Computer Knowledge and Typing Proficiency
What this section tests
This section combines computer awareness with a qualifying typing test. Awareness covers hardware and memory units, input/output devices, Windows basics, MS Word and Excel, internet and email, and cyber safety. Typing is tested on a computer with a fixed time limit at a prescribed speed (commonly 25 wpm Hindi or 30 wpm English for ministerial posts - always confirm the figure printed in your official notification).
Core rules
- Memory order: bit → byte → KB → MB → GB → TB; 1 byte = 8 bits, 1 KB = 1024 bytes.
- Shortcuts worth memorising: Ctrl+C copy, Ctrl+V paste, Ctrl+X cut, Ctrl+Z undo, Ctrl+S save, Ctrl+P print, Ctrl+F find, Alt+Tab switch windows.
- Excel: every formula starts with "="; SUM, AVERAGE, MAX and MIN cover most questions.
- Typing: keep fingers on the home row (ASDF / JKL;), do not look at the keyboard, and let accuracy come before speed.
- Net speed = (total words typed − errors) ÷ time in minutes. Gross speed ignores errors, so errors cost you twice.
Worked example
A candidate types 250 words in 5 minutes with 10 uncorrected errors.
Gross speed = 250 ÷ 5 = 50 wpm. Net speed = (250 − 10) ÷ 5 = 240 ÷ 5 = 48 wpm. If the qualifying cut-off is 30 wpm, the candidate qualifies comfortably - but if errors had been 120, the net figure would fall to 26 wpm and fail. This is why a slow, clean typist often beats a fast, sloppy one.
Traps that cost marks
- Typing in the wrong font or layout; Hindi typing in Kruti Dev and Unicode (Mangal) are not interchangeable.
- Rushing and leaving uncorrected errors; each error is deducted from the word count.
- Confusing RAM (volatile) with ROM (non-volatile).
- Not practising punctuation, capitals and numerals, which appear in the actual passage.
- Skipping mock tests on the same software used in the exam.
