- 1.
Contiguous files are created by...
- A.
Disk cleanup
- B.
Disk defragmenter
- C.
System restore
- D.
All of the above
Correct Answer
B. Disk defragmenterExplanation
Disk defragmenter is the correct answer because it is a tool that reorganizes the data on a computer's hard drive, making it more efficient and improving performance. When files are saved or deleted on a computer, they can become fragmented, meaning that different parts of the file are stored in different locations on the hard drive. Disk defragmenter brings all the fragmented parts of a file together and stores them in contiguous locations on the hard drive, making it easier and faster for the computer to access the file.Rate this question:

What is a very common symptom of the IDE cable for a floppy drive being connected upside down?
- A.
Drive led never lights
- B.
Drive led is permanently lit
- C.
Drive led flashes
- D.

IRQ lines ………
- A.
Are not used on modern motherboards and processors
- B.
Allow devices to interrupt the flow of programs in the CPU
- C.
Use USB type connectors
- D.
All of the above
Correct Answer
B. Allow devices to interrupt the flow of programs in the CPUExplanation
IRQ lines are used on modern motherboards and processors to allow devices to interrupt the flow of programs in the CPU. This means that when a device needs to communicate with the CPU, it can send an interrupt signal through the IRQ line, causing the CPU to temporarily pause its current task and handle the interrupt. This allows for efficient multitasking and ensures that important tasks are prioritized. The statement "All of the above" is correct because it encompasses the previous statements about IRQ lines being used on modern motherboards and processors and allowing devices to interrupt the flow of programs in the CPU.Rate this question:

Which file extension does not apply to a library file used by an executable program?
- A.
.lib
- B.
.dll
- C.
.exe
- D.
None of the above, they are all library file extensions
Correct Answer
C. .exeExplanation
The file extension .exe does not apply to a library file used by an executable program. The .exe extension is used for executable files, which are the files that can be directly run by the operating system. Library files, on the other hand, have extensions like .lib and .dll, which are used to store reusable code that can be shared by multiple programs. Therefore, the correct answer is .exe.Rate this question:

A laser printer which starts to print smudgy vertical lines on the paper as well as the desired image is probably suffering from
- A.
Corona wire failure
- B.
A failure to charge the drum properly
- C.
A failure to clean the drum properly
- D.
A failure to feed the paper properly
Correct Answer
C. A failure to clean the drum properlyExplanation
If a laser printer starts to print smudgy vertical lines on the paper along with the desired image, it is likely suffering from a failure to clean the drum properly. The drum in a laser printer is responsible for transferring toner onto the paper, and if it is not cleaned properly, excess toner may remain on the drum's surface. This excess toner can then be transferred onto the paper, resulting in smudgy vertical lines.Rate this question:
