Synchronization
Synchronization is a fundamental concept in computer science and software development that ensures orderly and coordinated access to shared resources, such as data, files, or hardware, in concurrent or parallel systems. It prevents race conditions, data corruption, and inconsistent states by controlling the execution order of threads, processes, or distributed components. Techniques include locks, semaphores, mutexes, and barriers to manage access and maintain system integrity.
Developers should learn synchronization when building multi-threaded applications, distributed systems, or any software where concurrent access to shared resources occurs, such as in web servers, databases, or real-time processing tools. It is crucial for ensuring data consistency, avoiding deadlocks, and improving performance in parallel computing environments, like those using Java, C++, or Go. Without synchronization, applications may suffer from unpredictable behavior and critical failures.
