Output devices decode the data into information that can be easily understood by people, which are ultimately the users of a computer. This way, the computer system may be viewed as no more than a data processing system.
As far as electromechanical engineering technology is concerned, it enables engineers to design automated systems. Students need to learn to use computers, math, and advanced science in order to design such systems. Learning how to install and test robotics equipment is also important, and is performed by using computers.
Even apparently simple devices, such as candy machines, involve various technologies. For instance, the little rollers (a mechanical device) pull the coin or the bill in. Afterwards, a scanner, which is an optical and electronic device, reads the bill or coin to make sure it is not fake. Finally, when the user makes a selection, an electronic device performs the task of calculating how much change to...
