The capital letters of the alphabet are uppercase glyphs. Uppercase letters are normally used at the beginning of sentences and as the first letter of proper names.
The term uppercase is derived from the days of metal type where the lesser used capital letters were kept in the harder to reach upper case while the more frequently used letters were kept nearer at hand, in the lower case (so now you know how lowercase letters got their name).
Uppercase letters are created on the standard keyboard by holding down the SHIFT key while typing a letter or by pressing the CAPS or CAPS LOCK key then typing (to make all letters uppercase). Using all uppercase letters is called typing in ALL CAPS. Another use of all uppercase are small caps.
