Input Devices are simply the pieces of equipment you use to get information or data into a computer.
They can require a user to make them work, such as a keyboard, or can be completely automatic, for example a light sensor such as those found on lamp posts to make the lights come on when the light level drops.
Every input device has the same basic approach - they transform user actions or commands into electronic signals that are understood by computers.
A device detects an input (such as a key press), and it sends a signal containing the data into the processors.
