Data conversion is the conversion of computer data from one format to yet another. Throughout a computer environment, data is encoded in a variety of ways. For instance, computer hardware is built on the basis of certain standards, which often requires that facts contains. Similarly, the operating system is predicated about certain standards with regard to data conversion and report handling. Furthermore, each computer plan handles data in the different manner. Whenever any one of those variable is altered, data must be converted somehow before it can be used by a unique computer, operating system or program.
