The present invention relates to a communication system and method, an information processing terminal and method, and an information processing apparatus and method which enable very suitable confirmation of details of an operation. In a PDA 11, an exterior image of a terminal is prepared as characteristic information representing characteristics of the PDA 11. Also, in the PDA 11, communication establishing information for establishing predetermined wireless communication with a personal computer 1 is prepared, and a built-in reader/writer 12 transmits both types of information to a reader/writer 2 of the personal computer 1. The personal computer 1 establishes wireless communication with the PDA 11 based on the communication establishing information, and controls a display unit 3 to display an exterior image of the PDA 11 based on the characteristic information while performing the establishing processing. The present invention can be applied to various types of information processing apparatuses such as personal computers and PDAs.
