Coming from a technical background I'm slightly confused. What is the difference between simultaneously and concurrently? How do we use these words?

This question is too basic; it can be definitively and permanently answered by a single link to a standard internet reference source designed specifically to find that type of information. If this question can be reworded to fit the rules in the help center, please edit the question.
I just looked these up in an online dictionary; this is what I found:
Both of them mean "at the same time," and are almost interchangeable.
That said, if I had to point out a slight difference, I'd say that concurrently occurs over a longer time, and is a bit less synchronized than simultaneously.
In that example, I wouldn't swap the two words in question.
In addition, concurrent has a few additional meanings, most of which amount to "in agreement," as in "two people working concurrently." That is to say, they're working towards the same goal. The other meaning of concurrent is related to geometry, where you might say two lines were concurrent: they're going to intersect at a common point.
