the design phase factors to be considered when desiging the output requirements,”in a top down approach to a system design, the programmer will start by idefntifiying the output that the system will need to produce. There are a number of possible output formats that must be considered including such items as printer, screen, plotter, audio, email links to webpages, autmated fax facilities, and computer output microfilm. THere are many more possible output devices that could be incorporated into any system-it will depend on the tehcnology that is available to the developers. There are sound reasons for starting the system development with the diesign of the output, The system will be implemented to help improve effectviness or to solve a problem. In order to do this the first step will be to determine what can be done to help the situation. Once this has been done, a clear picture of what has to be provided can be identided. This will shape the output requirements of the system. while the output may seem to be the last part of the system they should be developed. It should not be. In order to make the system a success it must be able to produce the outcomes that can solve the problem, therefore the output required needs to be identified early in the process. Once the output has been identified it will place constaits on the system. These constraits will include requirements of data to be collected to procude the output and to the limitations imposed by the technologies used to create the output. While it may sound minor the manner in which output is to be created and/or displayed is actually of great significance to the design of a computer system. This is becuase it can quickly change the nature of the resources that are reuqired by the system to produce the output. For example, if the system is to collect pictures that are displayed over the web then the file size will not have to be as large as those printed. SOme of those major constaits on output include:printers-print quality e.g. laser inkjet/color and the nature of the information to be produced for example if a recipt is to be printed and needs to be made in duplicate then an impact printer will need to be used or the item printed twice. Screen if the output is primarily to be screen based then the scree nwill impose a number of limitations on the output. THe output will need to be designed to fit into the screen size. If the screen is onochrome
then color cannot be used etc. In the design phase it is usual practice for prgrameers to begin by identifying the output requrment of the proposed system. There are a number of output devices that cna be incorporated into any systemconsider why the manner in which oput is to be created and/or displayed is acutalyy of great significance to the design of a computer system. if output is primarily screen based the nthe dimensions of the output scree nis a determining factor and must be considered when designing output. If the system is to collect pcitures that are displayed over the web then the file size will not have to be as large as those that will be printed.”
