Computer & Technology Abbreviations

Computer & Technology Abbreviations are used to shorten technical terms for the benefit of saving time; therefore assist in quickly communicating ideas.

Abbreviated words can also help people who are not familiar with certain technical jargon. It provides a means of explaining terms that may be unfamiliar to them.

Computer abbreviations can also serve as an easy reminder for people already familiar with the usual meaning of each term.

The following is a table of computer and technology terms that are usually used in our I.T. community. Hopefully, this list will be useful for any one seeking knowledge. Be sure to check this page from time to time as we will keep updating and adding abbreviations in the future.
