Q

Which of the following is used to connect to a wireless access point?

A. NIC

B. SSD

C. GPU

D. USB

A

A. NIC (Network Interface Card)

A NIC (Network Interface Card) is a hardware component that allows a device to connect to a network, including wireless networks. In the context of wireless networking, a wireless NIC, also known as a wireless adapter or Wi-Fi card, is used to connect a device (such as a computer or laptop) to a wireless access point.

17
Q

Which of the following characteristics describes MOST versions of RAM?

A. Cached

B. Read-only

C. Volatile

D. Programmable

A

C. Volatile

The characteristic that describes most versions of RAM (Random Access Memory) is volatility. RAM is volatile memory, meaning that it requires power to maintain stored data. When the computer is powered off, the data stored in RAM is lost. This volatile nature allows RAM to quickly read and write data but requires constant power to retain that data. As a result, RAM is primarily used for temporary storage of data and instructions that the CPU (Central Processing Unit) needs to access quickly during program execution.

18
Q

A user’s mouse appears to be jumping around the screen. Which of the following will MOST likely to fix the issue?

A. Update the drivers.

B. Clean the mouse.

C. Use a different USB port.

D. Restart the computer.

A

B. Clean the mouse.

If a user’s mouse appears to be jumping around the screen, the most likely solution to fix the issue is to clean the mouse. Dust, dirt, or debris on the mouse’s sensor or tracking surface can interfere with its ability to accurately track movement, causing erratic behavior such as cursor jumping. Cleaning the mouse’s sensor and tracking surface using compressed air and a soft cloth can often resolve this issue and restore normal mouse operation.

19
Q

When editing a document, which of the following describes where the changes are located before they are saved to permanent storage?

A. SSD

B. CPU

C. RAM

D. GPU

A

C. RAM

When editing a document, the changes are located in RAM (Random Access Memory) before they are saved to permanent storage. RAM is a type of volatile memory that provides temporary storage for data and instructions that are actively being used or processed by the computer’s CPU (Central Processing Unit). When you open a document for editing, the contents of the document are loaded from permanent storage (such as an SSD or HDD) into RAM, where they can be accessed and modified quickly by the CPU. Any changes made to the document are temporarily stored in RAM until they are saved back to permanent storage.

20
Q

Data contained on which of the following would have the HIGHEST expectation of privacy?

A. Mobile

B. Laptop

C. Cloud

D. Workstation

A

B. Laptop

Data contained on a laptop may have the highest expectation of privacy. Laptops are often carried by individuals and used in various locations, which means that users generally have more control over their physical security compared to workstations left unattended in an office or home environment. Users are more likely to always keep laptops with them, reducing the risk of unauthorized access to the data stored on them. Additionally, laptops may have security measures such as passwords, encryption, and biometric authentication to protect the privacy of the data stored on them. Therefore, data contained on a laptop typically has a higher expectation of privacy compared to other devices like workstations, mobile devices, or cloud storage.

21
Q

Which of the following components MOST likely will provide performance improvement by using an add-on card compared to the on-board component?

a. GPU

b. USB

c. Wi-Fi

d. CPU

A

A. GPU

A Graphics Processing Unit (GPU) is most likely to provide a performance improvement by using an add-on card compared to the on-board component. Dedicated GPU add-on cards often offer higher processing power, more memory, and advanced graphics capabilities compared to integrated GPUs found on the motherboard. This can result in improved graphics performance, better gaming experiences, and faster rendering of graphical content.

22
Q

A scanner is connected to a workstation that is being used to convert images and print out different types of images. Which part of this process would be considered the input device?

A. Scanner

B. Laptop

C. Printer

A

A. Scanner

An input device is any hardware component that allows users to input data into a computer system for processing. It takes external data and converts it into a digital format that the computer can understand and process.

In the scenario described, the scanner is responsible for capturing images (data) from physical documents or images and converting them into digital format for the workstation to process.

The laptop is the computing device where the processing takes place, and the printer is the output device that produces the final result.

23
Q

What piece of hardware is used to compute and render images accurate to physical dimensions/effects.

A. CPU

B. GPU

C, PSU

A

B.GPU

Render Images

25
Q

A computer technician is assigned a ticket to install a laptop for a new employee. Due to the arrangement of the workspace, the employee requests that the laptop be installed with the cover closed. Which of the following would be required to satisfy this request? (Choose two.)

A. Printer

B. Mouse

C. Webcam

D. External Hard Drive

E. Speakers

F. Display

A

B. Mouse & F. Display

Mouse: Without the laptop cover open, the built-in touchpad would not be accessible, so an external mouse would be needed for navigation.

Display: With the laptop cover closed, the built-in monitor would be hidden. The user would need an external display to view the laptop’s output.

26
Q

Which of the following storage types is MOST vulnerable to magnetic damage?

A. Flash
B. SSD
C. Optical
D. HDD

A

D. HDD (Hard Disk Drive)

HDD: they store data using magnetic storage. They contain spinning disks coated with magnetic material, and data is written and read using a magnetic head. Since HDDs rely on magnetic fields to read and write data, they are the most vulnerable to magnetic damage. Exposure to strong magnetic fields can corrupt or erase data stored on HDDs.

27
Q

Which of the following is MOST likely to be used to store or transfer data?

a. DVD

b. Floppy disk

c. Backup tape

d. USB

A

D. USB

USB (Universal Serial Bus) is the most common and versatile method used for storing and transferring data in modern computing environments. USB flash drives, also known as thumb drives or USB sticks, are portable storage devices that use USB interfaces to connect to computers and other devices. They are widely used due to their convenience, portability, and large storage capacities.
