Prosessimuisti, also known as process memory, refers to the memory space allocated to a running program or process by the operating system. This memory is essential for the execution of any software, as it holds the program's instructions, data, and other necessary information. When a program is launched, the operating system allocates a dedicated portion of the main memory (RAM) for it. This allocated space is then used to store various components of the process.

The contents of process memory can be broadly categorized into several segments. The code segment, or text segment, contains the executable instructions of the program. The data segment stores global and static variables. The heap is a region of memory that is dynamically allocated during the program's execution, typically for objects or data structures whose size is not known at compile time. The stack is used for managing function calls, local variables, and return addresses. Each process operates within its own isolated memory space, meaning one process cannot directly access the memory of another process. This isolation is a crucial security and stability feature of modern operating systems, preventing one faulty program from corrupting the data or crashing other running applications. The management and allocation of process memory are handled by the operating system's memory manager.
