Bit of a different post from me today, I wanted to talk about 50 IT acronyms and what they mean as I’ve found most people don’t know these. Or you might know them intuitively, but not have an understanding of them.

Before we start, you can check this out on my website!

Introduction

Not much of an introduction is needed really. I’ll be listing 50 common acronyms within the world of digital technology. Most you’ll have heard of before, but you might not have an understanding of them. Others, you won’t have heard of.

50 IT Acronyms And What They Mean

I’ll be going through them in alphabetical order. Lets jump straight in!

3G/4G/5G

Have you ever wondered what 3G, 4G or 5G is? You’re not the only one! These are all distinct generations of mobile com standards. As you’d expect, 5G is newer than 4G and 4G is newer than 3G.

3G was initially released in the early 2000’s. 4G rolled out in the late 2000’s, early 2010’s and offered a much safer service over 3G. Finally, 5G is the latest version of the standard and is still being adopted in a bunch of locations.
