ASCII may refer to any of the following:

Short for American Standard Code for Information Interexchange, ASCII is a standard that assigns letters, numbers, and other characters in the 256 slots available in the 8-bit code. The ASCII decimal (Dec) number is created from binary, which is the language of all computers. As shown in the table below, the lowercase "h" character (Char) has a decimal value of 104, which is "01101000" in binary.

ASCII was first developed and published in 1963 by the X3 committee, a part of the ASA (American Standards Association). The ASCII standard was first published as ASA X3.4-1963, with ten revisions of the standard being published between 1967 and 1986.

ASCII sections
The ASCII table is divided into three different sections.

Non-printable, system codes between 0 and 31.
Lower ASCII, between 32 and 127. This table originates from the older, American systems, which worked on 7-bit character tables.
Higher ASCII, between 128 and 255. This portion is programmable; characters are based on the language of your operating system or program you are using. Foreign letters are also placed in this section.
