In an operating system, processes and threads are fundamental concepts that manage the execution of programs. Both processes and threads represent units of execution, but they differ in terms of their structure, execution, and resource requirements.

A process is an independent program in execution. It is a heavier unit of execution that includes its own memory space, system resources, and execution context. Each process has its own address space, meaning the memory used by one process is not directly accessible by another process. Communication between processes often requires inter-process communication (IPC) mechanisms, such as pipes, sockets, or shared memory. Processes are typically isolated from each other to prevent interference, ensuring ____ __________ ________ ____ ____ ______ _____.
