ROM stands for _________?
- A.
Read On Memory
- B.
Read Only Maker
- C.
Read On Motherboard
- D.
Read Only Memory
Correct Answer
D. Read Only MemoryExplanation
ROM stands for Read Only Memory. ROM is a type of computer memory that is non-volatile, meaning the data stored in it is not lost when the power is turned off. It is called "Read Only" because the data stored in ROM can only be read and cannot be modified or erased. ROM is commonly used to store firmware, which contains the instructions that are permanently programmed into a device.Rate this question:

The brain of the computer is the ______________?
- A.
RAM
- B.
ROM
- C.
BIOS
- D.
CPU
Correct Answer
D. CPUExplanation
The brain of the computer is the CPU (Central Processing Unit). It is responsible for executing instructions, performing calculations, and managing the flow of data within the computer system. The CPU acts as the control center and performs the majority of the processing tasks, making it the most important component in a computer. RAM (Random Access Memory) and ROM (Read-Only Memory) are types of memory used by the computer, while BIOS (Basic Input/Output System) is responsible for initializing hardware components during the boot-up process. However, none of these components function as the brain of the computer like the CPU does.Rate this question:

A virtual storage system can exist at a location such as your ISP, where you can store data from anywhere in the world.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
A virtual storage system allows users to store data remotely, typically in a cloud-based environment. This means that the storage system can be located at a location such as your ISP (Internet Service Provider), where you can access and store data from anywhere in the world. This flexibility and accessibility are key features of virtual storage systems, making the statement true.Rate this question:

How can you access a remote storage system?
- A.
Start a Web browser and navigate to that site
- B.
Through your e-mail program
- C.
Using a USB memory key
- D.
Log on with a valid ID and password
Correct Answer
D. Log on with a valid ID and passwordExplanation
To access a remote storage system, the correct way is to log on with a valid ID and password. This is because remote storage systems are usually protected and require authentication to ensure only authorized users can access the data. Starting a web browser and navigating to the site may not necessarily grant access to the remote storage system, as it depends on the specific setup. Using an e-mail program or a USB memory key is also unlikely to provide access to the remote storage system, as these methods are typically used for transferring or storing data rather than directly accessing the system.Rate this question:

Why should you save your files to a storage device?
- A.
To prevent data loss if the computer is turned off
- B.
To store information from RAM onto the storage device
- C.
To have a copy of the data
- D.
None
Correct Answer(s)
A. To prevent data loss if the computer is turned off
B. To store information from RAM onto the storage device
C. To have a copy of the dataExplanation
Saving files to a storage device is important for several reasons. Firstly, it helps prevent data loss if the computer is turned off unexpectedly or experiences a power outage. By saving files to a storage device, you ensure that your data is protected and can be easily recovered even if the computer shuts down abruptly. Additionally, saving files to a storage device allows you to store information from the computer's RAM onto the device, freeing up memory and improving the computer's performance. Lastly, saving files to a storage device provides you with a copy of the data, allowing you to access and use it on different devices or in case the original files are accidentally deleted or corrupted.Rate this question:

The best way to gain more RAM for processing a newsletter is:
- A.
Close any files you are not currently using.
- B.
Close any application programs you are not currently using.
- C.
Restart the computer.
- D.
Only the first one is right
Correct Answer(s)
A. Close any files you are not currently using.
B. Close any application programs you are not currently using.Explanation
Closing any files and application programs that are not currently being used is the best way to gain more RAM for processing a newsletter. When files and applications are open, they consume memory resources, and closing them frees up RAM for other tasks. Restarting the computer can also help in freeing up RAM, but it is not the most efficient solution as it may close all running processes and disrupt other ongoing tasks. Therefore, the first two options are the correct ones for gaining more RAM.Rate this question:

Why is RAM considered volatile?
- A.
It disappears when the computer is shut down or reset.
- B.
It uses up only as much memory as it needs for processing.
- C.
It always uses a certain amount of memory for Windows.
Correct Answer
A. It disappears when the computer is shut down or reset.Explanation
RAM, or Random Access Memory, is considered volatile because it loses all data stored in it when the computer is shut down or reset. Unlike other types of memory, such as hard drives or solid-state drives, RAM does not retain its contents when power is removed. This is because RAM relies on electrical currents to store and retrieve data, and without power, these currents are disrupted and the data is lost. Therefore, RAM is temporary and meant for short-term storage while the computer is powered on.Rate this question:

Which of the following retains the information it's storing when the power to the system is turned off?
- A.
CPU
- B.
ROM
- C.
RAM
- D.
Other
Correct Answer
B. ROMExplanation
ROM (Read-Only Memory) is a type of computer memory that retains its stored information even when the power to the system is turned off. This is because ROM is non-volatile memory, meaning it does not require power to maintain its data. Unlike RAM (Random Access Memory) which is volatile and loses its data when power is lost, ROM is designed to store permanent or semi-permanent data that is essential for the system's operation, such as firmware or system instructions. Therefore, ROM is the correct answer as it retains information even when the power is off.Rate this question:

If I need to store my resume and I have about one-half of a page completed in Microsoft Word, what is the minimum amount of memory I will need to store the essay?
- A.
A gigabyte
- B.
A kilobyte
- C.
A megabyte
- D.
A terabyte
Correct Answer
B. A kilobyteExplanation
Since the resume is only half a page long in Microsoft Word, it would require a very small amount of memory to store. A kilobyte (KB) is the smallest unit of memory commonly used, and it is sufficient to store a resume of this size. A gigabyte (GB), megabyte (MB), and terabyte (TB) are much larger units of memory and would be excessive for storing a half-page resume.Rate this question:
