What does PAD mean?
2.PAD, the abbreviation of problem analysis diagram, is another graphical representation tool proposed by Ryuhiko Ercun and others in Japan from 1974, which is mainly used to describe the detailed design of software. Like block diagrams, PAD diagrams can only describe several basic structures that structured programs are allowed to use.

Users can enter text through the built-in handwriting recognition, on-screen soft keyboard, voice recognition or real keyboard (if the model is equipped).
