Explain the ASCII Character Set?
Most programming languages have a means of defining a character as a numeric code and, conversely, converting the code back to the character. ASCII (American Standard Code for Information Interchange) a coding standard for characters, numbers, and symbols that is the same as the first 128 characters of the ASCII character set but differs from the remaining characters.
The ASCII (American National Standard Code for Information Exchange) character set (excluding the extended characters defined by IBM) is divided into four groups of 32 characters.
The first 32 characters (American National Standard Code for Information Exchange) ASCII codes 0 through 1Fh, form a special set of non-printing characters called the control characters. We entitle them control characters because they perform various printer/display control operations rather than displaying symbols.
