Unit 2 Summary Quiz

In a multithreading environment, which of the following is a challenge associated with thread scheduling?

• Ensuring thread synchronization and avoiding race conditions
• Allocating a unique address space to each thread
• Minimizing the number of processes
• Increasing the size of thread stacks

In multithreading, what is a primary advantage of having multiple threads within a single process?

• Improved application performance and responsiveness
• Increased memory usage
• Simplified code complexity
• Reduced number of processes

In thread programming using Pthreads, which function is used to create a new thread?

• pthread_create()
• pthread_begin()
• pthread_start()
• pthread_new()

What is the primary purpose of a process in an operating system?

• To manage hardware resources
• To execute a sequence of instructions
• To store user data
• To manage system tasks and operations

What is the role of process control in an operating system?

• To manage hardware interrupts
• To handle the creation, execution and termination of processes
• To oversee thread execution
• To allocate system memory

What does the Round Robin (RR) scheduling algorithm do?

• Cycles through processes, giving each a fixed time slice
• Allocates CPU based on process priority
• Executes processes in the order they arrive
• Selects the process with the shortest burst time

What distinguishes a thread from a process?

• Threads are isolated from each other, while processes share resources.
• Threads share the same memory space, while processes do not.
• Threads have their own memory space, while processes share resources.
• Threads cannot interact with each other, but processes can.

What does process creation involve?

• Allocating memory for the process
• Deallocating resources
• Freezing process execution
• Transferring control to another process

What happens during process termination?

• The process is suspended and put into the ready queue
• The process's resources are deallocated and it is removed from the system
• The process is transferred to a different system for execution
• The process is moved to the waiting state for additional resources

What is a common feature of cooperative multithreading?

• Threads voluntarily yield control to allow other threads to execute
• Threads are preemptively interrupted by the scheduler
• Threads are executed in strict priority order
• Threads cannot share resources with each other
