Concurrent user

Imagine you have a toy car and your friend has a toy truck. You both want to play with your toys at the same time. If you both play with your toys at the same time, that's like having two concurrent users.

In the same way, a computer program or website can have users who use it at the same time, and that's called concurrent users. So if five people are using a website all at the same time, that website has five concurrent users.

Having a lot of concurrent users can be challenging because the computer program or website needs to work quickly and smoothly for everyone. It's like playing with a lot of toys at the same time - you need to make sure everything is organized and everyone gets a turn so that nobody gets frustrated or upset.
