ALSO, is the I/O card inside the power supply, if not where is it?

OS stands for Operating System, such as Windows XP Home,WinXP Pro, MAC OS X, LInux 7.0,etc. Computers use a 'machine language',a binary language, and the OS's are a program that 'speaks' to the computer in 'machine language. The O.S. is stored on your harddrive, put on by the manufacturer of your computer. However you can buy a O.S such as the new Windows Vista, and put it on yourself. BIOS stands for Basic Input/Output System and is a 64MB program that is stored in a BIOS chip on your motherboard. When you turn your computer on the PSU,(Power Supply), gives voltage to a Soft-Power On connection on the'mobo'. This power then goes to the BIOS chip, which reads what kind of peripherals,(cd-drives, floppy's, harddrive), and sends the info to the O.S. This is a rather simplistic answer, and you should surf the net for a more detailed explanation

OS is sold separately.
But if you go for a branded computer, several companies provide OS pre-loaded on your machine.
But FYI, OS is separate entity and Hard Drive is different.
I/O is not integrated with power supply. It is mainly for Input and Output system which is mostly available integrated with Mother board. But earlier it used to come as a separate add-on card.

All hard drives are sold empty and unformatted. The retail OS is sold separately. The OEM OS usually comes bundled with a new PC. If you try to install it in another PC it usually expires and locks in 30 days.

For most "store bought" computers, the OS is installed, with no disks except the back up drive for a total restore.
You can build a system, part by part, but given today's purchasing power in bulk, it doesn't make much sense to build your own unless you buy below value.

Is installed onto the hard drive but doesnt come on the hard drive.
When you buy a computer at like best buy or so they pre install all of your components so its installed for you on your hard drive. If you custom make one like im doing you must install it yourself. So there 2 seperate components.
Hope this helps.
