Which software is responsible for coordinating program execution and resource management in a computer system?

• A. Operating System
• B. Memory Manager
• C. Register
• D. Data Bus

Answer: (A)

The operating system is the software that coordinates how programs run and how resources are shared on a computer. It schedules which process gets the CPU, manages memory so programs don’t interfere with each other, and handles input/output and access to devices. This coordination across CPU time, memory, and I/O is what lets multiple programs run smoothly at once and keeps the system stable. A memory manager sounds like the right kind of tool, but it focuses specifically on allocating and freeing memory rather than coordinating all program execution and resource sharing. The other options are hardware: a register sits inside the CPU to hold data being processed, and the data bus is the physical pathway that moves data around. They don’t manage or coordinate software at all.
