What is the throughput of an AGP 8X video card?
- A.
533 MBps
- B.
1 GBps
- C.
264 MBps
- D.
2.1 GBps
Correct Answer
D. 2.1 GBpsExplanation
The throughput of an AGP 8X video card is 2.1 GBps. AGP 8X is a type of accelerated graphics port that allows for faster data transfer between the video card and the computer's memory. The "8X" refers to the multiplier of the base AGP speed, which is 66 MHz. Therefore, the throughput of an AGP 8X video card is calculated by multiplying the base speed (66 MHz) by the multiplier (8X), resulting in a throughput of 528 MHz. Since 1 byte is equal to 8 bits, we divide 528 MHz by 8 to get the throughput in bytes per second, which is 66 MBps. Finally, converting MBps to GBps, we divide 66 by 1024, resulting in a throughput of 2.1 GBps.Rate this question:

Which of the following will facilitate usage of SCSI devices on a mother board that has default IDE interfaces?
- A.
Accurate CMOS configuration
- B.
A SCSI host adapter
- C.
RAM Upgrade
- D.
BIOS Upgrade
Correct Answer
B. A SCSI host adapterExplanation
A SCSI host adapter is required to facilitate the usage of SCSI devices on a motherboard that has default IDE interfaces. SCSI (Small Computer System Interface) is a high-speed interface that allows for the connection of multiple devices, such as hard drives, scanners, and printers. Since the motherboard only has IDE interfaces by default, which are not compatible with SCSI devices, a SCSI host adapter is needed to bridge the gap and enable communication between the SCSI devices and the motherboard. This adapter acts as an interface between the SCSI devices and the IDE interfaces on the motherboard, allowing for the seamless integration and usage of SCSI devices.Rate this question:

A higher DPI value indicates a higher resolution and better print quality, as more dots can be printed per inch. Therefore, DPI is the appropriate unit to measure the quality of an inkjet printer.Rate this question:

Correct Answer
C. The nozzles can get obstructedExplanation
The common disadvantage of inkjet printers is that the nozzles can get obstructed.

This can lead to poor print quality and the need for frequent maintenance or cleaning of the printer.Rate this question:

Correct Answer
A. It produces vivid color printsExplanation
An advantage of using a solid ink printer instead of an inkjet printer is that it produces vivid color prints.

This technology allows for better color saturation and sharpness in the prints, making them visually appealing and high-quality.Rate this question:

Correct Answer
C. 63Explanation
The correct answer is 63. The maximum number of devices that can be connected through a single firewire interface is 63. Firewire, also known as IEEE 1394, is a high-speed serial bus interface that allows for the connection of various devices such as computers, cameras, and external hard drives. It uses a daisy-chain topology, where devices are connected in a chain-like manner, and each device has a unique identifier. The maximum number of devices that can be connected in a daisy-chain configuration is limited to 63 due to addressing limitations.Rate this question:
