Operating speed

Operating speed is how fast something can do its job. Let's pretend that you have a toy car racetrack, and you have two toy cars that can race on it. One of the cars is faster than the other because it can go around the track more times in one minute than the other car can.

In real life, things like cars or computers can have different operating speeds too. For example, a computer with a faster operating speed can do things like load websites or play games quicker than a slower computer.

But, just like the toy cars, a faster operating speed also means that it can use up more energy or make more noise. So when you are choosing something that has an operating speed, you need to decide if you want something really fast, or if you are okay with something that might be a bit slower but doesn't use up as much energy or make as much noise.
