Description
ASCII stands for "American Standard Code for Information Interchange". It was designed (invented) in the 60’s. It was a standard character-set for computers and hardware devices like teleprinters and tapedrives. It contains the numbers from 0-9, the uppercase and lowercase English alphabets from A to Z, and some special characters.
Now the special characters (device control characters) have code positions from 0 to 31. These special characters are not displayed or seen by the user. Printable characters have code position numbers from 32 to 126. Note: the DELELTE device (keyboard) control character has code position number, 127. So the ASCII character set has a total of 128 characters.
As you will see below, none Anglo-Saxon characters (printable) are not found in the set. Today there is a lot of international businesses. So there is need for broader character sets. I will talk about the two most important in the next part of the series. For now, glance through the ASCII lists below :
