Description: Process management involves managing the lifecycle and resources of a process. A process is an instance of a running program, which includes the program’s code, its data, and its execution state. Process management is carried out in two main modes: kernel mode and user mode. In kernel mode, the operating system has full access to all machine resources, allowing it to perform critical operations and manage hardware directly. On the other hand, user mode is a more restricted environment where applications operate under limitations to protect the integrity of the system. This separation is crucial for the stability and security of computing systems, as it prevents a malicious or faulty process from affecting other processes or the system as a whole. Process management also includes the creation, scheduling, synchronization, and termination of processes, ensuring that resources are used efficiently and that processes run according to established priorities. Proper process management is essential for system performance and user experience, as it influences how quickly applications run and the system’s ability to handle multiple tasks simultaneously.
