Systems Software
The essential software that manages the hardware and provides a stable platform for your applications.
Part 1: The Operating System
Part 2: Utility Housekeeping
2. Defragmentation
Learn why hard drives slow down over time and how reorganising file fragments contiguous blocks drastically improves physical read/write head access times.
Run Defrag Visualiser3. Compression & Encryption
Master algorithms that shrink file sizes to save storage space and accelerate network transfer speeds, alongside vital public data scrambling tools.

"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.
