Question 1

What is a thread in the context of an operating system?

  • A program under execution

  • A lightweight process

  • A type of CPU scheduling

  • A memory allocation method

Discuss it

Question 2

Threads are effective only if the CPU is:

  • Multi-core

  • Single-core

  • Virtualized

  • Idle

Discuss it

Question 3

Which of the following is shared among all threads in a process?

  • Stack

  • Program counter

  • Register set

  • Code section

Discuss it

Question 4

Which component is NOT unique to each thread?

  • Thread ID

  • Program Counter

  • Stack

  • Address space

Discuss it

Question 5

Why are threads needed?

  • To replace processes entirely

  • To improve application performance via concurrent execution

  • To reduce memory usage to zero

  • To make processes share separate address spaces

Discuss it

Question 6

Which of the following is NOT a component of a thread?

  • Stack Space

  • Register Set

  • Program Counter

  • Process Table

Discuss it

Question 7

User-level threads are managed by:

  • The OS Kernel

  • The CPU hardwar

  • Thread libraries

  • The BIOS

Discuss it

Question 8

Which is a disadvantage of user-level threads?

  • Slow context switching

  • Entire process blocks if one thread blocks

  • High kernel overhead

  • Cannot run on single-core systems

Discuss it

Question 9

Kernel-level threads can run on multiple processors because:

  • They are invisible to the OS

  • They share the same stack

  • They don’t require hardware support

  • The kernel schedules them directly

Discuss it

Question 10

Main difference between a process and a thread is:

  • Processes share memory, threads do not

  • Threads share memory, processes do not

  • Threads are heavier than processes

  • Processes are faster to create than threads
