(1) A tiny crystal in your computer that sends out a regular signal hundreds of thousands of times every second. It's used by all the electronic components to keep in time with each other so that data is not lost when it's transferred. The central processing unit normally carries out one instruction every clock pulse, so the faster the clock the more instructions it carries out. The speed of a processor, and so the clock, is measured in megahertz (MHz), which represent one million pulses every second. A procesor that runs at 50MHz uses a clock that sends 50 million signals every second.
(2) Windows 3.1 includes a utility called Clock that displays the current time in a window or as an icon. To start the utility, double-click on the Clock icon in the Accessories group. Windows 95 displays the time in the bottom right-hand corner of the screen. To see the date, move the pointer over the time and wait a couple of seconds, then the data will pop up. To change how the time is displayed in Windows 95, move the pointer over the time display and click on the right-hand mouse button.
