Banking and Computer Awareness
Banking and Computer Awareness
This domain blends banking terminology and operations with basic computer literacy. Expect non-performing asset classification, deposit and account types, negotiable instruments, payment and settlement systems, KYC and anti-money-laundering basics, Basel norms, alongside hardware and software, memory units, keyboard shortcuts, networking, internet terms and cyber hygiene.
Core rules
- NPA: a loan becomes non-performing when interest or principal is overdue for more than 90 days. It is then graded substandard, doubtful and loss.
- Payment rails: RTGS settles in real time and has a minimum of ₹2 lakh; NEFT moves smaller amounts and is not real-time; IMPS runs round the clock through NPCI; UPI is instant and mobile-first.
- Reserve ratios: CRR is the cash share kept with the RBI, SLR is the liquid share held by the bank itself.
- Memory units follow powers of 1024: 1 byte = 8 bits, 1 KB = 1024 bytes, 1 MB = 1024 KB, 1 GB = 1024 MB.
- RAM is volatile, ROM retains content without power.
Worked example
"Convert 2 GB into MB."
Since 1 GB = 1024 MB, 2 GB = 2 × 1024 = 2048 MB. If the question asks for bytes, continue one level: 2048 × 1024 × 1024 bytes. Using 1000 instead of 1024 produces an option that is always present as a distractor.
Traps that cost marks
- Describing NEFT as real-time settlement, or RTGS as having no minimum.
- Swapping CRR and SLR, or claiming RAM keeps data permanently.
- Using decimal 1000 in memory conversions.
- Confusing a savings account with a current account on interest eligibility.
- Mixing up KYC and AML purposes in compliance questions.
