5 internal hardwares of a computer?

Hard drive- Holds the Operating System, and all files

Floppy drive- for saving/downloading files onto a old style removable disk

motherboard-holds CPU, chipsets, frontside bus for connectivity between devices

power supply-supplies power to all above and to external usb devices

fans-to prevent hard drive, mother board, etc. from overheating.

I hope this is the stuff you were looking for, or if not repost with more info.

It can be a driver for sure. How is the reader attached? USB? Firewire? External slot? Internal slot?

Motherboard, CPU, Memory, Hard drive and power supply. Don't want to explain their functions; it will take a few pages. You can start up a computer with these hardware.
