ASCII stands for “American Standard Code for Information Interchange” As you may know, computers only work with HIGH(1) and LOW(0) electrical states, known as bits, with correspond to mathematical Base 2 numbers. Numbers are easy to store using bits, as for example, ‘8’ would be ‘1000’ at Base 2. But graphically, you don’t have ‘8’, neither ‘0’ or ‘1’, bits in fact are just states: “On” when powered, “Off” when not, so how could we display characters on a screen? Skipping how they did the screen printing itself, ASCII is a Code that tells to the display what he should print given an input. This Code output is, internally, a byte (8 bits) that are simple regular numbers at Base 2 (as ‘00001000’ stands for 8 at Base 10). So what ASCII in fact is: The mapping of Binary Numbers that correspond to Actions (that may be an action to Display a Graphical Representation of an Character or, for example, Remove Previous Character, as does Backspace - ASCII Code ‘00001000’)

If am wrong then please explain what is ASCII ASCII is a code for representing English characters as numbers, each letter of english alphabets is assigned a number ranging from 0 to 127. For example, the ASCII code for uppercase P is 80. In Java programming, we have two ways to find ASCII value of a character 1) By assigning a character to the int variable 2) By type casting character value as int

ASCII (American Standard Code for Information Interchange) is the most common format for text files in computers and on the Internet. In an ASCII file, each alphabetic, numeric, or special character is represented with a 7-bit binary number (a string of seven 0s or 1s). 128 possible characters are defined. Unix and DOS-based operating systems use ASCII for text files. Windows NT and 2000 uses a newer code, Unicode. IBM's S/390 systems use a proprietary 8-bit code called EBCDIC. Conversion programs allow different operating systems to change a file from one code to another. ASCII was developed by the American National Standards Institute (ANSI).

American Standard Code for Information Interchange (ASCII) 🙄 atoi fn converts ASCII to int (65--91 and 97-122) IMHO

There is also ASCII art. Pictures drawn with just the standard ASCII text symbols. :)
