The letter D is the fourth letter of the Latin alphabet.

1 History

The Semitic letter Dālet probably developed from the logogram for a fish or a door. In Semitic, Ancient Greek (Modern Greek /š/) and Latin the letter was pronounced /d/, in the Etruscan alphabet the letter was superfluous but still maintained (see letter B). Greek letter: Δ (capital) or δ (small) (Delta).

In Cantonese, the sound /d/ means a little bit, from the ancient use of the character 的 (in the phrase "兀的") in Chinese written language. Since 的 is no longer used in this way, Hong Kong residents invented a new character 啲 (which is not supported in many Chinese systems), or simply write D instead.

It is most commonly used b code for capital D is 68 and for lowercase d is 100; or in binaryThe binary or base-two numeral system is a system for representing numbers in which a radix of two is used; that is, each digit in a binary numeral may have either of two different values. Typically, the symbols 0 and 1 are used to represent binary number 01000100 and 01100100, correspondingly.

The EBCDICEBCDIC (Fully, "Extended Binary Coded Decimal Interchange Code") is an 8- bit character encoding used on IBM mainframes and AS/400s. It is descended from punched cards and the corresponding six bit binary-coded decimal code that most of IBM's computer per code for capital D is 196 and for lowercase d is 132.

The numeric character referenceA numeric character reference (NCR) is a common markup construct used in SGML and other SGML-based markup languages such as HTML and XML, and is also a source of much confusion among web document authors.
