ASCII stands for American Standard Code for Information Interchange, which is a character encoding standard
used in electronic communication. An ASCII code is a numeric representation of a character, such as a letter,
number, or punctuation mark, that is used to represent that character in digital communications.
In ASCII, each character is assigned a unique code that consists of a seven-bit binary number (0s and 1s).
This code can then be translated into decimal, hexadecimal, or octal representation for use in programming
and other digital applications. For example, the ASCII code for the letter "A" is 65, the code for the letter
"a" is 97, and the code for the digit "1" is 49.
ASCII is one of the oldest character encoding standards and is still widely used today in many computer
systems and programming languages.
