computer
a programmable device that takes in data, processes that data and then outputs some data
egs of inputs processes outputs
INPUT: e.g. via keyboard, mouse, temperature sensor, barcode scanner, light detector etc. PROCESS: to change the meaning or format of some data, e.g. to perform a mathematical calculation, to sort a list alphabetically, to encrypt a message, to search for an item of data. Processing involves algorithms. OUTPUT: often via a screen, but could also be (e.g.) switching off heating and lights, sending more fuel to an engine, sending your bank details over the Internet, setting off an alarm. Sometimes the output results may be fed back into the computer as new input for further processing.
