Information Technology and Computer Skills
Core concepts
Expect questions on computer fundamentals (hardware, software, input-output devices, memory units), operating systems and file management, word processing and spreadsheets, internet and networking basics (IP address, browser, email, URL, LAN/WAN), and cyber safety (password hygiene, phishing, malware, digital signatures). Awareness of e-governance and police IT systems is increasingly relevant.
Traps
Memory-unit questions swap bit and byte, or KB and Mb. Hardware questions confuse RAM with ROM, or storage with memory. Networking questions mix IP address with MAC address, or browser with search engine. Cyber questions often use a plausible but wrong definition: phishing is a deceptive message that steals credentials, not a virus. Spreadsheet questions confuse a formula with a function or relative with absolute reference.
Rule of thumb and worked example
Use unit logic: 1 byte = 8 bits; 1 KB = 1024 bytes; 1 MB = 1024 KB. Example: a 2 MB file is about 2 × 1024 × 1024 bytes, far more than 2 million bits. For security, remember the CIA triad: confidentiality, integrity, availability. A password should be long and unique; reusing one password across sites is the classic wrong option.
Study method
Practise spreadsheet formulas and file operations hands-on; practical familiarity answers definition questions faster than memorisation.
