Synchronization Tools in Concurrent Systems

What is a synchronization tool used to control access to common resources in a concurrent system?

a) thread
b) pipe
c) semaphore
d) socket
Final answer:

Answer:

The correct answer is c) semaphore.

When it comes to concurrent systems, synchronization tools play a crucial role in controlling access to shared resources. One of the commonly used synchronization tools is a semaphore. Semaphores help in preventing race conditions and ensuring that only one process can access the shared resource at a time.

A semaphore works by maintaining a count for the available resources. When a process wants to access the shared resource, it must decrement the semaphore count. If the count is zero, the process will be blocked until the count becomes greater than zero.

By using semaphores, developers can efficiently manage resource access and avoid conflicts in concurrent systems. It is an essential concept in operating systems and parallel programming.
