Definition: It's a term for the "critical section" in software systems, describing part of code that holds all data until the entire program has executed. Definition: The critical section (also known as the Synchronization Region or SR) is a sub-section of a memory block that is essential to the execution of an application. It allows a single thread to access and modify a part of the data within the memory segment, ensuring that any interruption in the execution of this portion will not affect other parts of the program. This section is critical because it handles resource contention - when another thread accesses or modifies the same part of the memory, they need to be synchronized. If there's an interruption, such as a system error or hardware failure, it prevents data corruption and ensures that the application continues running smoothly without any disruption.
