-
USB
-
FireWire
-
IEEE 1284
-
IEEE 1449
Correct Answer(s)
A. USB
A. FireWireExplanation
USB and FireWire both use a serial bus architecture. A serial bus architecture is a type of data transfer that transmits data one bit at a time over a single communication channel. USB (Universal Serial Bus) is a widely used standard for connecting devices to a computer, such as keyboards, mice, and external storage devices. FireWire (also known as IEEE 1394) is another high-speed interface used for connecting devices like digital cameras, external hard drives, and audio/video equipment to a computer. Both USB and FireWire provide a reliable and efficient way to transfer data between devices using a serial bus architecture.Rate this question:

Before opening the system unit case, you should ______________.
-
Check free disk space.
-
Record CMOS settings.
-
Record monitor settings.
-
Disconnect the network cable.
Correct Answer
A. Record CMOS settings.Explanation
Before opening the system unit case, it is important to record CMOS settings. CMOS settings refer to the configuration settings of the computer's BIOS (Basic Input/Output System). These settings include information about the hardware installed in the computer, such as the hard drive, memory, and peripherals. By recording these settings, one can ensure that they are properly restored after opening the system unit case, as opening the case may require disconnecting certain components. This helps to avoid any potential issues or errors that may arise from incorrect or missing CMOS settings.Rate this question:

Zelda installs a SCSI host adapter and a single SCSI hard drive into her working Windows 9x PC. How should she set the termination?
-
Terminate only the host adapter.
-
Terminate only the hard drive.
-
Terminate both the hard drive and the host adapter.
-
Terminate neither. You only have to terminate external devices.
Correct Answer
A. Terminate both the hard drive and the host adapter.Explanation
When installing a SCSI host adapter and a single SCSI hard drive, both the hard drive and the host adapter should be terminated. Termination is necessary to prevent signal reflections and ensure proper communication between devices on the SCSI bus. In this case, since there is only one hard drive, termination is required for both the hard drive and the host adapter. Terminating only the host adapter or only the hard drive would result in improper communication and potential data errors. The statement "Terminate neither. You only have to terminate external devices" is incorrect because termination is required for internal SCSI devices as well.Rate this question:
