ASCII Stands for 

ASCII stands for American Standard Code for Information Interchange. It is a standard of character encoding in the field of electronic communication. ASCII codes are text for telecom, computer, and mobile devices. The most modern character-encoding systems are ASCII based, although many other characters are supported.

What is ASCII?

The ASCII code describes text (you can say each character) using different numbers because computers are able to understand numbers only. So a machine understands the numbers and ASCII provides that numbers against each text character.

Originally, ASCII consists of 128 characters from 0 to 127 but is now extended to 256 characters from 0 to 255. It represents all English alphabets as digits. It includes capital letters, small letters, and punctuation marks as well. The English capital letter A is represented by 65 in ASCII, and B is represented by 66 and so on.

For instance, lowercase letter ‘i’ would be denoted in the ASCII format with binary code ‘1101001’‘1101001’ that is equal to hexadecimal ‘69’‘69’ (i being the 9th letter) = decimal 105105.

ASCII-code order is also known as ASCIIbetical order. All uppercase letters precede lowercase letters or to put it rather simply ‘Z’ precedes ‘a’. On the other hand, digits and many punctuation marks precede letters altogether.
