Difference between Hard Disk and Compact Disk

Hard Disk

hard disk drive (sometimes abbreviated as a hard driveHD, or HDD) is a non-volatile data storage device. It is usually installed internally in a computer, attached directly to the disk controller of the computer’s motherboard. It contains one or more platters, housed inside of an air-sealed casing. Data is written to the platters using a magnetic head, which moves rapidly over them as they spin.
