Question | Answer |
---|---|
adapter card | A small circuit board inserted in an expansion slot and used to communicate between the system bus and a peripheral device. Also called an interface card. |
binary number system | The number system used by computers; it has only two numbers, 0 and 1, called binary digits, or bits. |
BIOS | Firmware that can control much of a computer–s input/output functions, such as communication with the floppy drive and the monitor. |
BIOS setup | BIOS setup – The program in system BIOS that can change the values in CMOS RAM. Also called CMOS setup. Bit – A 0 or 1 used by the binary number system. |
bus | The paths, or lines, on the motherboard on which data, instructions, and electrical power move from component to component. |
byte | A collection of eight bits that can represent a single character. |
cards | Adapter boards or interface cards placed into expansion slots to expand the functions of a computer, allowing it to communicate with external devices such as monitors or speakers. |
CPU | Also called a microprocessor or processor. The heart and brain of the computer, which receives data input, processes information, and executes instructions. |
chipset | A group of chips on the motherboard that controls the timing and flow of data and instructions to and from the CPU. |
clock speed | The speed, or frequency, expressed in MHz, that controls activity on the motherboard and is generated by a crystal or oscillator located somewhere on the motherboard. |
CMOS | The technology used to manufacture microchips. CMOS chips require less electricity, hold data longer after the electricity is turned off, and produce less heat than earlier technologies. The configuration or setup chip is a CMOS chip. |
CMOS RAM | Memory contained on the CMOS configuration chip. |
CMOS setup | The program in system BIOS that can change the values in CMOS RAM. Also called BIOS setup. |
data bus | The lines on the system bus that the CPU uses to send and receive data. |
data path size | The number of lines on a bus that can hold data, for example, 8, 16, 32, and 64 lines, which can accommodate 8, 16, 32, and 64 bits at a time. |
DIMM | A miniature circuit board installed on a motherboard to hold memory. DIMMs can hold up to 4 GB of RAM on a single module. |
