Important Computer Related Abbreviations – You Should Know

Computer Full Form: When it comes to computer science and Information Technology, abbreviations play a huge role. There are tons of jargon in the field and most of them are abbreviated for ease of use. Afterall technology is all about bringing ease hence most technical terms are short forms sticking to the nature of the field. Let’s take personal computer for example, these two words in itself are a simple combination but it has been abbreviated to PC to make it simpler. Things get more complicated than PC as we delve deeper into the IT world.

Almost all of the technical items and devices we use are an abbreviation of some words, most of which we are aware of and most of which we think of as just another word. Though it may not be of that much relevance in a layman’s life/ day-to-day life unless you are working in the field. Computer abbreviations are really important for students, of all ages and standards.
