Okay kiddo, so you know how your computer has a little chip inside it called the CPU, right? Well, that chip is very important because it controls all the other parts of the computer and helps it run properly.
But sometimes, there can be things called electromagnetic waves that can mess with the CPU and make it not work right. Kind of like how a really loud noise can make it hard for you to hear someone talking to you.
That's where CPU shielding comes in. It's like a special suit of armor for the CPU that blocks those electromagnetic waves and keeps the chip safe. Think of it like a shield that a knight wears to keep them safe in battle.
So, when computer makers design a computer, they make sure to put in something called a shield around the CPU. It's usually made of metal and covers the chip like a little dome. This way, the electromagnetic waves can't get in and hurt the CPU.
Overall, CPU shielding is just a way to protect that important little chip inside your computer and make sure it can do its job properly.
