Description: Thread execution refers to the execution of a thread by the CPU. A thread is the smallest unit of processing that can be managed independently by an operating system. In the context of thread execution, two modes are distinguished: kernel mode and user mode. In kernel mode, the operating system has full control over the hardware and can execute threads with elevated privileges, allowing access to critical resources and performing sensitive operations. On the other hand, in user mode, threads operate under restrictions, limiting their ability to interact directly with the hardware, thus providing a layer of security and stability to the system. Thread execution enables multitasking, where multiple threads can run simultaneously, enhancing the efficiency and performance of applications. Furthermore, thread management is crucial for modern software development, as it allows applications to perform multiple tasks concurrently, optimizing resource usage and improving user experience.
