Does this section need deep knowledge?

It does not. The questions stay practical and the reading is bounded, so limited study gives good results.

Where do I read the banking technology part?

It is not in a general ICT text. Read news and explanatory pieces on banking technology and build your own notes.

Can I skip number systems?

You should not — questions from it are near certain and a little practice brings it fully under control.

The Computer Section of Bank Exams

The computer section is small in bank exams but its marks are the most dependable. The questions do not demand deep technical knowledge and the reading is bounded — which makes the return on time here the highest available.

The areas to hold

Area	What to know
Fundamentals	Hardware, software, input and output
Number systems	Binary and hexadecimal conversion
Networking	LAN and WAN, topologies, protocols
Security	Viruses, phishing, encryption
Banking technology	Online transactions and card systems

The banking technology part is different

Beyond generic computer questions, bank exams include some directly about banking technology — how an online transaction works, the basics of card systems, the security of digital payments. That part is not in a general ICT text, so it has to be assembled from news and explanatory writing about banking technology.

Build the terminology list

A large share of questions here asks for the expansion and function of acronyms. Keep one page with the full form and a one-line explanation beside each, marking the banking-related ones separately — before the exam that single page is enough.

Practise the number systems

The one place here where reading is not enough is number-system conversion. Decimal to binary and binary to hexadecimal — working each conversion ten times yourself saves time in the hall and brings the error rate close to zero.
