Unix/Linux threading model

In Unix/Linux, the threading model allows a single program to perform multiple tasks simultaneously within one process. Threads are like individual workers sharing the same workspace (memory), enabling efficient communication and resource sharing. This model uses lightweight units called threads to run different parts of a program concurrently, improving performance and responsiveness. The system manages these threads, scheduling them to run on available CPU cores, making multitasking efficient without launching separate full programs. Overall, it provides a flexible way to handle complex, multi-tasking applications efficiently within a single program environment.
