ASCII EncodingASCII stands for American Standard Code for Information Interchange. It is a standard numerical coding used by almost every computer that assigns numbers to every symbol and character that can be inputted or outputted. (That includes lower and upper case letters, numbers, punctuation signs, and other symbols.) In decimal ASCII, every symbol and character corresponds to a number written in base 10 (that is, our everyday notation for numbers). There also exists a binary ASCII notation, which uses only the binary numbers we saw in Lab 1, which have only 1's and 0's in their digits. A computer displays and relates information in terms of ASCII character codes, but in the end only the actual binary translation is what the computer uses. For historical reasons 127 numbers were used to assign symbols to (127 is the biggest number you can have using only seven digits in binary notation). The order of characters in ASCII code is as follows:

You can practice ASCII encoding below. Please, input decimals without leading zeros, and put exactly one space between decimals. Example: "Math Alive!" is encoded as "77 97 116 104 32 65 108 105 118 101 33". After typing in your answer, press return to see if you are correct:
