Which statement is true about a process?

• A. A process is a hardware component.
• B. A process is an executing program developed for the end user.
• C. A process is a system file.
• D. A process is a network packet.

Answer: (B)

A process is the executing instance of a program. When a program is loaded from storage and actually runs, the operating system creates a process to manage it. The process has its own state, program counter, stack, heap, and allocated resources like memory pages and open files, and it’s the unit the CPU schedules and switches between. This distinguishes it from a hardware component (a physical device), a system file (data stored on disk used by the system), or a network packet (data sent over a network). Therefore, describing a process as an executing program developed for the end user best captures the idea that a process is a running instance of a program under the OS’s control.
