Question 1

Which type of connector was developed to simplify the connection of peripheral devices to a PC?
A)DVI
B)Universal Serial Bus
C)RJ-45
D)HDMI

Accepted Answer

The Universal Serial Bus (USB) was developed to simplify the connection of peripheral devices to a PC. It allows for easy plug-and-play functionality and has become the standard for connecting devices such as printers, cameras, and external hard drives.

Question 2

Which type of computer monitor utilizes two sheets of polarizing material to encompass a liquid crystal solution?
A)LED panel
B)CRT monitor
C)CRT panel
D)LCD panel

Accepted Answer

LCD panels utilize two sheets of polarizing material to encompass a liquid crystal solution, which allows for the display of images. LED panels also use liquid crystals, but they are backlit using LED lights rather than traditional CCFL bulbs. CRT monitors and panels use cathode ray tubes to display images.

Question 3

Which component is found in modern video adapters to allow the adapter to store images for the display?
A)RAM
B)ROM
C)CMOS
D)BIOS

Accepted Answer

RAM (Random Access Memory) is used as a temporary storage location for images in video adapters. This allows the adapter to quickly access and display the images on the screen. ROM (Read Only Memory), CMOS (Complementary Metal-Oxide-Semiconductor), and BIOS (Basic Input/Output System) are not typically used for storing images in modern video adapters.

Question 4

Which of the following is NOT found on a system board?
A)AC power connectors
B)processor socket
C)SATA connectors
D)DIMM sockets

Accepted Answer

AC power connectors are typically found on the power supply unit (PSU), not on the system board. The other options listed (processor socket, SATA connectors, DIMM sockets) are all commonly found on a system board.

Question 5

Which of these PC components is NOT considered a peripheral device?
A)pointing device
B)sound adapter
C)keyboard
D)printer

Accepted Answer

Peripherals are devices that connect to the computer to provide additional functionality, such as input or output capabilities. Pointing devices (such as a mouse or trackpad), keyboards, and printers are all peripherals. However, a sound adapter is an internal component of the computer that is not considered a peripheral device.

Question 6

Which of the following video cable connectors has 29 pins and can be directly converted to HDMI format?
A)VGA
B)DVI
C)USB
D)LED

Accepted Answer

The DVI cable connector has 29 pins and can be directly converted to HDMI format with a simple adapter, making it the best choice. VGA and USB cables do not have enough pins, and LED is not a video cable connector.

Question 7

Before you begin to clean the inside of a PC case, it is important to take precaution and complete what critical first step?
A)discharge all static electricity
B)power down the PC
C)ground the PC case
D)disconnect the power cord

Accepted Answer

Disconnecting the power cord is the critical first step to ensure that there is no electrical power running to the PC, which minimizes the risk of electric shock and damage to the PC components during cleaning.

Question 8

The system board contains the logic circuitry that performs the instructions of a computer's applications.

Accepted Answer

The system board, or motherboard, houses the CPU, which performs the instructions of a computer's applications, but the board itself does not execute instructions.

Question 9

Which controller type transfers data bits over multiple data lines in parallel?
A)USB controller
B)SAS controller
C)SATA controller
D)PATA controller

Accepted Answer

PATA (Parallel ATA) controller transfers data in parallel over multiple data lines. SATA (Serial ATA) and SAS (Serial Attached SCSI) controllers transfer data over a single data line in series. USB (Universal Serial Bus) controllers also transfer data over a single data line in series, although they can use multiple data lines for faster transfer speeds.

Question 10

Which of the following is referred to as the guest operating system when using virtualization software?
A)OS running on the physical machine
B)OS that is available through multiboot installations
C)OS running on the virtual machine
D)OS that is accessed remotely

Accepted Answer

The guest operating system is the operating system that runs on the virtual machine, which is created by the virtualization software on top of the physical machine's operating system. The physical machine's operating system is the host operating system. Option A refers to the host operating system and options B and D do not accurately describe the concept of a guest operating system in the context of virtualization.

Question 11

Which of the following terms refers to the size and configuration of a computer case?
A)physical arrangement
B)case factor
C)case specifications
D)form factor

Accepted Answer

Form factor refers specifically to the size and configuration of a computer case, so this is the correct answer. The other options may be related to computer hardware, but they don't address the specific question of case size and configuration.

Question 12

Which networking cable connector, compatible with eight-wire twisted pair cable, is the standard Ethernet connector?
A)RJ-45
B)USB
C)RJ-11
D)DVI

Accepted Answer

The standard Ethernet connector is the RJ-45, which is compatible with eight-wire twisted pair cable. USB, RJ-11, and DVI connectors are not Ethernet connectors.

Question 13

Which is a common storage device that uses lasers to produce light to store data on devices such as DVDs and Blu-ray disks?
A)tape drive
B)flash drive
C)magnetic drive
D)optical drive

Accepted Answer

Optical drives use lasers to produce light to store data on devices such as DVDs and Blu-ray disks. Tape drives, flash drives, and magnetic drives do not use lasers to store data.

Question 14

A PC power supply adjusts the 110-volt AC, found in your office or home, to the various alternating current levels required by a PC.

Accepted Answer

A PC power supply adjusts the AC voltage to DC voltage levels required by a PC, not the various alternating current levels.

Question 15

Which of the following devices would NOT be considered a communication device and support the transmission of data between devices?
A)modulator-demodulator
B)NIC
C)Ethernet
D)wireless adapter

Accepted Answer

Ethernet is a networking technology and protocol that is used to connect devices together and transmit data. While it is involved in communication between devices, it is not itself a communication device but rather a means of facilitating communication. The other options (modulator-demodulator, NIC, and wireless adapter) are all directly involved in the transmission and reception of data between devices and can be considered communication devices.

Question 16

Which type of printer uses the same kind of technology found in copy machines?
A)dot matrix
B)ink-jet
C)laser jet
D)laser

Accepted Answer

Laser printers use the same technology as copy machines, where a laser beam is used to transfer toner onto the paper. This produces high-quality text and graphics, making it a popular choice for office and home use.

Question 17

Most types of random access memory are considered volatile and do not require a constant flow of electricity to preserve its contents.

Accepted Answer

Most types of random access memory (RAM) are considered volatile, which means they do require a constant flow of electricity to preserve their contents. When the power is turned off, the data stored in RAM is lost.

Question 18

The use of software that enables the physical hardware of a PC to be simulated is referred to as virtualization.

Accepted Answer

Virtualization is the use of software to create a virtual environment that mimics the physical hardware of a computer.

Question 19

Which computer component can be described as a printed circuit that can be inserted into a system board to add additional functionality to a PC?
A)power supply
B)expansion card
C)CPU socket
D)com port

Accepted Answer

An expansion card is a printed circuit that can be inserted into a system board and adds additional functionality to a PC. The other options (power supply, CPU socket, and com port) are not designed to add additional functionality through insertion into a system board.

Question 20

ESD is the discharge of static electricity between two conductors of different potential.

Accepted Answer

ESD stands for Electrostatic Discharge, which occurs when there is a sudden flow of electricity between two conductors of different potential, such as when you touch a metal object after walking on a carpet.
