Ctrl and Alt are what are known as modifier keys. By themselves, or pressed together, they will do nothing.
Their purpose is to change the action of another key to perform a different task. For example, the Delete key is usually used to delete a selection of text from a document.
When pressed together with Ctrl and Alt, however, they trigger a keyboard interrupt to either reboot the computer or invoke a task manager on an operating system.
