Answering secret questions with answers provided during account setup

86
Q

Computer safety involves:

A

keeping computers safe from failure and keeping technicians safe while working in a dangerous environment.

87
Q

The concepts in the Computer safety section are:

A

Preventing electrostatic discharge

Working with electricity safely

Handling toxic waste

Protecting personal and physical safety

88
Q

Construction codes require:

A

that every building with electrical service must be grounded

89
Q

Grounding an electrical system means:

A

making a direct connection from the building’s electrical service to the earth so that dangerous voltage from line surges and lightning strikes will find its way into the earth instead of injuring people, damaging equipment, or causing a fire

90
Q

Every grounded outlet in a building has:

A

a direct connection to a metal grounding electrode that goes several feet into the earth

91
Q

Grounded outlets have:

A

three prongs in almost all world areas

92
Q

When should you use a grounded to ungrounded adapter?

A

When a grounded outlet is not available

93
Q

A grounded to ungrounded adapter can be used for:

A

temporary setups if the loop on the adapter can be connected to a working ground

94
Q

In the US, what electrical outlet has been required by code since 1962?

A

grounded 120V AC electrical outlets

95
Q

Electrostatic discharge (ESD) is:

A

the silent enemy of computer equipment

96
Q

Electrostatic discharge (ESD) may be:

A

too low for humans to detect but still strong enough to damage electronic components

97
Q

Equipment can be damaged by:

A

Electrostatic discharge (ESD) of 700V or higher

98
Q

A humidity decrease:

A

the voltage released during Electrostatic discharge (ESD) climbs

99
Q

Without Electrostatic discharge (ESD) protection:

A

static electricity will seek to discharge to anything else that has a different electric potential-especially metallic items like circuit boards

100
Q

Casually picking up an expensive video card can:

A

possibly damage it and cause a complete failure or could cause intermittent issues that would be difficult to troubleshoot

101
Q

There are four keys to protection from Electrostatic discharge (ESD):

A

Antistatic bags

ESD straps

ESD mats

Self-grounding

102
Q

When removing, a component from a computer, immediately:

A

place it in an antistatic bag and put it off to the side

103
Q

Removed parts should never be:

A

lying around outside an antistatic bag

104
Q

Normal bubble wrap bags do not:

A

constitute antistatic protection, so make sure to use proper antistatic bags

105
Q

After an item is placed in an antistatic bag:

A

place it in a protective box to avoid physical impact damge

106
Q

An Electrostatic discharge (ESD) strap is designed to:

A

equalize the electric potential of the user and the device the strap is clipped to, such as the interior of a computer

107
Q

By equalizing the electric potential, Electrostatic discharge (ESD) is prevented because the:

A

ESD is the movement of electricity between two objects with different electric potential

108
Q

An Electrostatic discharge (ESD) strap has two pieces:

A

An elastic or hook-and-loop strap with a built-in metal snap backed by a metal plate

A coiled flexible cable with a matching snap at one end and an alligator clip at the other end. The snap contains a 1 megohm resistor, which can help prevent injury in case of electrical discharge

109
Q

To properly use an ESD strap, follow these steps:

A
  1. Place the elastic or hook-and-loop strap around one wrist with the flat metal plate against the skin
  2. Adjust the strap until the metal plate stays in place as you move your wrist
  3. Snap the cable to the strap around your write
  4. Open the alligator cable and clamp it to unpainted metal on the object you are servicing
110
Q

The strap around your wrist with the metal place, snap, and cable equalizes:

A

electrical potential between you and the object you are servicing to prevent ESD

111
Q

An Electrostatic discharge (ESD) mat can be connected to a device being repaired using one of the following methods:

A

A cable with an alligator clip

A cable with a loop designed to be held in place by a case screw but with the cable snapped to the mat rather than to your wrist

112
Q

Self-grounding involves:

A

touching a nearby metal component before touching a device being serviced. Before opening a computer, you can self-ground by touching an unpainted portion of a chair before picking a component up or opening the device

113
Q

Before opening a computer, you can self-ground by:

A

touching an unpainted portion of the case with both hands before installing or uninstalling a component

114
Q

You should self-ground:

A

every time before touching a component if no other antistatic options are available

115
Q

When working with electronics, consider these precautions:

A

When handling components or cards, hold them by the edge or bracket

When handling components, stay stationary

Remove jewelry and wear protective clothing

If possible, work in a non-carpeted area

Avoid using AC-powered tools near a computer

116
Q

There are five types of computer-related toxic waste that the exam addresses for safe handling:

A

Batteries

Toner

CRT displays

Cell phones

Tablets
