APPLICATION OF A DATA COMPRESSION TECHNIQUE TO THE AMERICAN STANDARD CODE FOR INFORMATION INTERCHANGE (ASCII)

Abstract:
A coded character set (CCS) provides the means by which the act of moving and storing data, as well as arithmetic and logical processing, is accomplished by a digital computer system (DCS). A CCS has a rich algebraic and discrete structure in that it can be considered as a set, a code and a sequence. It is therefore amenable to the basic theorems and results on sets, codes and sequences. As a set/code, it can be compacted (i.e., reduced in size) by developing and applying an appropriate presentation technique similar to the concept of group presentation in combinatorial group theory. In this paper, a presentation technique for binary uniform digital code, called ‘code presentation’, is applied to the (7-bit) American Standard Code for Information Interchange, a subset of the Unicode Standard. This code is the most popular coded character sets used on DCSs. Novel structural characteristics of the CCS are deduced. |
