Voltages provided by ATX PS.	3.3V, 5V, 12V, -12V
How many 12V rails on ATX PS?	One for processor and one or more for drives, fans, etc.
Name the voltages provided by Molex.	5V & 12V
Name the voltages provided by SATA.	3.3V, 5V, 12V
Motherboards: Largest and most common (12 X 9.6”). Used since 1995. Standard ‘full-size’ motherboard.	ATX
Motherboards: Come in several different SFF sizes. Consume very little power and do not require fans for cooling.	ITX
Fire Safety: Combustible Metals	Class D
Motherboards: Small boards designed for smaller devices, DVRs and set top boxes. (4.7 x 4.7”)	Nano ITX
Fire Safety: Ordinary combustibles such as paper and wood.	Class A
Motherboards: Smaller version of ATX and very popular with desktop computers. It’s the board that comes in varying sizes (6.75 x 6.75” to 9.6 x 9.6”)	Micro ATX
Fire Safety: Electrical fire. Remove power source. <never use water>	Class C
Motherboards: Extremely small boards are embedded in mobile devices. (3.9 x 2.8”)	Pico ITX
Fire Safety: Flammable liquids and gasses.	Class B
Motherboards: For use in home theatre systems. Will fit into any case with ATX mount points. (6.7 x 6.7”)	Mini ITX
Connection between CPU and internal cache memory	Back Side Bus
Expansion Slots: 32 & 64-bit verisons. Speeds up to 533 MB/s. Frequencies are 33 or 66 Mhz. Voltage can be 3.3v or 5v.	Peripheral Component Interconnect (PCI)
Expansion Slots: This type of expansion slot uses serial communication (data sent in byte streams), there is no external clock signal and can have multiple two-way lanes which allow the device to send and receive data at the same time.	PCI Express (PCIe)
Expansion Slots: For laptop expansion cards. 32-bit with 33MHz bus.	Mini PCI
This connects the CPU in newer chipsets in place of the front side bus.	Direct Media Interface Bus (DMI)
Expansion Slots: Legacy port for graphics cards.up to 2133 MB/s without competing with other PCI device data transfers. Always 66MHz	Accelerated Graphics Port (AGP)
CPU Chipsets: Also called memory controller hub (MCH) is the primary interface for high-speed devices such as the CPU, RAM and a dedicated graphics slot. On newer processors, the _________ bridge functions have been taken over by the CPU.	North Bridge
Expansion Slots: Improvement on PCI reaching up to 1064MB/s. Not commonly used on desktop systems, although they were once used in some servers.	PCI extended (PCI-X)
Expansion Slots: PCIe slot for laptop computers.	Mini PCIe
Connection between CPU and supporting chipset on motherboard.	Front Side Bus (FSB)
Expansion Slots: Primary standard in use today, replaces PCI, AGP and PCI-X on many motherboards. Can reach speeds up to 2GB/s on multiple lanes simultaneously	PCI Express (PCIe)
CPU Chipsets: The ________ bridge provides an interface to low speed devices and is also called the I/O controller hub (ICH).	South Bridge
Name for Intel hardware assited virtualization feature.	VT-x
Name for AMD hardware assisted virtualization.	AMD-V
RAM: Uses double pumping to double the data rate of SDRAM.	DDR RAM (Double Data Rate)
RAM: Doubles the data rate of DDR2. It can transfer 4x the data of DDR and 8x that of SDRAM.	DDR3
RAM: Doubles the data rate of DDR. In addition to double pumping, it modifies the way that data is processed and can transfer twice as much data as DDR SDRAM.	DDR2
This RAM uses switching circuitry rather than capacitors and can hold a charge without a constant refresh. It requires more components per bit making it more expensive, however it’s quicker than DRAM.	SRAM (Static RAM)
Dynamic RAM synchronized with a clock for faster speeds.	SDRAM (Synchronous Dynamic RAM)
Number of Pins on DDR DIMM	184
Number of Pins on DDR2 SODIMM	144 OR 200

Number of Pins on DDR3 DIMM	240
Another name for LGA 775	Socket T
ATA Max Speeds (ATA-4, 5, 6, 7)	33MB/s, 66MB/s, 100MB/s, 133MB/s respectively
SATA I - Max Speed	1.5 Gb/s or 150 MB/s
SATA III - Max Speed	6.0 Gb/s or 600 MB/s
Another name for LGA 1156	Socket H (or H1)
USB 2.0 maximum transfer rate	480 Mb/s
Another name for LGA 2011.	Socket R
SATA II - Max Speed	3.0 Gb/s or 300 MB/s
