Sünkroonsustrateegiad, also known as synchronization strategies, refer to methods used to coordinate the activities of multiple processes or threads in a computing system. The primary goal of these strategies is to ensure that shared resources are accessed in a controlled manner, preventing data corruption and maintaining the integrity of the system. This is particularly important in concurrent or parallel programming environments where multiple execution paths can potentially interact with the same data simultaneously.

One common synchronization strategy is the use of locks. A lock, or mutex, is a mechanism that grants exclusive access to a resource. When a process or thread wishes to access a shared resource, it first attempts to acquire the lock. If the lock is available, the process acquires it and proceeds to use the resource. If the lock is already held by another process, the requesting process must wait until the lock is released. Once the process has finished with the resource, it releases the lock, allowing other waiting processes to acquire it.

Another important strategy involves semaphores. A semaphore is a signaling mechanism that controls access to a common resource by maintaining a counter. When a process wants to access the resource, it decrements the semaphore. If the semaphore's value becomes negative, the process is blocked. When a process finishes with the resource, it increments the semaphore, potentially unblocking a waiting process. Condition variables are also used to manage synchronization, allowing threads to wait for a specific condition to be met before proceeding. These strategies are fundamental to building reliable and efficient concurrent software.
