Just think that you go to a huge library and they tell you to search all the books written between 1923 and 1984 that contains the word “advertisement”.
That will take you a lot of time, right?
You will write down in a paper every match and next time someone asks you for that information you wont need to go to the library and you will have the results in seconds.
That’s the cache!!
An a comic explaining it 😉
