Imagine you are supposed to color a picture, but you accidentally color on the wrong side of the paper. This is similar to wrong-side failure in technology.
Sometimes, when we are making things or writing code for them, we might accidentally put something on the wrong side or in the wrong part of the thing we are making. This can cause problems later on when we try to use our creation.
For example, let's say we are making a car and accidentally put the steering wheel on the wrong side. This can cause the driver to have a hard time controlling the car or even cause accidents. Similarly, in technology, a wrong-side failure can cause our creation to not work properly or even break completely.
To prevent wrong-side failure, we need to carefully plan and double-check our work before we make something. This way, we can catch any mistakes before they become big problems.
