Work Search ACCURACY: Computers have reduced the labour involved in mentally intensive and repetitive physical tasks They can also perform tasks that can be dangerous for people to perform on their own. Resources Resources cost money and computers can be programmed to work more efficiently with resources. Technology can also be used to monitor and limit carbon emissions in factories and cars, to keep the air we breathe cleaner. As long as computers have quality programs and quality data, it is extremely accurate. Repeatable accuracy is essential in mass production on assembly lines If the software is correct, the computer can perform the same tasks over and over with 100% accuracy. What aspects ensure that computers are accurate? application programs + data high quality RELIABILITY AD Computers can be relied on to do tasks accurately, without getting tired, getting bored, complaining, or asking for more money. Computers help us to record and use data efficiently. Computers do this by allowing users to work in an organized and competent way. This way a user can get a lot of work done with little effort Efficient data entry is aided by accurate data entry. Accurate data entry is aided by the use of data validation techniques such as input masks and validation rules. Computers process data reliably. As long as users enter the data accurately, the computers can be relied upon to provide accurate output. Computers do not have to take leave for vacations or even. for sleep. The 'garbage in, garbage out' (GIGO) principle refers to the fact that inaccurate inputs will result in inaccurate outputs.
