Read Explanation:
ASCII
ASCII stands for American Standard Code for Information Interchange.
It's a character encoding standard that uses seven bits to represent 128 different characters, including uppercase and lowercase letters, numbers, and punctuation.
The first 32 characters are control codes, while the remaining 96 are printable characters.
For example, the character 'A' is represented by the decimal value 65.
While the original ASCII is a 7-bit code, it's often stored and transmitted using an 8-bit byte, with the eighth bit either set to 0 or used for a parity bit for error checking. This is why you might sometimes see references to "extended ASCII," which uses all eight bits to represent 256 characters. However, the standard ASCII itself is a 7-bit code.
