Why do computers slow down, but then you restart them and they work again?

Could you explain in the form of an analogy? Also, has this improved over time? Does it have anything to do with registry and defrag? Is it different for Mac vs PC? Thank you 🙂

There are several reasons, but one of the most-common reasons is that everything you do on your computer takes up some of the limited memory in the computer (specifically the RAM, or Random Access Memory, which is different than space on a disk). As you do things on the computer, such as browse Reddit, your computer keeps taking up more memory with every post you click, every photo you view, every link you click. When that memory becomes more limited, your computer operates more slowly, as it struggles to try to “find a place to fit more stuff.” However, once you restart your computer, most of that memory is wiped clean and you start fresh, so your computer is often faster. Basically, on a restart, your computer “empties the trash can,” so you can start filling it up again, without constantly having to try to compact the trash to fit more in the can.
