Erlang unit

An Erlang unit is a special way that people who make computers talk to each other measure the amount of work that happens in a computer program. It's like a really small thing, kind of like a robot worker who does a very specific job. When you put a bunch of these robot workers together, they can do lots of different jobs all at once!

But sometimes, it's hard to measure just how much work each of these robot workers is doing. So people who work with computers came up with the idea of an Erlang unit. It's a way to measure how much of these robot workers are being used in a specific amount of time.

Think of it like this: imagine you have a toy box, and you want to know how many toys are inside. You could just count them all one by one, but that would take a long time. So instead, you put them into groups, like all the cars together and all the dolls together. Then you count how many groups there are, and that tells you about how many toys are in there.

An Erlang unit is kind of like the groups of toys. It's a way to count up how many of these robot workers are being used without having to measure them all individually. This is really helpful when you're trying to figure out how fast a computer program is working, or how many resources it's using.

So next time you hear about Erlang units, just think of them as a way to count up lots of little robot workers without having to count them all one by one!
