IT Glossary

IT GlossaryAt Integratech we know that IT terminology can be confusing to understand so we have created this glossary. The rate at which information technology changes means that new acronyms are being created at a rapid rate and it can be hard to keep up-to-date with these terms.

On this page you will find an alphabetic glossary of some of the most commonly used IT terms. We will be adding to this section on a regular basis, so be sure to check back for more helpful IT jargon explained in an easy-to-understand way.
