Important Abbreviations Questions and Answers

Answer: A

EBCDIC stands for Extended Binary Coded Decimal Interchange Code.

EBCDIC is an 8-bit character code developed by IBM for its mainframe computers. It extended the earlier 6-bit Binary Coded Decimal (BCD) code, which is where 'Binary Coded Decimal' in its name comes from. ASCII, used by most other computers, is the American Standard Code for Information Interchange.

The other expansions replace 'Binary Coded' with 'Bit Code' or 'Bit Case', which are not part of the name.

Answer: C

USB stands for Universal Serial Bus.

USB is the standard interface for connecting devices such as keyboards, mice, printers and storage drives to a computer, and for charging. Data travels one bit after another (serially) along the bus, and the standard is universal in the sense that one type of port serves many kinds of device. The storage device the question means is the USB flash drive.

'Unlimited', 'Band' and 'Service' are not part of the name, which rules out the other three options.

Answer: C

GPU stands for Graphical Processing Unit.

The GPU, usually written as Graphics Processing Unit, is a processor designed to render images and video. It has thousands of small cores that work in parallel, which also makes it useful for scientific computing and for training artificial intelligence models.

'Ground Processing Unit' and 'General Processing Unit' are not expansions of GPU, which leaves the graphical option.

Answer: D

OMR stands for Optical Mark Recognition.

An OMR scanner detects the presence of marks, such as filled bubbles, on a printed sheet by shining light and measuring what is reflected. That is why answers must be marked with a dark ball-point pen in the right circle.

The other expansions are wrong: the technology reads marks optically, not magnetically, and it recognises marks rather than recording responses.

Answer: C

The key's answer is Automated Teller Machine.

An ATM is a machine that lets bank customers withdraw cash, check balances and make other transactions without a human teller. 'Automated teller machine' is the standard expansion used by banks and the Reserve Bank of India.

'Automatic teller machine' is a looser variant that also appears in print, but the key takes the standard form. 'All Time Money' and 'Any Time Money' are popular backronyms, not what the letters stand for.
