The first section introduces the basic concepts of number systems, storage of numerical data, and machine arithmetic. Chapters on the Intel math unit architecture, data conversions, and the details of math unit programming establish a framework for developing routines in engineering and scientific code. The second part, entitled Application Development, covers the implementation of a C++ program and flowcharting. A tutorial on Windows programming supplies skills that allow readers to create professional quality programs.
Many of the
techniques that have been developed have already been used to study the extent and
distribution of variation in species gene-pools and to investigate evolutionary and
taxonomic relationships among plant populations. With the development of the
polymerase chain reaction (PCR) based techniques, in particular, numerous molecular
technologies have been, and still are being, developed, which can be used for the
detection, characterization, and evaluation of genetic diversity in plant populations.
Data and the Binary Code System
‘Data’, a plural noun, the term used to describe information which is storedand processed by is in computers. It is essential to know how such data are represented electronically before we can begin to understand how it can be communicated between computers, communication devices (e.g. facsimile machines) other data storage or devices. As a necessary introduction to the concept of ‘digital’ transmission, this chapter is devoted to a description of tha method of representing textual and numeric information which is called the ‘binary code’.
