MODULE 1 Flashcards
(26 cards)
It is the buildup of an electric
charge resting on a surface
Electro Static Discharge (ESD)
The amount of volts to fry and damage a computer component
less than 30 volts
Humans can’t feel static shock until it is ________________ volts strong
3000
If the discharge causes pain, the charge was probably above ________ volts
10,000
It is an area that helps to protect employees or workers from accident, computer hazard, risk, and injury while at work
Occupational Safety and Health (OSH)
It is used to stand on or to place hardware on top to prevent static electricity from building up, thereby protecting the equipment from ESD damage
Anti-Electrostatic Mat
It is the collection, transport, processing or disposal, managing and monitoring of waste materials
Waste Management
This tool is used to safely ground a person working on very sensitive electronic equipment, to prevent the buildup of static electricity on their body, which can result in ESD
Anti-Electrostatic Wrist Strap
A fire extinguisher class that is effective for fires burning paper, wood, plastics, and cardboard materials
Class A
A fire extinguisher class that is effective for fires burning gasoline, kerosene, or organic solvents
Class B
A fire extinguisher class that is effective for fires burning electrical equipment
Class C
A fire extinguisher class that is effective for fires burning combustible metals, such as magnesium and titanium
Class D
An electrical apparatus that provides emergency power to a computer system when the input power source, typically main power, fails
UNINTERRUPTIBLE POWER SUPPLY (UPS)
An electrical apparatus that provides a backup battery to supply power when the incoming voltage drop below the normal level
STANDBY POWER SUPPLY (SPS)
4 power protection devices
1) Surge Suppressor
2) UPS
3) SPS
4) AVR
2 Anti-ESD Tools
1) Anti-Electrostatic Wrist Strap
2) Anti-Electrostatic Mat
The memory aid use to remember the basic rules of fire extinguisher operation
P - Pull the Pin
A - Aim at the base of fire, not at the flames
S - Squeeze the Lever
S - Sweep the Nozzle from Side to Side
If the environment temperature is too high, equipment can suffer from?
overheat
If the humidity level is too low, ____________________________
the chance of ESD increases
If the humidity level is too high, equipment can suffer from?
moisture damage
It is the inadequate or improper and unsteady supply of voltage and current
Power Fluctuation
Complete loss of AC power. A blown
fuse, damaged transformer, or downed power line can cause?
Blackout
Reduced voltage level of AC power
that lasts for a period of time. This occur when the power line voltage drops below 80 percent of the normal voltage level. Overloading
electrical circuits can cause?
Brownout
Sudden increase in voltage that lasts for a short period and exceeds 100 percent of the normal voltage on a line.
Spike
