| Chapter 4 Vocab. Continued Hard Drive Standby Time- The amount of time before a hard drive will shutdown to conserve energy. Intelligent UPS- A UPS connected to a computer by way of a serial cable so that software on the computer can monitor and control the UPS. Line Conditioner. A device that regulatse or conditions power providing continuous voltage during brownouts and spikes. Line-Ineractive UPS- A variation of standby UPS that shortens switching time by slawys keeping the invertor that converts AC to DC working so that there is no chrage-up time for the invertor. Low profile Case- See compact case. LPX- Low Profile Extended- A from factor in which Expansion Cards are mounted on a riser card that plugs into a motherboard. The expansion cards in LPX systems are mounter parellel to the motherboard rather than perpendicular to it as in AT and ATX systems. Micro ATX- A recent version of the ATX form factor. Micro ATX addresses some new technology that have been developed since the orginal introduction of ATX. Mini ATX- A smaller version of the ATX board that can be used with regular ATX cases and power supplies. Mini LPX- A smaller version of the LPX motherboard. Multimeter- A deivice used to measure the various compnents of an electrical cicuit. The most commen measurements are voltage, current and resistance. NLX- New Low Profile Extended- A low-end form factor that is similiar to LPX but provides greater support for current and emerging tchnologies. NLX was designed got flexibility and effiency of space. Ohms- The statdard unit of measure ment for resistance. Passive Backplane- A type of Backplane system in which the backplane contains no circuitry at all. Passive backplanes locate all circuitry on a mothercard plugged into a back plane. Power Conditioner- A line conditioner that regulates, or conditions, oiwer providing continous voltage during brownouts. Rectifier- An Electrical device that converts AC to DC. Resistance- The degree to which opposes or resists the flow of electricity. As the electrical resistance increase, the current decreases. Resistor- An electronic device that restists or opposes the flow of electricty. can be used to reduce the amount of electricity being supplied to an electronic component. Riser Card- A card that plugs into a motherboard and allows for expansion cards to be mounted parellel to the motherboard. Sleep mode- A mode used in many "Green" System that allows them to be configured through CMOS to suspend the monitor or even the drive, if the keyboard and/or the CPU have been inactive for a set of number of minutes. Slimecase- See Compact Case Soft Power- See Soft Switch Soft Switch- A feature on an ATC system that allows an OS to power down the system and allows for activity such as a keystroke or network activity to power up the system. Spikes- Temporary surges in voltage, which can damage electrical components. Standby Time- The time before a "Green" system will reduce 92% of its activity. Static Electricity- See ESD Page 1 Page 2 Page 3 Home |
