Main system board The circuit board inside your computer containing the circuitry and components your computer needs to operate. Math coprocessor A device that enables the computer to process mathematical calculations faster by using floating point numbers instead of whole numbers. Megabyte (MB) A unit used to measure storage space in a computer's memory or on a disk. One megabyte equals 1024KB (kilobytes). Megahertz (MHz) A unit used to measure oscillation frequency, such as that of a computer's internal clock. A megahertz is one million cycles per second. Memory module A small circuit board, commonly called a SIMM (single inline memory module), that contains surface-mounted memory chips. You can add memory modules to the main system board to expand your computer's memory. Microprocessor A small CPU on one semiconductor chip. See also CPU. Numeric keypad The number and cursor control keys grouped together on the right side of the keyboard. The operation of the dual-use keys on the numeric keypad is controlled by the NumLock key.
