Electromagnetic Interference (EMI)

Back 9

The intrusion of outside electromagnetic signals in a transmission media, such as copper cabling.

Front 10

Electrostatic Discharge (ESD)

Back 10

The sudden flow of electricity between two electrically charged objects caused by contact, an electrical short, or dielectric breakdown. A buildup of static electricity can be caused by tribocharging or by electrostatic induction.

Front 11

Radio Frequency Interference (RFI)

Back 11

The radio frequency spectrum, is a disturbance generated by an external source that affects an electrical circuit by electromagnetic induction, electrostatic coupling, or conduction.

Front 12

Blackout

Back 12

Complete loss of AC power. A blown fuse, damaged transformer, or downed power line can cause a blackout.

Front 13

Brownout

Back 13

Reduced voltage level of AC power that lasts for a period of time.

Front 14

Noise

Back 14

Interference from generators and lightning. Noise results in poor quality power, which can cause errors in a computer system.

Front 15

Spike

Back 15

Sudden increase in voltage that lasts for a short period and exceeds 100 percent of the normal voltage on a line.

Front 16

Surge

Back 16

Dramatic increase in voltage above the normal flow of electrical current. A power surge lasts for a few nanoseconds, or one-billionth of a second.

Front 17

Standby Power Supply (SPS)

Back 17

Helps protect against potential electrical power problems by providing a backup battery to supply power when the incoming voltage drops below the normal level.

Front 18

Uninterruptible power supply (UPS)

Back 18

Helps protect against potential electrical power problems by supplying a consistent level of electrical power to a computer or other device.

Front 19

Surge Suppressor

Back 19

Helps protect against damage from surges and spikes. A surge suppressor diverts extra electrical voltage that is on the line to the ground.

Front 20

Material Safety and Data Sheet

Back 20

A document that contains information on the potential health effects of exposure to chemicals, or other potentially dangerous substances, and on safe working procedures when handling chemical products.

Front 21

CHKDSK

Back 21

Checks the integrity of files and folders on a hard drive by scanning the file system. These tools might also check the disk surface for physical errors. (Scandisk)

Front 22

Defrag

Back 22

Reduce the fragmentation of (a file) by concatenating parts stored in separate locations on a disk.

Front 23

Disk Cleanup

Back 23

A computer maintenance utility included in Microsoft Windows designed to free up disk space on a computer's hard drive.

Front 24

FDISK

Back 24

A command-line utility used on PCs to partition hard drive space, and other storage media space, into logical drives or partitions and assigns drive letters such as C, D, E, etc.

Front 25

Scandisk

Back 25

Checks the integrity of files and folders on a hard drive by scanning the file system. These tools might also check the disk surface for physical errors. (CHKDSK)

Front 26

Disk Management

Back 26

Clears space on a hard drive by searching for files that can be safely deleted.

Front 27

Anti-virus Applications

Back 27

Computer software used to prevent, detect and remove malicious software. Antivirus software was originally developed to detect and remove computer viruses, hence the name.

Front 28

Spyware

Back 28

Software that enables a user to obtain covert information about another's computer activities by transmitting data covertly from their hard drive.

Front 29

Self Grounding

Back 29

The action or grounding yourself or making a ground outlet if you don't have one.

Front 30

Cable Tie

Back 30

A type of fastener, for holding items together, primarily electric cables or wires.

Front 31

Flat-head Screwdriver

Back 31

A screwdriver with a "Flat Head".

Front 32

Toner Probe

Back 32

The toner part is connected to a cable at one end using specific adapters. The toner generates a tone that travels the length of the cable. The probe part traces the cable. When the probe is in near proximity to the cable to which the toner is attached, the tone can be heard through a speaker in the probe.

Front 33

Digital Multimeter

Back 33

A test tool used to measure two or more electrical values—principally voltage (volts), current (amps) and resistance (ohms).

Front 34
