ASCII Values Alphabets ( A-Z, a-z & Special Character Table )
ASCII (American Standard Code for Information Interchange) is a standard character encoding used in telecommunication. The ASCII pronounced ‘ask-ee’, is strictly a seven-bit code based on the English alphabet. ASCII codes are used to represent alphanumeric data.
The code was first published as a standard in 1967. it was subsequently updated and published as ANSI X3.4-1968, then as ANSI X3.4-1977, and finally as ANSI X3.4-1986. Since it is a seven-bit code, it can at the most represent 128 characters. it currently defines 95 printable characters including 26 upper case letters (A to Z), 26 lower case letters, 10 numerals (0 to 9), and 33 special characters including mathematical symbols, punctuation marks, and space characters. They represent text in, telecommunications equipment, and devices. These include numbers, upper and lowercase English letters, functions, punctuation symbols, and some other symbols.
In total, there are 256 ASCII characters, and can be broadly divided into three categories:
- ASCII control characters (0-31 and 127)
- ASCII printable characters (32-126) (most commonly referred to)
- Extended ASCII characters (128-255)
