b.2.2 system & utility software
Keep your PC healthy and fast. Discover the essential utility tools that clean up your disk, compress huge files, back up your data, and encrypt your secrets.
You wouldn't drive a car for years without ever checking the oil or pumping the tyres, right? Utility Software is the mechanic for your computer. These are the special tools designed to analyse, configure, and optimise your system so it doesn't slow down or crash. We look at Defragmentation to tidy up your hard drive, Compression to shrink massive files so they’re easier to email, and Encryption to scramble your data so hackers can’t read it. We also cover Backups, because losing your homework the night before it's due is a nightmare you definitely want to avoid.
🧐 Sorry, I looked and there is nothing to see.
System and utility software form the critical toolkit required to maintain, optimise, and secure a computer system. This progression maps the pedagogical journey from a foundational awareness of digital housekeeping and basic file copying in the early key stages, through to the advanced application of encryption, disk imaging, and automated scripting at Key Stage 5 and beyond. By explicitly linking theoretical concepts - such as defragmentation and backup strategies - to hands-on procedural tasks, students develop the practical administrative skills necessary to manage real-world IT infrastructure efficiently and securely.
