Introduction to Computer Studies
Intermediate  - Secondary

Using extensive original graphics and photography to illuminate fundamental concepts of computer technology, Part I begins by explaining the principles of binary coding that allow electrical current to represent information, then goes on to describe the basic types of computer circuits that are used to store, transmit, and manipulate this coded information.

Illustrating the many ways in which computerized information is used in business by analyzing the data system of a major department store, Part II begins with the input of information at the point-of-sale terminal, and describes how this information becomes part of a data base, the ways in which this data-based information can then be processed, and the applications of the processed information.
