Here at Trichromic we prefer not to use too many computer-related TLAs (three letter acronyms), FLAs (Four letter Acronyms) and unnecessary IT jargon when communicating with our clients.

However, these can't always be avoided (and some like to use them when they shouldn't) so here you'll find a categorised glossary of the most commonly used terms which could be useful to anyone talking to IT departments or even an outsourced IT provider like Trichromic. We'll keep expanding this list through 2017 and adding descriptions when time permits so please keep visiting to view the latest updates. You can contact us for more information on any of the descriptions below or even for how Trichromic can provide IT support and help improve the efficiency of your business processes by harnessing the latest technology. ~ Lloyd Reid
