What are CPU handles and what is their function?

Answer 1

CPU handles, often referred to as process or thread handles, are unique identifiers used by the operating system to manage and track the execution of processes or threads within a CPU. They allow the OS to allocate resources, schedule tasks, and maintain the state of each process or thread efficiently. By using handles, the system can perform operations such as terminating a process, adjusting its priority, or retrieving its status without directly interacting with the underlying memory or process data structures. This abstraction simplifies resource management and enhances system stability.
