When you turn on your computer, the first thing that happens is the boot process. It's kind of like when you wake up in the morning and have to get ready for the day.
When the computer "wakes up," the first thing it needs to do is figure out what it's supposed to do. It does this by checking the BIOS, which is like your computer's brain. It tells the computer what hardware it has (like the screen, keyboard, and mouse), and what it's supposed to do with them.
Next, the computer looks for the operating system (OS), which is like your computer's clothes. It helps it look good and do what it's supposed to do. The OS tells the computer how to start up and how to run programs.
Once the computer has found the OS, it loads it into memory so that it can start running programs. It's like putting on clothes and getting ready to do things for the day.
Finally, the computer is ready to use, and you can start doing things on it like playing games, writing up homework, or watching videos. That's what booting is all about - getting your computer ready to use!
