Which of the following is used to store the initial programming that is used to start the computer when it is first turned on?
- A.
RAM
- B.
Hard Disk
- C.
ROM
- D.
CD
Correct Answer
C. ROMExplanation
ROM stands for Read-Only Memory, which is a type of non-volatile memory that stores the initial programming or firmware of a computer. It contains the instructions necessary to boot up the computer when it is first turned on. Unlike RAM or Hard Disk, ROM retains its data even when the power is turned off, making it ideal for storing essential startup instructions that are required every time the computer is powered on. CDs, on the other hand, can also store data, but they are not typically used to store the initial programming of a computer.Rate this question:

Which of the following is true of Read Only Memory (ROM)?
- A.
It is non-volatile
- B.
It temporarily stores programs and files while you are working on them
- C.
Its contents are lost when the power is turned off
- D.
It is used as removable storage
Correct Answer
A. It is non-volatileExplanation
ROM is a type of computer memory that is non-volatile, meaning that its contents are not lost when the power is turned off. Unlike temporary storage or removable storage, ROM is designed to permanently store data, instructions, and programs that are essential for the operation of a computer system. This makes ROM ideal for storing firmware and other critical information that needs to be retained even when the power is not available.Rate this question:

Booting a computer refers to what stage of the flow of information in a computer?
- A.
Startup of the computer
- B.
Starting an application program
- C.
Opening a file within an application program
- D.
Erasing unwanted files
Correct Answer
A. Startup of the computerExplanation
Booting a computer refers to the initial stage of the flow of information in a computer, where the system is powered on and the operating system is loaded into the computer's memory. This process includes the hardware initialization, self-tests, and loading of necessary software components to prepare the computer for use. Therefore, the correct answer is "Startup of the computer."Rate this question:

Which of the following is not a reason to share resources on a network?
- A.
To buy fewer printers
- B.
To allow each worker to function independently
- C.
To pay for one Internet connection for a group of computers
- D.
To transfer files and data easily between computers
Correct Answer
B. To allow each worker to function independentlyExplanation
Sharing resources on a network allows for efficient use of resources and cost savings. However, allowing each worker to function independently goes against the concept of resource sharing. When resources are shared, it promotes collaboration and teamwork by allowing multiple users to access and utilize the same resources, such as printers, internet connections, and file transfers. Allowing each worker to function independently would imply that they do not need to rely on shared resources, which contradicts the purpose of resource sharing on a network.Rate this question:

Which of the following is optical storage media?
- A.
DVD-R
- B.
Hard Disk
- C.
SD Card
- D.
Removable Disk
Correct Answer
A. DVD-RExplanation
DVD-R is considered optical storage media because it uses optical technology to read and write data. Optical storage media uses lasers to read and write data onto a disc, such as a DVD. In the case of a DVD-R, it can be written to once and then becomes a read-only disc. This is different from other options like a hard disk, SD card, or removable disk, which are all examples of magnetic or flash storage media, not optical.Rate this question:

Which of the following is no a common input device?
- A.
Keyboard
- B.
Microphone
- C.
Voice synthesizer
- D.
Mouse
Correct Answer
C. Voice synthesizerExplanation
A voice synthesizer is not a common input device because it is primarily used as an output device. It takes text or other input and converts it into spoken words or sounds. In contrast, a keyboard, microphone, and mouse are all commonly used input devices. A keyboard allows users to input text and commands, a microphone allows users to input audio, and a mouse allows users to input movement and commands through clicking and scrolling.Rate this question:

- D.
Cable, expansion card, port, expansion slot, motherboard
Correct Answer
A. Cable, port, expansion card, expansion slot, motherboardExplanation
The correct answer is cable, port, expansion card, expansion slot, motherboard. This is the correct order in which the items are connected from the peripheral device to the computer. The cable is used to physically connect the peripheral device to the computer. The port is the interface on the computer where the cable is plugged in. The expansion card is inserted into the expansion slot on the motherboard to add additional functionality. The expansion slot is a connector on the motherboard that allows for the installation of expansion cards. Finally, the motherboard is the main circuit board of the computer that connects all the components together.Rate this question:

- D.
Driver
Correct Answer
D. DriverExplanation
A driver is a program that works with an operating system to manage a device. It acts as a bridge between the device and the operating system, allowing them to communicate and work together effectively. The driver provides the necessary instructions and protocols for the device to function properly within the operating system environment. Without a driver, the device may not be recognized or utilized correctly by the operating system. Therefore, a driver is essential for the proper functioning and management of a device within an operating system.Rate this question:

Which of the following protects your computer from pulses of higher-than-normal electric voltage?
- A.
Circuit breaker
- B.
Surge suppressor
- C.
Plug strip
- D.
Grounded outlet
Correct Answer
B. Surge suppressorExplanation
A surge suppressor is designed to protect electronic devices, including computers, from sudden spikes in electric voltage. These spikes, also known as power surges, can occur due to lightning strikes, power outages, or electrical faults. Surge suppressors have built-in components that divert excess voltage away from the connected devices, preventing damage to their sensitive components. They are a crucial component in safeguarding computers and other electronics against electrical surges, ensuring their longevity and uninterrupted operation.Rate this question:

A device with a battery that continues to supply constant power even during brownouts or power outages is called a _________________
- A.
Plug strip
- B.
Surge suppressor
- C.
UPS
- D.
Circuit breaker
Correct Answer
C. UPSExplanation
A device with a battery that continues to supply constant power even during brownouts or power outages is called a UPS (Uninterruptible Power Supply). A UPS serves as a backup power source, providing uninterrupted electricity to connected devices, protecting them from power fluctuations or outages. Unlike plug strips, surge suppressors, and circuit breakers, a UPS has a built-in battery that allows it to provide continuous power supply, ensuring that devices remain operational during power disruptions.Rate this question:

Which of the following refers to a maintenance problem that is not caused by dirt or dust accumulation?
- A.
Erratic trackball response
- B.
Overheating
- C.
Disk fragmentation
- D.
Sticky keyboard keys
Correct Answer
C. Disk fragmentationExplanation
Disk fragmentation refers to a maintenance problem that is not caused by dirt or dust accumulation. Disk fragmentation occurs when files on a computer's hard drive are broken up into small pieces and scattered across different locations. This can slow down the computer's performance as it takes longer to retrieve and access the fragmented files. Unlike dirt or dust accumulation, which can cause overheating or sticky keyboard keys, disk fragmentation is a result of the way files are stored and accessed on a computer's hard drive.Rate this question:

Which part of a hard disk moves the fastest past the read and write heads and therefore is the most desirable location for commonly used files?
- A.
Outer edge
- B.
Halfway from center to outer edge
- C.
Side A
- D.
Near the center
Correct Answer
A. Outer edgeExplanation
The outer edge of a hard disk moves the fastest past the read and write heads because the rotational speed of the disk is constant. As the read and write heads are positioned closer to the center of the disk, the linear speed decreases. Therefore, the outer edge is the most desirable location for commonly used files as it allows for faster access and retrieval of data.Rate this question:
