Okay kiddo, n11 code is something that helps us understand and organize things in our computer systems. It's like putting all your toys in a box and labeling it "toys".
When we have a lot of information, like a bunch of toys, we need to sort them by type so we can find them easily later. The n11 code is like a label that tells the computer what type of information it is.
For example, let's say we have a lot of pictures on our computer. We can label all the pictures with the n11 code "IMG" to tell the computer that they are all images. Then, if we want to find a specific picture later, we can ask the computer to show us all the files with the n11 code "IMG".
So, the n11 code is like a special tag that helps us organize and find things in our computer system!
