An input apparatus or keypad (14) for computers and networks is provided. The keypad (14) has a palm size housing (20) having an extended opening (30) in its top surface (28). An input or key assembly (32) mounted in the opening (30) has a number of keys (34) arrayed in a 6 by 4 matrix, for example, to which operator can access to input information. The housing (20) includes a processor for processing information input using keys into a corresponding signal, and a transmitter for transmitting the resultant signal to a receiver of the computer or network by wireless. In particular, the keypad (14) is designed ergonomically so that the operator can learn an input operation with ease and time-consuming and push keys so quickly.
