Understanding Threads and Multithreading

What is a thread?

• A process that runs independently

• The smallest unit of CPU scheduling

• A type of program

• A kernel component

Which of the following is an advantage of using threads?

• Increased parallelism

• Higher memory consumption

• Reduced system efficiency

• Slower execution

What do threads within the same process share?

• Registers

• Stack

• Address space

• Program counter

Which of the following is unique for each thread?

• Code section

• Heap memory

• Stack

• Data section

What is multithreading?

• Running multiple processes concurrently

• Running multiple threads within the same process

• Using multiple CPUs to execute a program

• Executing a program in batches

Which of the following is a disadvantage of multithreading?

• Increased CPU utilization

• Faster execution

• Difficulty in debugging

• Better responsiveness

In multithreading, which components run concurrently?

• Multiple threads within the same process

• Multiple processes only

• Multiple threads in separate processes

• None of the above

Which of the following is a potential issue with multithreading?

• Deadlocks

• Increased system speed

• Lower CPU usage

• Better memory management

What is a key advantage of multithreading?

• Increased system power consumption

• Reduced memory efficiency

• Improved performance and responsiveness

• Higher process creation overhead

User-level threads are managed by:

• Operating system kernel

• User-level thread library

• CPU scheduler

• Device driver
