What happens when working set exceeds available RAM?

When your working set gets bigger than the RAM, it’s like having too many toys on the floor when you only have one table to play on.

Imagine you're playing with blocks, and each block represents a part of the computer that needs attention. The table is your RAM, it holds all the blocks you’re actively using right now. But if you bring in more blocks than can fit on the table, some have to be moved to the floor.

That’s what happens when the working set, all the things your computer is trying to use at once, becomes bigger than the RAM. The extra parts are sent to a different place, like the floor or maybe even a closet (that's like the hard drive). This makes the computer slower because it has to keep moving blocks back and forth between the table and the floor.

It’s like when you’re playing with all your toys at once, it gets messy, and it takes more time to find what you need. The computer works harder to keep everything going smoothly!
