100 common full forms of computer terms and their definitions

Full forms or Acronyms are ways to shorten phrases or terms to make them easier to use or remember.

Here’s a quick rundown:

  1. Initialism: Similar to an acronym, but the letters are pronounced individually rather than as a word.

For example, “FBI” stands for “Federal Bureau of Investigation.”

2. Full Form: The complete, expanded version of an abbreviation or acronym.

For example, “NASA” stands for “National Aeronautics and Space Administration.”

3. Abbreviation: A shortened form of a word or phrase.

For example, “Dr.” for “Doctor” or “Ave.” for “Avenue.”

4. Acronym: A type of abbreviation where the initial letters of a phrase form a new word.

For example, “ATM” stands for “Automated Teller Machine.”
