ITE ESSENTIALS CHAPTERS 1-4 EXAM QUESTIONS WITH CORRECT ANSWERS LATEST UPDATE 2026
Form Factor - Answers the size, shape and physical layout of computer components such as case,
motherboard, and power supplies
volts - Answers the measure of the work that is required to move a charge from one location to
another
ohms - Answers the measure of resistance to the flow of current in a circuit
amps - Answers the measure of the number of electrons moving through a circuit per second
watts - Answers the measure of the work per second of electrical current
cpu - Answers the brain of the computer
ram - Answers the main temporary working storage location for data and programs (Random Access
Memory)
rom - Answers memory location that stores basic operational instructions used by the CPU for
booting the computer (Read Only Memory)
RAID - Answers a redundant array of disk drives that provides redundancy and fault tolerance
solid state drives - Answers storage devices that are replacing magnetic disk drives for permanent
data storage
hard disk drives - Answers magnetic disk drives that are used for permanent data storage
thin client - Answers computers that rely on a central server for all, or most, data storage and
processing resources
motherboard - Answers the main circuit board inside the computer to which all computer
components connect
chipset - Answers integrated circuits on the motherboard that control system hardware interaction
with the CPU and motherboard
ESD - Answers stands for electrostatic discharge, a sudden discharge of built-up static electricity
between two different surfaces with different charge levels
EMI - Answers stands for electromagnetic interference, a disturbance affecting transmission media
that use electrical signals. The disturbance is caused by electromagnetic field variations
brownout - Answers a situation where voltage drops below 80 percent of the normal voltage over a
period of time
power surge - Answers a significant increase in voltage above the normal voltage of a power line over
a short period of time
UPS - Answers stands for uninterruptible power supply, a supplemental power resource that helps
maintain the power requirements by providing a secondary, consistent level of electrical power to a
device
MSDS - Answers stands for material safety and data sheet, a fact sheet to provide information about
material identification, fire hazards, and first-aid requirements. It also provides protective measures
for the safe handling and storage of materials and spill, leak, and disposal procedures.
toner generator and probe - Answers a two-part tool that is typically used to identify an individual
wire in a circuit. The toner part is connected to a cable at one end and generates a tone that travels
inside the cable. The probe part traces the cable. When the probe is in close to the cable to which the
toner is attached, the tone can be heard in the probe.
history of repairs - Answers a detailed list of problems and repairs that is maintained by a technician
or by a support desk system. The list should include the date, problems identified, actions to correct
the problems, replacement parts, and customer information. The records would allow a technician to
determine what work has been performed in the past on a specific computer.
antistatic wrist strap - Answers a conductor that connects the wrist of a technician to the device that
the technician is working on. When static electricity (ESD) builds up in the body, the connection made
by the wrist strap to the device balances the electrical charge by channeling the electricity through
the wire that connects the strap.
antistatic mat - Answers a mat that is slightly conductive so as to help eliminate static electricity
(ESD). It does this by drawing static electricity away from a component and transferring it safely from
equipment to a grounding point.
power supply tester - Answers a device that can be used to check whether the power supply of a
device is working properly
cable tester - Answers a device that can be used to check the condition of a data cable, including
wiring shorts, faults, or wires that are connected to the wrong pins
