15 Information Technology Vocabulary Words Every English Student Should Know

They say we live in “The Information Age.”

All this information moves around thanks to information technology (IT)—using computers and other technology to manage information.

IT is everywhere, including in our hands, offices and homes. Because we use it so often in business and daily life, it’s not only useful but necessary, to know the language of IT.

IT is a specialized field that has a language of its own, so the English words on this list have many meanings. In this post, I’ll only be explaining them in the IT context.

So, here are 15 information technology vocabulary words you can use in daily life and business communication!


1. Monitor

The noun monitor refers to the video screen used to display information on your computer.

5. Boot

The verb to boot has a special meaning in IT. It’s often used in the phrasal verb to boot up, which means to turn on a computer and have it ready for use. You could also say “start up” or “power up.”

There seems to be a problem with my laptop. It wouldn’t boot up this morning.

Boot up is a separable phrasal verb that you can use with a pronoun. You can use “start up” and “power up” in the same way. This means that you can take the preposition “up” and use it later in the sentence. It does not have to follow directly after “boot.”

The opposite of “log in” is “log out,” which is what you should do to exit a site or application.

Sometimes the terms sign in and sign out are also used.
