Ram is temporary memory that is not stored long term. Each time you turn the computer off, it is “forgotten”. Let’s say you have to copy a very long sequence of more than 500 digits from one page of a book to another one. You can memorize maybe 10 digits, turn the pages, write them and resume to the first page starting with the following 10 digits. It makes no sense to try to memorize the whole sequence before turning the pages and writing everything in one go. In this situation, RAM would be the number of digits you are able to quickly memorize before turning the pages and writing them down. Then you forget this first small sequence of digits and proceed to the next. The more digits you memorize in one go, the faster you can copy and paste the whole 500 digit sequence from one page to the other.
