Final answer:
The 'process image' comprises program, data, stack, and attributes defined in the process control block (PCB), which is key to understanding process management in operating systems.
Step-by-step explanation:
The process image is the collection of program, data, stack, and attributes defined in the process control block (PCB).
A process image represents the current state of a process that is managed by the operating system. The process control block contains important information about the process, such as its priority, state, CPU register contents, memory management information, and I/O status information. The program part of the image includes the executable code, the data part includes variables and dynamically allocated memory, the stack part contains the procedure call stack which keeps track of active subroutines and functions within the program, and the attributes may include various flags and states related to process control.
Understanding the role of the process control block and the process image is crucial for those studying operating systems and learning how multitasking and process management are achieved in computer systems.
