WHAT IS A FORM? CLASSIFICATION OF FORMS

The first step in systems design is to design output and input within predefined guidelines, In input design, user-originated inputs are converted to a computer-based format. It also includes determining the record media, method of input speed of capture, and entry into the system, Online data entry accepts commands and data through a keyboard, The data (input or output) are displayed on a cathode ray tube (CRT) screen for verification, The major approaches to input design are the menu, the formatted, and the prompt design, In each alternative, the user's options are predefined,

In output design, the emphasis is on producing a hard copy of the information requested or displaying the output on a CRT screen in a predefined format. Form design elaborates on the way output is presented and the layouts available for capturing information.
