D'. Can you explain this answer?
Verified Answer
Consider the following statements about user level threads and kernel ...
  • User level threads are not recognised by operating system, hence do not need any hardware support. Since, user level threads are not recognised by operating system, no separate PCB (Process Control Block) information is to stored. Hence, context switching is faster.  
  • Since, Kernel level threads are like separate processes. So, blocking one thread will not block other threads.
