Question 3

RAM

Answer 3

Random access memory

Question 4

Rom

Answer 4

read only memory

Question 5

These provide locations to connect additional components.

Answer 5

expansion slots

Question 6

This consists of the integrated circuits on the motherboard that control how system hardware interacts with the CPU and motherboard

Answer 6

chipset

Question 7

Controls high speed access to the RAM and video card. It also controls the speed at which the CPU communicates with all of the other components in the computer

Answer 7

northbridge

Question 8

Allows the CPU to communicate with slower speed devices including hard drives, Universal Serial Bus (USB) ports, and expansion slots.

Answer 8

southbridge

Question 9

backwards compatible with atx mother boards typically use same chipsets

Answer 9

-micro ATX

Question 10

a small formfactor uses very little power, so fans are not needed to keep it cool

Answer 10

mini- ITX

Question 11

an AMD CPU layout with the pins under the processor and are inserted using Zero insertion force

Answer 11

pin grid array

Question 12

an Intel socket type the pins are in the socket instead of on the processor.

Answer 12

land grid array

Question 13

This architecture uses a relatively small set of instructions. these chips are designed to execute these instructions very rapidly.

Answer 13

RISC( Reduced instruction set computer)

Question 14

measured in hz

Answer 14

clockspeed

Question 15

measured in gz

Answer 15

cpu

Question 16

. The amount of data that a CPU can process at one time depends on the size of the what bus

Answer 16

Front side bus

Question 17

the width of the fsb is measured in what

Answer 17

bits either 32 or 64

Question 18

the fsb provides communication between what two components

Answer 18

cpu and memory controller(or northbridge)

Question 19

also known as the memory controller

Answer 19

northbridge

Question 20

a technique used to make a processor work at a faster speed than its original specification

Answer 20

overclocking

Question 21

a technique used when the processor runs at less than the rated speed to conserve power or produce less heat. typically used in laptops or mobile devices.

Answer 21

throttling

Question 22

performs as though there are two CPUs when multiple threads are being processed.

Answer 22

hyper threading(Intel technology)

Question 23

a high-speed connection between the CPU and the Northbridge chip.

Answer 23

hyper transport AMD technology

Question 24

chip can be erased with exposure to UV light. Special equipment is required.

Answer 24

EPROM chip (erasable read only memory)

Question 25

chip can be erased and re-written without having to remove the chip from the computer.

Answer 25

EEPROM (Electrically erasable programmable read-only memory). also called Flash ROMs.

Question 26

A type of EEPROM chip

Answer 26

BIOS chip

Question 27

stores the settings of the bios and is volatile

Answer 27

CMOS

Question 28

what is volatile memory

Answer 28

memory that is loses its contents without power

Question 29

powers the CMOS when the computer is off

Answer 29

lithium battery

Question 30

serial communication

Answer 30

information moving one bit at a time or moving across 1 wire

Question 31

a path through which a device sends its data so it can communicate with the CPU and/or other devices.

Answer 31

bus

Question 32

parallel communication

Answer 32

a group of wires working in unison that carry data from one place to another. (typically 8 bits at a time)

Question 33

update the BIOS by erasing it and rewriting it

Answer 33

flashing
