Computer Knowledge: 40 Questions, 20 Marks
Computer Knowledge carries the lowest mark value in the GBO paper: 40 questions worth 20 marks, i.e. 0.5 marks each. It is the cheapest section to secure and the most wasteful to over-prepare, so aim for near-perfect accuracy on basics rather than deep technical study.
Core syllabus
- Hardware and memory: input/output devices, RAM versus ROM, cache, units (1 KB = 1024 bytes, 1 GB = 1024 MB).
- Software: operating system functions, file extensions, MS Word, Excel and PowerPoint, and keyboard shortcuts.
- Networking and internet: LAN/WAN, IP address, HTTP/HTTPS, browser basics, email protocols, cloud storage.
- Databases and security: table/record/field, primary key, virus versus worm, phishing, firewall.
- Digital banking: UPI, NEFT, RTGS, IMPS, mobile banking and ATM terminology - the part most likely to overlap with your job.
Worked example
Cell C2 holds =$A$1+B2. The formula is copied to D3. What does D3 hold? The $ signs lock column and row, so $A$1 stays fixed; B2 is relative and shifts one column right and one row down to C3. Result: =$A$1+C3. Reason: dollar-locked references never move; unlocked references move by the same offset as the copy.
Traps that cost marks
Mixing up NEFT (no minimum, batch-settled) with RTGS (minimum Rs 2 lakh, real-time); calling RAM non-volatile; confusing Ctrl+M (new slide in PowerPoint) with other shortcuts; treating 1 GB as 1000 MB; and, given the low per-question value, spending disproportionate time on any single question.
