To answer this question, we need to understand the concept of synchronization in the context of threads.
Synchronization is a mechanism used in concurrent programming to control the access to shared resources by multiple threads. It ensures that only one thread can access a shared resource at a time, preventing data inconsistencies and race conditions.
Let's go through each option to understand why it is correct or incorrect:
Option A) the delaying of a thread until there is sufficient memory and work to keep it up
This option does not accurately describe synchronization. Synchronization is not related to memory availability or workload.
Option B) making every thread start and end at the same time
This option does not accurately describe synchronization. Synchronization is not about controlling the starting and ending times of threads.
Option C) make each thread do the same thing
This option does not accurately describe synchronization. Synchronization is about coordinating the access to shared resources, not making threads do the same thing.
Option D) have each thread start at the same time but not necessarily finish together
This option partially describes synchronization, but it is not complete. Synchronization is not only about starting threads at the same time; it also involves coordinating access to shared resources.
Option E) wait until the required resources, that are used by other threads, become available
This option accurately describes synchronization. Synchronization involves waiting for the required resources to become available before accessing them to prevent data inconsistencies.
The correct answer is E) wait until the required resources, that are used by other threads, become available. This option accurately describes the concept of synchronization in the context of concurrent programming.
