Threads And Concurrency Questions Medium
A critical section in thread synchronization refers to a specific portion of code that should only be accessed by one thread at a time. It is a mechanism used to ensure that concurrent threads do not interfere with each other while accessing shared resources or variables. By enclosing the critical section within a synchronization construct, such as a lock or a semaphore, only one thread can execute the code block at any given time, preventing race conditions and maintaining data integrity. The critical section is typically used to protect shared resources from simultaneous access, ensuring that only one thread can modify or read the shared data at a time.
