I've been studying about computers for pleasure for a week now. I'm on chapter 3. I've learned that the basic in out system happens at the initial booting if a computer and that it's a hard drive systems check. I finally understand what BIOS is. Amirite you computer geeks out there? Anything else I should understand on a basic level?
It's does a little more. I have dabbled with PC's since the early days, build my own. Here is a little more detailed explanation from Lifewire [lifewire.com]
Thanks!
