Core system software: What is the name of the system that deals with running the actual computer (resource management, scheduling, I/O) rather than solving programming problems directly?

Introduction / Context:An operating system (OS) abstracts hardware and manages resources so applications can run safely and efficiently. It is distinct from application programs or source/object code artifacts produced by compilers.

Given Data / Assumptions:

• We focus on software that manages CPU, memory, devices, and files.
• It provides services (system calls), security, and scheduling.
• It is not a particular application solving a business or algorithmic problem.

Concept / Approach:

The OS coordinates the computer’s operation, offering a platform for application programs. It runs privileged code, handles interrupts, and enforces isolation. Hence, among listed terms, “Operating system” best names the system that runs the computer.

Step-by-Step Solution:

Verification / Alternative check:

Standard computing definitions place process management, memory management, file systems, and device drivers under the OS umbrella.

Why Other Options Are Wrong:

• Systems program: generic term; could be compilers or linkers.
• Object program and Source program: program code artifacts, not the manager.

Common Pitfalls:

Equating “systems programming” tools with the OS itself; forgetting that OS includes kernel plus essential services.

Final Answer:

Operating system
