Mod 2 Unit 1

Front 1

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, 8X) give you substantially higher throughput.

Back 1

Accelerated Graphics Port (AGP)

Front 2

A silver or 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.

Back 2

Anti-static Bag

Front 3

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.

Back 3

Anti-static Strap

Front 4

Classically, the software routines burned onto the System ROM of 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. There programs handle startup operations and low-level control of hardware such as disk drives, the keyboard, and monitor.

Back 4

BIOS (Basic Input/Output Services)

Front 5

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. They usually consist of one, two, or three separate chips embedded into a motherboard to handle all of these functions.

Chipset

Front 6

The class of fire suppression designed for electrical fires.

Back 6

Class C Extinguisher

Front 7

The "brain" of the computer. The microprocessor that handles the primary calculations for the computer.

Back 7

CPU (Central Processing Unit)

Front 8

The tube of a monitor in which rays of electrons are beamed onto a phosphorescent screen to produce images. Also a shorthand way to describe a monitor that uses CRT rather than LCD technology.

Back 8

CRT (Cathode Ray Tube)

Front 9

A 184-pin high-speed RAM that handles two signals per clock cycle. Can be installed singling or in pairs.

Back 9

Double Data-Rate SDRAM

Front 10

The movement of electrons from one body to another. ESD is a real menace to PCs as it can cause permanent damage to semiconductors.

Back 10

ESD (Electrostatic Discharge)

Front 11

Software that has been written onto read-only (ROM). It is a combination of software and hardware. ROMs, PROMs, and EPROMs that have data or programs recorded on them are considered this.

Back 11

Firmware

Front 12

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.

Back 12

High-voltage Probe

Front 13

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 computer'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.

Back 13

ISA (Industry Standard Architecture)

Front 14

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 should still be recycled.

Back 14

Lithium-Ion Battery

Front 15

A document that contains safety information about a given product. Information provided includes safe handling procedures, what to do in case of an accident, and disposal information.

Back 15

Material Safety Data Sheet

Front 16

The primary circuit board that holds all of the core components of the computer.

Back 16

Motherboard

Front 17

An electronic measuring instrument that combines several functions in one unit. The most basic instruments include an ammeter, voltmeter, and ohmmeter. Analog multimeters are sometimes referred to as "volt-ohm-meters", abbreviated VOM.

Back 17

MultiMeter

Front 18

The Federal agency in charge of ensuring that employers have a safe work environment.

Back 18

OSHA

Front 19

Design architecture for the sockets on the computer motherboard that enable system components to be added to the computer. It is a 'local buss" 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.

Back 19

Peripheral Component Interconnect

Front 20

Current generation of expansion cards, this has serial bus with a rather bi- directional throughput of 250 MB/s per lane, with up to 3 lanes. Meant to replace the PCI.

Back 20

PCI-e

Front 21

Also called PnP, a combination of smart PCs, smart devices, and smart operating systems that automatically configure all the necessary system resources and port when you install a new peripheral device.

Back 21

Plug and Play

Front 22

The measurement of the amount of electricity flowing down a wire.

Back 22

Amperes

Front 23

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.

Back 23

Rambus DRAM

Front 24

A six-sided, star-shaped "screwdriver" used by some manufacturers. A Phillips will not work in this type of screw.

Back 24

Torx Driver

Front 25

The measurement of the "pressure" a current places on a wire.
