Understanding ASCII

Variation A

Acronym for the American Standard Code for Information Interchange.
Pronounced ask-ee, ASCII is a code for representing English characters
as numbers, with each letter assigned a number from 0 to 127.
For example, the ASCII code for uppercase M is 77. Most computers use
ASCII codes to represent text, which makes it possible to transfer
data from one computer to another

Variation B

A standard code, consisting of 128 7-bit combinations,
for characters stored in a computer or to be transmitted
between computers.

Variation C

A standard for assigning numerical values to the
set of letters in the Roman alphabet and
typographic characters.

Variation D

A code for information exchange between computers
made by different companies; a string of 7 binary
digits represents each character; used in
most microcomputers

Variation E

A code that assigns the numbers 0 through 127
to the letters of the alphabet, the digits
0 through 9, punctuation marks, and certain
other characters. For example, the capital
letter A is coded as 65 (binary 1000001).
By standardizing the values used to represent
written text, ASCII enables computers to
exchange information. Basic, or standard,
ASCII uses seven bits for each character
code, giving it 27, or 128, unique symbols.
Various larger character sets, called
extended ASCII, use eight bits for each
character, yielding 128 additional codes
numbered 128 to 255.

Variation F

(American Standard Code for Information Interchange)
The numerical code used by personal computers.
