give something to the computer, in other words, when a computer or device is receiving a command or signal from outer sources, the <a href="/wiki/Event_(computing)" title="Event (computing)">event</a> is referred to as input to the device. </p><p>Some computer devices can also be categorized as <a href="/wiki/Input_device" title="Input device">input devices</a> <sup id="cite_ref-1"
