INPUT - Input is the function that obtains data from outside the system.
- This usually involves the user pressing a key, moving the mouse or initiating some other action.
- Their action (input) is converted into a binary electronic signal by the input device.
- This signal is sent to a buffer where it is accessed by the processor. The buffer is a circuit that is part of Random Access Memory (RAM) that allows devices operating at different speeds to
- communicate correctly.
The input may come from a variety of sources including:
• users entering data via a keyboard, mouse, barcode reader or other input device • communication links such as a local area network or the Internet • sensors such as microphones, cameras, temperature sensors, pressure sensors, optical sensors, motion sensors.
Student Activity- Brainstorm in groups of 2 /3 and list as many computer input devices, describing what they are and what they capture as "input".
- We will have a knockout competition - each team giving an item on their list, once you run out or a successful dispute is upheld, then you are knocked out. Last team standing wins!
