ELI5: Explain Like I'm 5

High memory area

Imagine you have a big toy box filled with all of your toys. Now, imagine there are a few special toys that you really like to play with all the time, like your favorite action figure or LEGO set. You might want to keep these special toys in a special place where they are easy to reach and play with.

Now, imagine your computer is like your toy box and all of the programs and data on your computer are like your toys. Just like you have special toys you like to play with all the time, your computer has special programs that it uses a lot and needs to access quickly. These special programs are stored in a special place in your computer's memory called the high memory area (HMA).

The HMA is like a special shelf in your computer's memory where important programs and data are kept so they can be accessed quickly when your computer needs them. When your computer is running, it is constantly accessing and using different programs and data. By keeping the most important programs in the HMA, your computer can access them faster and run more efficiently.

So, to sum it up, the high memory area is like a special shelf in your computer's memory where important programs and data are kept so they can be accessed quickly and help your computer run more efficiently, kind of like how you keep your favorite toys in a special place in your toy box so you can play with them easily.
