内容説明
About 95% of all data transmission consists of blanks, strings of spaces, numeric and alphabetic repetitions, not only buzzing through the airways but also embedded in a large number of data bases. In this book the author shows how to increase the efficiency and cut the cost of data transmission and storage through the application of practical data compression routines. Written as a no-nonsense, practical guide for implementing data compression, the techniques given in this book will prove invaluable whether your organisation is large or small, whether you use a mainframe or microcomputer and whether you are an end- user or an equipment designer. Also included are IBM PC programs and routines to compress and decompress data and to analyze the susceptibility of data to compression. The programs are also available on disk for those who prefer to save time and the introduction of errors.
