6. Input Processing Output Storage Typing or tapping a message on a keyboard Download an app, doc or photo Viewing a document, photo or website using a monitor Storage is saving of data to a disk space Using a voice command Move data from one drive to another Listen to a live or recorded class or song Data is written to the machine’s drive, an external drive, network or cloud storage Clicking the send button Performing programming tasks and computations Print document or file for later use Data remains indefinitely unless you apply an expiration date or delete the data Entering program commands Change raw data into usable formats Output makes the data apparent and useful Storage saves data for reuse Processing happens when the computer receives the input and converts that data into a format that users can recognize and use
