Hardware used in my created system Essay Example for Free

Hardware used in my created system moveThe sonorousware my system bequeath use is a keyboard and mouse for input and it will use a monitor and a printer for output. The actual computer tower itself is obviously required ironware, and includes a hard drive, RAM for process storage, the CPU to run all the processes in the computer and there are different things too. The lock shimmy is my output product (as well as the leaflet), as it is what I want to communicate out of my system. The input is the data in the spreadsheet, and the spreadsheet is obviously the store of this data.The process itself is getting the input to the output, and the track we do that is by exploitation mail merge. Mail merge automatically moves the data from where we input it into our earnings slip which will be printed, which is our output. Each part of my system needs hardware. The input which is the data requires a keyboard. Storage requires a hard drive, obviously. The process requires a CPU an d RAM to function and the output ( earnings slip) requires a printer monitor. My system can be described as a number of subsystems.The wage slip is a system in itself, having the spreadsheet as input data and storage, the actual mail merge universe the process then the wage slip being your output. But deeper down, the spreadsheet alone is a system, with data entered in as input, the cells storing the data. Then the processes are the formulas manipulating the data, finally giving us wage figures as our outputs from the spreadsheet sub-system. The problem with the hardware I am using is that with a keyboard and mouse, lots of errors can be made, even with validation rules. soul may type a 7 in hours instead of 8 and then that employee would get underpaid. A better system would be to use a card digital scanner, fingerprint scanner or barcode scanner with recognition of each employees card/fingerprint. A person could scan in when they enter the work couch and then rescan back out a nd then the data of how many hours they had worked could automatically enter into the spreadsheet, therefore qualification error almost impossible. The problem with this is that there is a larger initial cost for the technology take over a mouse and keyboard input.There are also completely different systems like using save and paper The upside of this is that its extremely cheap as no expensive hardware or software is needed. There are many downsides to this system though. First of all, it is very slow, as each wage slip must be written out individually and all calculations have to be make by hand and then written down. Furthermore, lots of errors can be made using pen and paper because the calculations arent as consistent as using some kind of computer.Hand writing may be misread on the calculations and then it could make catastrophic mistakes when copying out the calculation results onto the wage slip. Writing each wage slip out would take so much time that it believably woul dnt even be feasible in this day and age. Automated wage slips overcome this problem commercial-grade systems are normally very accurate but theyre made for very large scale operations, and so cost a lot of money. Also, our system uses very basic hardware that any computer will have, and can be adapted to the users needs.
