DDRIII:
In electronic engineering, DDRIII or double-data-rate three synchronous dynamic random access memory is a random access memory interface technology used for high bandwidth storage of the working data of a computer or other digital electronic devices. DDR3 is part of the SDRAM family of technologies and is one of the many DRAM (dynamic random access memory) implementations. DDR3 SDRAM is an improvement over its predecessor, DDR2 SDRAM, and the two are not compatible. The primary benefit of DDR3 is the ability to transfer at twice the data rate of DDR2 (I/O at 8× the data rate of the memory cells it contains), thus enabling higher bus rates and higher peak rates than earlier memory technologies. In addition, the DDR3 standard allows for chip capacities of 512 megabits to 8 gigabits, effectively enabling a maximum memory module size of 16 gigabytes. |
PCI-Express [x16] & [x1]:
PCI Express (Peripheral Component Interconnect Express), officially abbreviated as PCIe (or PCI-E, as it is commonly called), is a computer expansion card standard designed to replace the older PCI, PCI-X, and AGP standards. PCIe 2.1 is the latest standard for expansion cards that is available on mainstream personal computers. PCI Express is used in consumer, server, and industrial applications, as a motherboard-level interconnect (to link motherboard-mounted peripherals) and as an expansion card interface for add-in boards. A key difference between PCIe and earlier buses is a topology based on point-to-point serial links, rather than a shared parallel bus architecture. |

Express Card:
The Express Card is an interface to allow peripheral devices to be connected to a computer. The Express Card standard is implemented as one or more slots built into, usually, a portable computer, and cards to be inserted into a slot and containing electronic circuitry and connectors to which external devices can be connected. The ExpressCard standard replaces the PC card (also known as PCMCIA or CardBus) standards. ExpressCard plug-in hardware available includes TV tuners, mobile broadband cards, FireWire 800 (1394B), Serial ATA external disk drives, solid-state drives, wireless network interface cards, TV tuner card common access card (CAC) reader and soundcards. Media remote control units are available that use the ExpressCard slot to store and recharge.

Compact Flash:
A CompactFlash (CF) is a mass storage device format used in portable electronic devices. For storage, CompactFlash typically uses flash memory in a standardized enclosure. The format was first specified and produced by SanDisk in 1994. The physical format is now used for a variety of devices. CompactFlash became the most successful of the early memory card formats, outliving Miniature Card, SmartMedia, and PC Card Type I in mainstream popularity. The memory card formats that came out after the introduction of CompactFlash, such as SD/MMC, various Memory Stick formats, xD-Picture Card, offered stiff competition. Most of these cards are significantly smaller than CompactFlash while offering comparable capacity and read/write speed. Professional memory cards, such as P2 and SxS, are physically larger, faster, and significantly more expensive.

Line-in:
A type of connector found on audio devices to attach a device, such as a microphone, for recording audio. Line-in can be analog or digital.

|
Line-Out:
A type of connector found on audio devices to attach a device, such as a microphone, for receiving audio. Line-out can be analog or digital.

MTBF (Hours):
Mean time between failures (MTBF) is the predicted elapsed time between inherent failures of a system during operation. [1] MTBF can be calculated as the arithmetic mean (average) time between failures of a system. The MTBF is typically part of a model that assumes the failed system is immediately repaired (zero elapsed time), as a part of a renewal process. This is in contrast to the mean time to failure (MTTF), which measures average time between failure with the modeling assumption that the failed system is not repaired. The definition of MTBF depends on the definition of what is considered a system failure. For complex, repairable systems, failures are considered to be those out of design conditions which place the system out of service and into a state for repair. Failures which occur, can be left or maintained in an unrepaired condition, and do not place the system out of service, are not considered failures under this definition. In addition, units that are taken down for routine scheduled maintenance or inventory control, are not considered within the definition of failure.
