Just curious about it, but can’t understand why is it like that.

Some things you hold in the back of your brain, like your birthdate and fond memories. Other things you need right now but then forget about right away like if you’re trying to calculate (35*6+4)/2. You do the multiplication in your head but once you’re done multiplying and adding you don’t need to remember any of those terms for the division and you can safely forget about them even if you want to keep the answer. The storage drives in a computer are like your long term memory and the RAM is like your memory for the stuff you need to remember right now but not after you’re done with them. Some things you need to remember right now are complicated and some computer tasks also take a lot more short term memory than others. If a computer runs out of short term memory it can store stuff in the storage drives but it gets very slow when it does this.
