describe the operation of the w4 comn two elements upon which the w4 comn is built must first be introduced real world entities and information objects these distinction are made in order to enable correlations to be made from which relationships between electronic logical objects and real objects can be determined a real world entity rwe refers to a person device location or other physical thing known to the w4 comn each rwe known to the w4 comn is assigned or otherwise provided with a unique w4 identification number that absolutely identifies the rwe within the w4 comn rwes can interact with the network directly or through proxies which can themselves be rwes examples of rwes that interact directly with the w4 comn include any device such as a sensor motor or other piece of hardware that connects to the w4 comn in order to receive or transmit data or control signals because the w4 comn can be adapted to use any and all types of data communication the devices that can be rwes include all devices that can serve as network nodes or generate request and or consume data in a networked environment or that can be controlled via the network such devices include any kind of u201c dumb u201d device purpose designed to interact with a network e g cell phones cable television set top boxes fax machines telephones and radio frequency identification rfid tags sensors etc typically such devices are primarily hardware and their operations can not be considered separately from the physical device examples of rwes that must use proxies to interact with w4 comn network include.
