Computer Abbreviations and Terminology
The abbreviations that recur in bank exams, grouped and explained rather than just expanded: hardware and storage, data units, software and operating systems, networking, web and data formats, and the standards bodies, with the comparisons examiners like to test.
What you will be able to do
- Expand the common hardware, storage and data-unit abbreviations and say what each names.
- Group the software, operating-system and networking abbreviations and give a one-line meaning for each.
- Recall the web, data-format and standards abbreviations examiners repeat.
- State the standard comparisons: RAM vs ROM, HDD vs SSD, LAN vs WAN, GUI vs CLI, TCP vs UDP, HTTP vs HTTPS.

How to learn these
Bank exams ask a steady trickle of "expand this abbreviation" and "which of these is not an output device" questions. Rote expansion is not enough — you also need the one-line sense, because the wrong options are usually real terms placed in the wrong group.
Learn them in the groups below (hardware, units, software/OS, networking, web/data, standards). For each entry, be able to say the full form and finish the sentence "it is the thing that …".
