ASCII

Short for American Standard Code for Information Interexchange, ASCII is an industry standard, which assigns letters, numbers and other characters within the 256 slots available in the 8-bit code. The ASCII table is divided in 3 sections: Non printable system codes between 0 and 31. "Lower ASCII" between 32 and 127. This part of the table originates from older, American systems, which worked on 7 bit character tables. Foreign letters, like Ø and Ü were not available then. Shown Below. "Higher ASCII" between 128 and 255. This part is programmable, in that you can exchange characters, based on which language you want to write in. Foreign letters are placed in this part. Shown Below. The following is the Standard ASCII Characters.

The original ASCII defines the codes for the average letters and numbers used by computers. Extended ASCII defined extra characters, such as a special symbols, foreign language letters, or drawing characters. The following is the Extended ASCII Characters.
