Correct
Incorrect
Hint

2. Question
1 pointsWhat is a characteristic of thin clients?
Correct
Incorrect
Hint
Explanation:
A thin client device is typically a type of low-end computer that does not perform any processing or data storage locally. A thin client relies on a network connection to access any resources required to perform computing tasks and operate software. -
Question 3 of 15
3. Question
1 pointsWhich adapter card in a PC would provide data fault tolerance?
Correct
Incorrect
Hint
Explanation:
A RAID controller controls the expansion of internal and external drives as well as providing fault tolerance for storage devices. The I/O card allows additional I/O ports to be added to a computer. A capture card imports video information into a computer and records it to the storage device. SD storage cards are a form of removable storage used widely in portable devices. -

4. Question
1 pointsWhat unit is used to measure the amount of resistance to the flow of current in a circuit?
Correct
Incorrect
Hint
Explanation:
The resistance of a circuit to the flow of current is measured in ohms (O). Amps (A) measure the amount of electrons moving through the circuit. Watts (W) measure the work required to move electrons through the circuit. Volts (V) measure the work required to move a charge from one location to another. -
Question 5 of 15
5. Question
2 pointsWhich two software interfaces allow adjustment of the CPU voltage? (Choose two.)
Correct
Incorrect
Hint
Explanation:
When the CPU is being replaced or upgraded, the correct voltage must be matched. The CPU voltage can be set in the BIOS or UEFI software. -
Question 6 of 15
6. Question
3 pointsWhich three devices are considered output devices? (Choose three.)
Correct
Incorrect
Hint
Explanation:
Headphones, monitors, printers, speakers,scanners, fax machines, and projectors are all considered output devices. Fingerprint scanners, keyboards, and mice are all considered input devices. -
Question 7 of 15
7. Question
1 pointsWhat type of memory is integrated directly into the CPU chip to provide fast access to data?
Correct
Incorrect
Hint
Explanation:
Memory is the temporary storage area of data that is accessed by the CPU. The fastest memory is known as static RAM (SRAM). Because SRAM is so fast, it is typically used as L1 cache. L1 cache is internal cache and is integrated into the CPU. -
Question 8 of 15
8. Question
2 pointsWhich two pieces of information are needed before selecting a power supply? (Choose two.)
Correct
Incorrect
Hint
Explanation:
When building a computer, select a power supply with sufficient wattage to power all the components. Each component inside the computer uses a certain amount of power. Obtain the wattage information for the components from the manufacturer documentation. When deciding on a power supply, make sure to choose a power supply that has more than enough power for the current components.
The shape of the computer case is usually determined by the motherboard, power supply, and other internal components. -
Question 9 of 15
9. Question
4 pointsWhen a computer is being built, which three components must have the same form factor? (Choose three.)
Correct
Incorrect
Hint
Explanation:
The form factor pertains to the shape of the mother board and case. Additionally the case must accommodate the shape of the power supply. -
Question 10 of 15
10. Question
1 pointsFill in the blank.
- A user has a new computer with only a USB port. The user will need a USB to Ethernet (adapter, adaptor, converter, ADAPTER) to connect to the office wired LAN.
