If you ask for help with an unknown problem in any online forum, the first responses you get will probably be along the lines of, “What’s under your hood?” If you are selling or buying a used computer, it’s important to have a list of what’s inside of it. If you want to buy a memory upgrade, you’ll need to know what sort of RAM memory is already in your PC to get the compatible kind. If you need to call tech support, you may be stuck when a rep asks for the make and model of your video card, or the type of RAM that’s installed on your PC. Why would you want to know what's inside that plastic and metal box you call a computer? I can think of several good reasons.
