Threading

Threading enables concurrent execution of multiple instruction sequences within a single process to maximize CPU efficiency.

Threading allows a single process to manage multiple execution paths simultaneously while sharing a common memory space. By utilizing multi-core hardware (such as an Intel Core i9 or Apple M3 Max), developers can offload I/O-bound tasks to background threads to keep the main interface responsive. A high-performance web server might maintain a pool of 200 threads to process incoming requests in parallel, significantly cutting down on wait times. Engineers use synchronization primitives (like Mutexes and Semaphores) to ensure data integrity and prevent race conditions during concurrent access.
