ELI5: Computer illiterate here. Why is my computer so loud when it's loading?

Not very tech savvy. My MacBook will make all kind of weird noises when it's loading multiple things, but my iPad won't make a peep. I understand my computer has a fan but is that the only thing making noise? 

Didn't get much help on google.

Your laptop has a mechanical hard drive that swings a metal arm around to access different parts of a spinning disk. Both of those things result in vibration and sound. Your iPad stores data in solid-state memory where accessing requires no moving parts, and so no vibration or sound is produced.
