IT Applications
What this domain tests
This domain asks you to match IT tools to real needs in government, business, education, health and daily life, and to judge their benefits and limitations.
Core rules
- E-governance uses IT to deliver public services: online certificates, land records, subsidies, grievance portals and digital lockers.
- E-commerce supports online buying/selling, catalogues, carts, payment gateways and delivery tracking.
- Digital payments include UPI, cards and net banking; always verify the payee and amount before confirming.
- Education uses LMS platforms, e-books, online classes and digital libraries; health uses telemedicine, e-prescriptions and health records.
- Business uses spreadsheets for accounts, databases for records, email for communication and cloud storage for backup.
- Benefits: speed, reach, accuracy, transparency, lower paperwork. Limitations: internet dependence, digital divide, privacy risk, setup cost.
Worked example
A small stationery shop wants to track stock, send bills and accept payments. Use a spreadsheet with columns Item, Opening stock, Received, Sold and Balance, where Balance is a formula. Use email or messaging for order confirmations. Use a UPI QR code for payment and check the transaction status before handing over goods. Keep a weekly backup. The reasoning: each tool matches a distinct task - calculation, communication, payment and data protection.
Traps
- Do not confuse e-governance (public services) with e-commerce (buying and selling).
- A digital payment screenshot is not proof of settlement; verify in the bank/app.
- Cloud storage is not the same as a local backup if the account is lost.
- Not every IT application needs the internet; a local spreadsheet works offline.
- Collecting unnecessary personal data creates privacy and legal risk.
