Well little one, have you ever heard someone talk about a computer? Of course you have! A computer is a machine that can do lots of things like play games, help you learn, and even talk to your friends. But have you ever heard of an NDR computer before?
NDR stands for "non-destructive read". That might sound like a big, scary phrase, but it's really quite simple. In a regular computer, when you want to read something, like a song or a game or a picture, the computer has to copy that information and save it in a different place in the computer's memory. That's called a "destructive read" because the computer kind of destroys the original information in order to use it.
But with an NDR computer, it's different. When you want to read something on an NDR computer, it doesn't copy and destroy the original information. It just reads it right where it is! That means that the original information stays safe and sound right where it is, and the computer can still use it without harming it.
Isn't that pretty cool? It's like the computer is a very good listener, and it can hear what you're saying without interrupting or changing anything. This can be very useful, especially for things like scientific research or big data analysis, where you want to keep the original information intact so you can study it carefully.
So that's the explanation for NDR computers, little one. They're just like regular computers, but they can read things without destroying the original information. Cool, huh?
