|
Accelerated Graphics Port (AGP)
|
A 32/64-bit expansion slot designed by Intel specifically for video that runs at 66 MHz and yields a throughput of at least 254 MBps. Later versions (2X, 4X, *x) give substantially higher throughput.
|
|
|
Anti-Static Bag
|
A silver of pink bag that is designed to protect sensitive components by ensuring that any static charge collects on the outside of the bag rather than the components inside.
|
|
|
Anti-Static Strap
|
A specially designed device to bleed electrical charges away safely. It uses a 1-megohmresitor to bleed the charge away slowly and protect computer hardware.
|
|
|
BIOS (Basic Input/Output Services)
|
Classically, the software routines burned onto the system ROM of a PC. More commonly seen as any software that directly controls a particular piece of hardware. A set of programs encoded in Read-Only Memory (ROM) on computers. These programs handle startup operations and low-level control of hardware such as disk drives, the keyboard, and monitor.
|
|
|
Chipset
|
Electronic chips that handle all of the low-level functions of a PC, which in the original PC were handled by close to 30 different chips. The usually consist of one, two, or three seperate chips embedded into a motherboarde to handle all of these functions.
|
|
|
Class C Extinguisher
|
The class of fire suppression designed for electrical fires.
|
|
|
CPU (Central Processing Unit)
|
The "Brain" of the computer. The microprocessor that handles the primary calculations for the computer. CPUs
|
|
|
RT (Cathode Ray Tube)
|
The tube of a monitor in which rays of electrons are beamed onto a phosphorescent screen to prodece images. Also a shorthand way to describe a monitor that uses CRT rather than LCD technology.
|
|
|
Double Data-Rate SDRAM
|
A 184-pin high speed RAM that handles two signals per clock cycle. Can be installed singling or in pairs.
|
|
|
ESD (Electrostatic Discharge)
|
The movement of electrons from one body to another. ESD is a real menace to PCs as it can cause permanent damage to semiconductors.
|
|
|
Firmware
|
Software that has been written onto read-only memory (ROM). It is a combination of software and hardware. ROMs, PROMS and EPROMs that have data or programs recorded on them are considered this.
|
|
|
High-Voltage Probe
|
A tool with a very large needle, a gauge that indicates volts, and a wire with an alligator clip used to discharge electricity from electronic devices.
|
|
|
ISA (Industry Standard Architecture)
|
The type of expansion bus found in the original IBM PC for the slots on the motherboard that allowed additional hardware to be connected to the compter's motherboard. An 8-bit, 8.33 MHz expansion bus was designed by IBM for its AT computer and released to the public domain. An improved 16-bit bus was also released to the public domain.
|
|
|
Lithium-Ion battery
|
The most common type of battery used in a laptop. They are not considered hazardous waste so there are no regulations on recycling them, however, they should still be recylced.
|
|
|
Material Safety Data Sheet (MSDS)
|
A document that contains safety information about a given product. Information provided includes safe handling procedures, also what to do in case of an accident or spill, and how to properly dispose of the product.
|
|
|
Motherboard
|
The primary circuit board that holds all of the core components of the computer
|
|
|
MultiMeter
|
An electronic measuring instrument that combines several functions in one unit. The most basic instruments include an ammeter, voltmeter, and ohmeter. Analog mulitmeters are somtimes referred to as "vot-ohm-meters", abbreviated as VOM.
|
|
|
OSHA
|
The Federal agency in charge of ensuring that employers have a safe work environment.
|
|
|
Peripheral Component Interconnect
|
Design architecture for the sockets on the computer motherboard that enable system components to be added to the computer. It is a "local bus" standard, meaning that devices added to a computer through this port will use the processor at the motherboard's full speed (up to 33 MHz), rather than at the slower 8 MHz speed of the regular bus. In addition to moving data at a faster rate, it moves data 32 or 64 bits at a time, rather than the 8 or 16 bits that the older ISA buses supported.
|
|
|
PCI-e
|
Current generation of expansion cards, this has a serial bus with a rated bi-directional throughput of 250MB/s per lane, with up to 3 lanes. Meant to replace the PCI
|
|
|
Plug and Play
|
Also called PnP, a combination of smart PCs, smart devices, and smart operating systems that automatically configure all the necessary system resources and ports when you install a new peripheral device.
|
|
|
Amperes
|
The measurement of the amount of electricity flowing down a wire.
|
|
|
Rambus DRAM
|
A patented RAM technology that uses accelerated clocks to provide very high-speed memory. Requires the use of a Continuity RIMM to fill unused memory slots.
|
|
|
Torx Driver
|
A six sided, star shaped "screwdriver" used by some manufacturers. A phillips will not work in the type of screw.
|
|
|
Volts
|
The measurement of the "pressure" a current places on a wire.
