Computer Knowledge and Office Applications
What this domain tests
Computer fundamentals, memory units, operating-system basics, word processing, spreadsheets, presentations, internet and email, cyber safety, and office tasks such as PDF handling, scanning and e-filing that a court office performs daily.
Core rules
- Memory: 1 KB = 1024 bytes, 1 MB = 1024 KB, 1 GB = 1024 MB, 1 TB = 1024 GB.
- Word: Ctrl+S save, Ctrl+P print, Track Changes records edits, Mail Merge produces bulk letters and labels.
- Excel: A1 is a relative reference, $A$1 absolute, A$1 mixed. Functions: =SUM(A1:A10), =AVERAGE(B2:B9), =IF(C2>=40,"Pass","Fail"), =VLOOKUP(). Text arguments go inside double quotes.
- Email: Cc is visible to all recipients, Bcc hides them; Reply All includes Cc recipients.
Worked example
The formula in C2 is =B2*$F$1 and is copied down to C3. Because B2 is relative it becomes B3, while $F$1 is anchored by dollar signs and stays $F$1. The copied formula reads =B3*$F$1, which is exactly what a percentage or tax-rate column needs.
Traps that cost marks
- Cc versus Bcc, and Reply versus Reply All.
- Ctrl+X cuts while Ctrl+C copies; deleting with Shift+Delete bypasses the Recycle Bin.
- Confusing a formula with its displayed result when tracing errors like #DIV/0! or #VALUE!.
- Forgetting that Excel text inside a formula needs quotation marks.
- Phishing and ransomware questions hinge on recognising suspicious links and unsolicited attachments, not on technical jargon.
