Computer Timer is like a timer used for cooking. It may be used for timing cooking and for other purposes. For example, you might use it either to help you not miss an appointment or to be alerted immediately before you intend to do something, e.g., taking medicine or do-ing something not so important such as tuning in a radio show. If you know when you plan to do something, set the timer to sound a minute or so before the event, and it should alert you. If you have Internet service that costs more when you use it a longer period of time, you may set Computer Timer to sound when you would like to log off the network, or if applica-ble, when you will be required to pay more (when you log on to the Internet, determine the amount of time that you may use the network and not have to pay more, and then set the timer to sound immediately before your service will cost more).
