Threads
Threads are a fundamental programming concept that enables concurrent execution within a single process, allowing multiple sequences of instructions to run simultaneously. They share the same memory space and resources of the parent process, making them lightweight compared to processes. Threads are used to improve application performance, responsiveness, and resource utilization in multi-core systems.
Developers should learn about threads when building applications that require parallelism, such as handling multiple user requests in web servers, performing background tasks in GUI applications, or processing large datasets efficiently. They are essential for leveraging modern multi-core processors to achieve better throughput and reduce latency in I/O-bound or CPU-intensive operations.
