Input (computer science)

In <a href="/facts/Computer_science/lN3pEyPz">computer science</a>, the general meaning of input is to provide or 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="/facts/Event_(computing)/0YdM6AoB">event</a> is referred to as input to the device.
Some computer devices can also be categorized as <a href="/facts/Input_device/TXYLUkux">input devices</a>, because devices are used to send instructions to the computer, some common examples of computer input devices are:

<ul><li><a href="/facts/Mouse_(computing)/fJpa1tUE">Mouse</a></li>
<li><a href="/facts/Keyboard_(computing)/MczF9LIS">Keyboard</a></li>
<li><a href="/facts/Touchscreen/zpSKDFpe">Touchscreen</a></li>

<li><a href="/facts/Image_scanner/7DEJFTwx">Image scanner</a></li>
<li><a href="/facts/Trackball/wr6XIp1x">Trackball</a></li></ul>
Many <a href="/facts/Computer_parts/8jSjsCNv">internal components of computer</a> are input components to other components, like the power-on button of a computer is an input component for the <a href="/facts/Central_processing_unit/Jxp1bqMV">processor</a> or the <a href="/facts/Power_supply_unit_(computer)/3nvssXFG">power supply</a>, because it takes user input and sends it to other components for further processing.
In many computer languages the keyword "input" is used as a special keyword or function, such as in <a href="/facts/Visual_Basic/7QMXM6fP">Visual Basic</a> or <a href="/facts/Python_(programming_language)/YbuGqofa">Python</a>. The command "input" is used to give the machine the data it has to process.
