List all motherboard form factors
ATX- 12 X 9.6in Micro ATX 9.6 X 9.6 in ITX 8.5 X 7.5 in MINI ITX 6.7 x 6.7 in Nano ITX 4.7x4.7 in Pico ITX 3.9 X 2.8 in
cpu
central processing unit
RAM
Random access memory
Rom
read only memory
These provide locations to connect additional components.
expansion slots
This consists of the integrated circuits on the motherboard that control how system hardware interacts with the CPU and motherboard
chipset
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
northbridge
Allows the CPU to communicate with slower speed devices including hard drives, Universal Serial Bus (USB) ports, and expansion slots.
southbridge
backwards compatible with atx mother boards typically use same chipsets
-micro ATX
a small formfactor uses very little power, so fans are not needed to keep it cool
mini- ITX
an AMD CPU layout with the pins under the processor and are inserted using Zero insertion force
pin grid array
an Intel socket type the pins are in the socket instead of on the processor.
land grid array
This architecture uses a relatively small set of instructions. these chips are designed to execute these instructions very rapidly.
RISC( Reduced instruction set computer)
measured in hz
clockspeed
measured in gz
cpu
. The amount of data that a CPU can process at one time depends on the size of the what bus
Front side bus
the width of the fsb is measured in what
bits either 32 or 64
the fsb provides communication between what two components
cpu and memory controller(or northbridge)
also known as the memory controller
northbridge
a technique used to make a processor work at a faster speed than its original specification
overclocking
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.
throttling
performs as though there are two CPUs when multiple threads are being processed.
hyper threading(Intel technology)
a high-speed connection between the CPU and the Northbridge chip.
hyper transport AMD technology
chip can be erased with exposure to UV light. Special equipment is required.
EPROM chip (erasable read only memory)
chip can be erased and re-written without having to remove the chip from the computer.
EEPROM (Electrically erasable programmable read-only memory). also called Flash ROMs.
A type of EEPROM chip
BIOS chip
stores the settings of the bios and is volatile
CMOS
what is volatile memory
memory that is loses its contents without power
powers the CMOS when the computer is off
lithium battery
serial communication
information moving one bit at a time or moving across 1 wire
a path through which a device sends its data so it can communicate
with the CPU and/or other devices.
bus
parallel communication
a group of wires working
in unison that carry data from one
place to another. (typically 8 bits at a time)
update the BIOS by erasing it and rewriting it
