Explain what an event is in the context of event - driven programs. Give two examples.

An event is an actinin that causes the program to perform a type of processing in response to an action. One example would be clicking on a Display Bank Balance on a GUI.

This triggers another event to clear out or restore the page to what it originally was

Give examples of the differences between an input operation and an output operation.

An input operation is something that can be stored to RAM and then displayed on screen. Examples of this would be a keyboard, digital camera or scanner. The Output operation is information that is stored in RAM, is displayed as a output. Examples are a printer and monitor.
