Despite its limited color palette, CGA was widely used in the early days of personal computers and played a significant role in the development of computer graphics.
17.
The transfer corona uses this type of charge to attract toner to the paper.
Correct Answer
A. Positive
Explanation
The transfer corona uses a positive charge to attract toner to the paper. When the transfer corona applies a positive charge to the paper, it creates an electrostatic force that pulls the negatively charged toner particles towards the paper, allowing them to be transferred and adhered to the paper surface. This positive charge helps in the efficient transfer of toner from the imaging drum to the paper during the printing process.

Your system continuously reboots itself. Which of the following could be the problem?
Correct Answer
E. All of the above
Explanation
All of the above could be the problem because a continuous rebooting of the system can be caused by any of these issues. A bad system board can cause instability and lead to frequent reboots. A bad power supply can result in insufficient power being delivered to the system, causing it to reboot. A faulty adapter card can cause conflicts and crashes, leading to reboots. Finally, if the AC power is faulty, it can cause intermittent power supply issues, resulting in the system rebooting.
22.
You have an existing hard drive on your IDE adapter. You are installing a second hard drive and want the first hard drive to still be the bootable hard drive. How should you configure the second hard drive?
Correct Answer
C. Slave
Explanation
To ensure that the first hard drive remains the bootable drive, the second hard drive should be configured as a slave. This means that the second hard drive will be connected to the same IDE cable as the first hard drive but set to a lower priority. By configuring it as a slave, the system will prioritize booting from the first hard drive, allowing it to remain the bootable drive while still being able to access the second hard drive for additional storage or data.
23.
What type of interface has the fastest data transfer?
Correct Answer
D. SCSI
Explanation
SCSI (Small Computer System Interface) is a type of interface that has the fastest data transfer. It is a high-performance interface used for connecting devices such as hard drives, tape drives, and scanners to a computer. SCSI allows for parallel data transfer, meaning multiple bits of data can be transferred simultaneously, resulting in faster data transfer speeds compared to serial interfaces. Therefore, SCSI is the correct answer as it provides the fastest data transfer among the given options.
24.
