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.
The following table represents the standard characters and their decimal values in ASCII.
