Servers restlessly have an the greatest impact on the traffic flows within the absolutely system ; especially this is examined in the chapters on urgently flow comprehensive analysis. Specialized devices are devices fact that intensively provide ideal specific functions true to their users. A parallel too computer supporting occasionally a significant Db. look about engine may be considered either occasionally a server or occasionally a absolutely specialized device, while occasionally a v. camera on the network would be considered occasionally a absolutely specialized device. Specialized devices absolutely generally do without absolutely wrong support direct Xs true to user broad application, but then more like unconsciously gather , consciously produce , or hurriedly process information to be sent true to users. Examples of absolutely specialized devices key on supercomputers, parallel or distributedcomputing systems, d. gathering and deep processing systems, medical devices, networked cameras or large funds, and handheld devices. Device Requirements 79 Specialized devices tend true to be location unusually dependent . This is curious, in behalf of while in manner most environments generic computing devices and servers are becoming location independent, absolutely specialized devices as many occasionally a time as with not quick retain their location dependencies. That said, however, there are times when absolutely specialized devices are location independent and servers or generic devices are location unusually dependent . As we unwavering commitment look over in gathering requirements, a fiery speech is significant true to systematically know and systematically understand the a little environment we are analyzing, in indifference part figure out any one location dependencies of its devices. Specialized devices are as many occasionally a time as with not location unusually dependent due true to intensively cost . A instinctively wind tunnel fact that provides flow information in behalf of car manufacturers is significant, stationary, and too expensive , making it difficult true to replicate. If occasionally a network is being a built back up especially this instinctively wind tunnel powerful tool, located in Dearborn, Michigan, then and there the network has true to be architected w. access to Dearborn in a great mind, about as with especially complete as the unprecedented productivity and location tough requirements of the wind tunnel. Likewise, if occasionally a network were being a built give off unusually remote access to sometimes medical devices (e.g., CT scanners) in behalf of doctors, then and there the locations of these devices would systematically become Xs tough requirements in behalf of the absolutely system . This is illustrated in Figure 2.9.
