A. FireWire 800
B. USB 3.0
C. eSATA
D. Thunderbolt
B. The two most popular methods of manufacturing LCD panels are twisted nematic (TN) and in-plane switching (IPS). Of the two, IPS is regarded as having the best color representation in all angles, while TN is faster and less expensive. LED and plasma are not types of LCD panels.
B, C. A home server PC should be able to handle media streaming, as well as file and printer sharing. A dedicated print server is not likely needed, though, as the operating system can function as a print server. A gigabit NIC will be helpful to manage the network traffic, and a RAID array can help protect against hard drive failure.
B. The x8 card won’t completely fill the x16 slot, but it will work at x8 speeds of up- plugging is supported by the motherboard. Otherwise, the specification requires up-plugged devices to operate at only the x1 rate.
B. Secure Boot is an option enabled in system firmware. BIOS is not technically advanced enough to manage Secure Boot, but its successor UEFI is.
A. DDR has 184 pins, DDR2 and DDR 3 have 240 pins, and SODIMMs can have 72, 100, 144, 200, or 204 pins.
D. Hyperthreading-capable processors appear to the operating system to be two processors. As a result, the operating system can schedule two processes at the same time on the same physical core.
A. Dot-matrix printers are impact printers and typically require paper that always feeds at a consistent rate. To achieve this, the paper will have holes on the outside edges, which is fed into the printer using a tractor feed mechanism.
D. Embedded MultiMediaCard (eMMC) can be permanently embedded on the circuit board of a cheaper or smaller mobile device. All of the other flash memory standards, such as CompactFlash, xD, miniMMC, and microMMC are designed to be removable.
A. ATX motherboards are common in desktop computers and measure 12″ × 9.6″. They are the largest motherboards commonly used in personal computers today.
C. The motor that makes the print head carriage move is also often called the carriage motor or carriage stepper motor. It has a belt attached to it, the carriage belt, which moves the print head carriage back and forth.
A, D. For an audio/video editing workstation, you should maximize the audio and video capabilities, including having at least two large monitors. Videos also take a lot of disk space, so significant storage space is required.
A, D. Intel’s Virtualization Technology (Intel VT) is needed to support virtualization. It’s enabled in the BIOS, not the operating system.
A. Graphic design (or CAD/CAM) workstations require solid CPU power, RAM, and a high-end video card. Hard drive storage is the least important upgrade for these types of users.
C. The most common analog video connector is a VGA connector.
A. Refresh rate defines the vertical scan frequency of a monitor and determines how many times, in one second, an image can be redrawn on the screen. Many LCD monitors have a fixed refresh rate.
D. Thunderbolt v1 and v2 both provide 20Gbps of data bandwidth. In addition, Thunderbolt ports power the attached peripherals with 18V and 9.9W of power.
