Eli5: What is cached data?
In: Technology
Well, son, every day last year, you told me that you want to see your mommy, daddy, your uncles and aunties, grandpas and grandmas all together at the same time.
This was a hard thing to give you. Grandpa Rick and grandma Betty live far away in Canada. Uncle Donald is under house arrest for repeated public indecency. Auntie Karen is always fighting with her boyfriend Man Ager.
I had to spend a lot of time and effort to get us all together for your birthday yesterday, and so I took this picture that I want you to have. A picture of all of us together and happy.
This picture is like cached data, it preserves the result of a complicated process that you often asked of me. You can now look at it with very little effort and all it takes is a little bit of space on your nightstand.
