Описание: Fix “slow computer” problems like an examiner. This lesson explains storage optimisation using simple bookshelf analogies so Grade 10–12 CAT learners can clearly distinguish fragmentation, defragmentation, disk cleanup and compression. We look at what fragmentation really is, how defrag reorganises files, how cleanup frees space by deleting junk, and how compression “squeezes” files without deleting them. You’ll also learn a decision flowchart for exam questions such as “A learner’s laptop is slow and almost full – what can they do?” and practise short NSC‑style questions to make the answers automatic.
