Snoopy cache

Okay kiddo, have you ever played hide and seek with your friends? Well, computers also play a similar game called caching.

Basically, caching means storing things that the computer might need again later on. Just like when you hide your treasure somewhere in your room so that you can find it easily later on.

Now, let's talk about snoopy cache. This type of caching is done by a group of computers that work together in a network. They want to make sure that they all have the same information and are not using their own outdated version of the data.

Just like in hide and seek, everyone needs to know where the treasure is. So, imagine you have a group of friends that want to play hide and seek with you. You decided to hide a treasure in one of your rooms, but you didn't tell everyone where it is. Your friends will keep asking you where the treasure is, and you will keep telling them where it is until everyone knows.

In the same way, the computers in a network that use snoopy cache keep telling each other which data they have, and if they need any new information. This way, everyone knows where the latest data is, and they can all work together efficiently.

So, snoopy cache is like playing hide and seek with your friends, but instead of a treasure, you hide information on a computer network, and everyone wants to know where it is so they can work together better.
