| 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 DDR SODIMM | 200 |
| Number of Pins on DDR3 SODIMM | 204 |
| 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 |
