Fencing (computing)

Fencing in computing is like a safety fence around a construction site. Just like how the fence is put up to keep people out of the construction area so that they don't get hurt, fencing in computing is a way to make sure that nobody messes with the data or information that is being used.

In a computer system, there are many different parts that work together to make everything run smoothly. Sometimes, one of these parts might stop working properly, which can cause problems for the whole system. When this happens, the system needs to make sure that nothing else tries to use that broken part, because it could cause even more problems.

This is where fencing comes in. Fencing is a way for the computer system to separate the broken part from the rest of the system so that nobody can use it. This way, the system can keep running smoothly while the broken part is being fixed.

Think of it like this: imagine you have a toy box with lots of different toys inside. If one of the toys is broken, you don't want to keep playing with it because it might make the other toys stop working too. So you take the broken toy out of the box and put it somewhere else so that nobody can play with it until it's fixed.

That's basically what fencing in computing does - it takes the broken part out of the system so that nobody can use it until it's fixed. This way, the rest of the system can keep working properly without any problems.
