What is considered an input and output peripheral?

An input is any device that can put information into a computer, (keyboard, mouse, microphone, etc.) An output will take information out, (monitor, printer, speaker, etc.)

a macro is a tool that allows you to automate tasks and add functionality to your forms, reports, and controls. for example, if you add a command button to a form, you associate the button's onclick event to a macro, and the macro contains the commands that you want the button to perform each time it is clicked.
