Which of the following could be used with an analog monitor? (Choose two.)
A. HDMI
B. DVI-A
C. DVI-D
D. DisplayPort
E. VGA
B,E. - Analog monitors require an analog signal. VGA is an analog video standard and will work. DVI-A is also analog. (DVI-I would work as well.) HDMI, DVI-D, and DisplayPort are all digital standards.
You are attaching an external hard drive to a computer with USB 2.0 ports. The user is concerned about data transfer speed. What is the maximum speed of USB 2.0?
A. 480 Mbps
B. 5 Gbps
C. 10 Gbps
D. 20 Gbps
A. USB 2.0 has a maximum speed of 480 Mbps. USB 3.0 is 5 Gbps, USB 3.1 is 10Gbps, USB 3.2 is 20 Gbps, and USB 4 is up to 40 Gbps.
You got a new desktop computer for a designer at your company. On the front panel is a rectangular yellow USB port. What does that mean?
A. It’s USB 2.0
B. It’s USB 3.0
C. It’s a port capable of charging devices even with the system powered off.
D. It’s a port to be used with USB-C compatible devices.
C. A yellow USB port is an “always on” charging port. It could be either USB 2 or USB 3. USB-C connectors are oval in shape vs. the older rectangular USB connectors.
You are installing a replacement monitor on a desktop computer. Which of the following is true regarding a monitor’s refresh rate?
A. As long as the graphics adapter can refresh the image at a particular rate, the attached monitor can accommodate that refresh rate.
B. The refresh rate is normally expressed in MHz.
C. The refresh rate is normally selected by using the controls on the front panel of the monitor.
D. As you lower the resolution, the maximum refresh rate allowed tends to increase.
D. As you lower the resolution, the maximum refresh rate allowed tends to increase. The refresh rate is most often expressed in cycles per second (Hz), not millions cycle per second MHz). You must usually select the refresh rate that you want from the display settings dialog boxes, not through the monitor’s built-in menu system, although the monitor can often tell you the refresh rate that you’re using. Finally, both the monitor and adapter must agree on the refresh you select. if either device does not support a particular refresh rate, such a rate cannot be used.
Which of the following connector types is typically not associated with hard drive use?
A. USB-C
B. eSATA
C. DB-9
D. SCSI
C. DB-9 connectors are most often used with serial cables and are not associated with hard drives. USB-C, eSATA, and SCSI are examples of connectors used with hard drives.
The company photographer is interested in buying a new digital camera. He wants to be able to plug it directly into his laptop to transfer pictures for editing. What type of connector will most likely be on his camera?
A. Mini-USB
B. Thunderbolt
C. Molex
D. Lightning
A. For smaller electronic devices such as cameras, micro-USB and mini-USB connectors are common. Thunderbolt is primarily used for video. Molex is a power connector. Lightning is the Apple proprietary connector.
You are installing a new video card that has an HDMI port. Which of the following is true about HDMI cables? (Choose all that apply.)
A. They can transmit analog or digital signals.
B. They can transmit audio as well as video.
C. They are not used to connect to projectors.
D. They can use HDMI or mini-HDMI connectors.
B,D - HDMI cables transmit digital video and audio signals. They can be used to connect to projectors or monitors. HDMI cables can have standard HDMI connectors, mini-HDMI connectors, or micro-HDMI connectors.
Which of the following display interfaces is equivalent to DisplayPort with PCIe added in?
A. Thunderbolt
B. HDMI
C. DVI
D. VGA
A. Intel and Apple collaborated on Thunderbolt to add PCIe to BESA’s DisplayPort and to make the resulting interface smaller and less expensive to connect. HDMI, DVI, and VGA are not equivalent to Display Port with PCIe added in.
Which of the following standards use the same connector? (Choose two.)
A. eSATA
B. Thunderbolt 3
C. USB4
D. USB 2.0
E. Mini-USB
B,C. USB4 is based on the Thunderbolt 3 specifications, and both natively use USB-C connectors.
How do you connect a DVI-A interface on a peripheral to a DVI-D interface on the computer?
A. With a DVI-I cable
B. With a cable that is terminated on one end with a DVI-A connector and on the other end with a DVD-D connector.
C. You wouldn’t interconnect those two interfaces.
D. With a standard DVI cable.
C. Such a connection should not be made. DVI-I cables act like Univeral cables’ they can connect two DVI-A interfaces or two DVI-D interfaces with adapters. Natively, they are used to connect two DVI-I interfaces, both of which are configured as either analog or digital. They are unable to convert the analog signal to a digital one, however. Analog and digital DVI interfaces are too disparate to interconnect.
A technician says he needs to provide power to an older IDE hard drive and a DVD-ROM in a desktop. The computer now has a new fully modular power supply, and the technician wants to know what type of power connectors he should use. What do you tell him?
A. SATA
B. SCSI
C. Serial
D. Molex
D. A Molex connector is a power connector for IDE (PATA) storage devices. This includes hard drives and optical drives.
Which of the following connectors is oval shaped?
A. Micro-USB
B. Mini-USB
C. Thunderbolt 2
D. Thunderbolt 3
D. Thunderbolt 3 uses the oval -shaped USB-C connector. Thunderbolt 2 used a proprietary connector that was more of a square. Micro-USB and mini-USB connectors look more like trapezoids.
Which of the following connector types are capable of conducting power and transmitting data? (Choosing all that apply.)
A. Lightning
B. Molex
C. USB-C
D. DB-9
E. Micro-USB
A,C,E. USB cables and eSATA cables can transmit power and data. You will find Lightning, only. A DB-9 is for serial cables and is data-only.
Which of the following statements is true about eSATA cables and connecters?
A. eSATA cables provide power and data to devices.
B. eSATA connectors are smaller than USB-C connectors.
C. eSATA is faster than USB4 and Thunderbolt 3.
D. eSATA maximum throughput is 6 Gbps.
D. The eSATA standards limit throughput to 6 Gbps, which is much slower than USB4 and Thunderbolt 3, both of which can get to 40 Gbps. Standard eSATA cables do not provide power, although there are versions of eSATA that do include power. The connectors are larger than USB-C connectors.
Which of the following is not an example of a connector for a standard peripheral input device?
A. 1/8” jack
B. Molex
C. D-sub
D. USB
B. Peripherals most often use USB today, but they can also use D-sub connectors (rarely), and audio devices such as microphones an speakers use 1/8” jacks. Molex connectors are power connectors for PATA hard drives and optical drives.
