What is Caching? ELI5

Caching is a way of storing information in a computer so that it can be accessed quickly and efficiently. Caching helps to improve the performance and efficiency of a computer, by storing frequently used data in a special location where it can be accessed quickly and easily.

Imagine you are playing a game of hide and seek with your friends. You are all hiding in different places, and one person is trying to find everyone else. Without caching, it would be difficult for the person who is looking for everyone to remember where each person is hiding, and they would need to search all over again each time they want to find someone. But with caching, the person who is looking for everyone can use a special map or memory to remember where each person is hiding, and they can use the map or memory to find each person quickly and easily.

For example, let's say you are playing hide and seek with three friends, and you are using a map to keep track of where each person is hiding. With caching, you can use the following rules to improve the performance and efficiency of the game:

Store frequently used data: The person who is looking for everyone can store the locations of each person on the map, so that they can easily find each person again without needing to search all over again.

Access data quickly: The person who is looking for everyone can use the map to quickly find the location of each person, without needing to search for it again.

Use data efficiently: The person who is looking for everyone can use the map to find each person quickly and efficiently, without wasting time or energy searching for the same location multiple times.

Overall, caching is a helpful way of storing and accessing information in a computer, just like a map or memory helps you to find and remember the locations of things in a game of hide and seek.
