Concept Check

0/5

In synchronization, what prevents multiple processes from accessing a critical section simultaneously?

Mutual exclusion ensures exclusive access

Mutual exclusion mechanism

Semaphore signaling

Deadlock detection

How does a semaphore handle process synchronization?

By using wait and signal operations

Via memory allocation

With interrupt handling

Through priority scheduling

What is a key feature of Peterson's algorithm?

It achieves mutual exclusion without hardware

Uses hardware instructions

Implements deadlock avoidance

Relies on timers

In the reader-writer problem, how are writers synchronized?

Readers share access

Through message passing

Using spinlocks only

Writers get exclusive access

What distinguishes a spinlock from a mutex?

Mutex prevents starvation

Spinlock is faster in multiprocessors

Mutex uses context switching

Spinlock busy-waits for lock
