Basic Computer Skills
What the domain tests
Basic Computer Skills tests practical digital literacy: operating systems, file management, word processing, spreadsheets, email, internet use, and basic security. Questions are usually task-based rather than theoretical.
Core rules and concepts
- Know common extensions: .docx, .xlsx, .pptx, and .pdf; understand Save versus Save As.
- Shortcuts: Ctrl+C copy, Ctrl+X cut, Ctrl+V paste, Ctrl+S save, Ctrl+Z undo, Ctrl+F find.
- Spreadsheet formulas start with =; relative references change when filled, while absolute references use $ to stay fixed.
- Email needs a clear subject, concise body, correct recipients, and checked attachments.
- Security basics: strong unique passwords, backups, screen locking, and verification of suspicious links or requests.
- Networks: LAN versus WAN; a browser is not the same as a search engine.
Worked example. Cell D2 contains =B2*$C$1. When filled down to D3, B2 becomes B3 but $C$1 stays fixed. Reasoning: the dollar signs lock column and row, so every row multiplies by the same rate.
Traps that cost marks
Confusing copy with move; deleting a shortcut instead of the file; clicking unknown attachments; assuming Save As overwrites the original; and using a relative reference where a fixed rate is required.
