    摘要: A data system and method for retrieving information from a particular address of a computer network using a collection of bar code symbols and a hand-held, portable terminal. Each of the bar code symbols of the collection includes encoded data that is associated with a particular computer network address. The hand-held, portable terminal comprises a reading unit including a laser scanner or a CCD array, a communications unit, and a display. In operation, the reading unit scans or images a bar code symbol from the collection, the communications unit establishes a connection to the computer network and accesses the computer network address associated with a particular bar code symbol, and information stored on the computer network at a location associated with the network address is transferred to the terminal and displayed on the display.
