Some of the keys have a special use. There are referred to as command keys. The 3 most common are the Control or(66), Alternate or(67)and the Shift keys though there can be more(the Windows key for example or the Command key). Each key on a standard keyboard has one or two characters. Press the key to get the lower character and hold Shift to get the upper. Disk Drives - All(68)need a drive to get information off - or(69)- and put information on the disk - or(70). Each drive is designed for a specific type of disk whether it is a CD, DVD, hard disk or floppy.
