Description: Process migration is the transfer of a process from one environment to another, which involves moving its state and execution context. This concept is fundamental in operating systems, where processes can be moved between different execution contexts, which may include physical or virtual machines, or between different cores of a processor in multiprocessor systems. Effective process migration allows for load balancing, resource optimization, and improved overall system performance. Process migration may also include transferring processes between different operating modes, such as kernel mode and user mode. In kernel mode, the operating system has full access to hardware resources, allowing it to perform critical operations and manage memory efficiently. On the other hand, user mode is a more restricted environment where applications have limited access to system resources, helping to protect the stability and security of the operating system. Overall, process migration is a key mechanism that allows flexibility and efficiency in task execution across different computing environments, ensuring that processes are managed appropriately according to their execution context.
