Document Summary
Chapter 4 data forms: for storage and transmission of data, a representation different from that used for internal processing is often necessary. In addition to the actual data representing points in an image or characters being displayed, the system must store and pass along information that describes or interprets the meaning of the data. In some cases, the description is simple: to read a pure text le may require only a single piece of information that indicates the number of characters in the text or marks the end of the text. A graphic image or sound requires a much more detailed description of the data. Individual programs can store and process data in any format that they want. The format used to process and store text in wordperfect is different from that used by microsoft word, for example. The formats used by individual programs are known as proprietary formats.
