The circuit board assembly includes an expansion card which is operatively connected to the expansion slot and includes a connector carried on one end thereof. \nThe end of the expansion card having the connector is located adjacent the periphery of the computer case. An extension circuit board is provided and is constructed and arranged to operatively mate with the connector on the expansion card. The extension circuit board extends beyond the periphery of the computer case, and may include multiple ports thereon for connecting peripheral devices to the computer. The extension circuit board is contained within an RF shielding container and is secured to the computer housing.

FSB = Front Side Bus\nIt is the connection between the CPU, memory, and other system components.\n\nPCI = Peripheral Component Interconnect\nIt is an technology that allows user to expand the functionality of their computer.  It is usually expressed as a "PCI Slot" (the connector on the computer) whereas "PCI cards" deliver the functionality.  For example, there are PCI sound cards, PCI network cards, PCI TV tuner cards, etc.\n\nSATA HDD = Serial Advanced Technology Attachment Hard Disk Drive\nA hard drive that uses serial technology instead of parallel.  On a consumer level, it just means that the connection from the hard drive to the motherboard has changed.  It use to be parallel or PATA.  On an engineering level, the communication isn't sent in parallel fashion (several bits wide but at slow rate) but in a serial fashion (narrow width but at higher rate).\n\nBays = Probably means optical drive bay\nIn computer cases there are references to "bays".  Bays are another means to extend functionality of the computer and they come in two types: 5.25" and 3.5" bays.  5.25" bays can accomodate optical drives such as CDROMS, DVD, CD burners, and other wide products.  3.5" bays were originally designed for floppy drives but can hold anything that can fit in that bay.\n\nDMI = Desktop Management Interface\nMostly used in the workforce.  Allows system administrators to know what kind of software and hard is installed on the computer.\n\nUSB = Universal Serial Bus\nAgain, another expansion technology but is more external compared to PCI technology (which is internal to the computer).  Common uses of USB devices are USB mouse, USB web cameras, USB scanners, USB printers, USB CD burners, etc.

it's a standard that manages the power supply of monitors for computers through the video adaptor. for exemple, after some time, the adaptor switches off a signal (horizontal or vertical or combination) and the monitor goes to stand-by

PCI - Short for Peripheral Component Interconnect, a local bus standard developed by Intel Corporation. Most modern PCs include a PCI bus in addition to a more general ISA expansion bus. PCI is also used on newer versions of the Macintosh computer. \nPCI is a 64-bit bus, though it is usually implemented as a 32-bit bus. It can run at clock speeds of 33 or 66 MHz. At 32 bits and 33 MHz, it yields a throughput rate of 133 MBps. Also see PCI-X and PCI Express. \nAlthough it was developed by Intel, PCI is not tied to any particular family of microprocessors.\n\nDigitizer\nTo translate into a digital form. For example, optical scanners digitize images by translating them into bit maps. It is also possible to digitize sound, video, and any type of movement. In all these cases, digitization is performed by sampling at discrete intervals. To digitize sound, for example, a device measures a sound wave's amplitude many times per second. These numeric values can then be recorded digitally.

bus n. A set of hardware lines (conductors) used for data transfer among the components of a computer system. A bus is essentially a shared highway that connects different parts of the system—including the processor, disk-drive controller, memory, and input/output ports—and enables them to transfer information. The bus consists of specialized groups of lines that carry different types of information. One group of lines carries data; another carries memory addresses (locations) where data items are to be found; yet another carries control signals. Buses are characterized by the number of bits they can transfer at a single time, equivalent to the number of wires within the bus. A computer with a 32-bit address bus and a 16-bit data bus, for example, can transfer 16 bits of data at a time from any of 232 memory locations. Most PCs contain one or more expansion slots into which additional boards can be plugged to connect them to the bus.

from the American Heritage Dictionary: it is "The main board of a computer, usually containing the circuitry for the central processing unit, keyboard, and monitor and often having slots for accepting additional circuitry."

Hi,\n\nIt stands for metal oxide semiconductor field effect transistors. In the pass, people use metal material (aluminum) as the gate and oxide as insulator. That's why it is called metal-oxide. And it uses semiconductor to achieve the on/off function or amplification operations through the electric field. That's use it is called field effect transistors. Transistors means "trans-resistors (means changing resistance)". \n\n\nIn summary, by applying voltage to the metal gate, through the oxide insulator, we can achieve "trans-resistor" effect in the semiconductor due to the electric field. That's why we have MOSFET - Metal-oxide-semiconductor field effect transistors.\n\nBut today, people are using poly-silicon as the gate material. But we continue to name it as MOSFET.\n\nLet us know if you have more questions.\n\nKodKodKod Learning Consulting\nhttp://www.kodkodkod.com

City and Guilds in electronic engineering, at a guess?\n\nOnly a guess mind - why dont you call the local company that installs them, or even ask your local fire brigade?\n\nHope that helps.

A residual current device (RCD), or residual current circuit breaker (RCCB), is an electrical wiring device that disconnects a circuit whenever it detects that the flow of current is not balanced between the phase ("hot") conductor and the neutral conductor. The presumption is that such an imbalance may represent current leakage through the body of a person who is grounded and accidentally touching the energized part of the circuit. A shock, possibly lethal, is likely to result from these conditions; RCDs are designed to disconnect quickly enough to prevent such shocks.

Its an art to remove it. What it is, is a PCB radiating EMI above certain levels (depends on what you are testing for, FCC class A, B, etc...). Filtering power inputs is a good start, also any other data lines entering or leaving can act as an antenna and radiate EMI. Filtering is also recommended.
