"Discuss the relationship between the Operating System and Utility Software, explaining why utilities are generally considered separate from the OS core." (4 marks)
Core vs Additional: The OS provides the fundamental platform required for hardware to function; without it, the PC is useless. Utility software provides additional housekeeping tasks to maintain and optimise the system.
Bundling: While most modern Operating Systems come bundled with basic utility programs (like a built-in defragmenter), they are not strictly part of the essential core OS architecture.
Third-party options: Because they are separate, users can install superior third-party utility software (like specialized encryption tools) to replace the bundled default utilities.
