What is ASCII?

ASCII - American Standard Code for Information Interexchange - assigns letters, numbers, characters, and symbols a slot in the 256 available slots in the 8-bit code.

Most computers use ASCII to represent text, which makes data transfer between different systems possible.

The standard ASCII text uses 7-bits to represent the characters. Other extended character sets use 8-bits to represent non-English characters.

ASCII Sections

• 0-32 are Non-printable system codes.
• 32-127 are Standard ASCII or lower ASCII codes and are based on 7-bits.
• 128-255 are Higher ASCII codes. These depend upon the language of the Operating System and program.
