CompTia A+: Chapter 3 Flashcards
Which of the following could be used with an analog monitor? (Choose two)
VGA & DVI-A [The A in both cable types is for analog, and analog monitors require analog signal. 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 the data transfer speed. What is the maximum speed of USB 2.0?
480 Mbps. [ USB 3.0 has a max speed of 5.0 Gbps, USB 3.1 is 10 Gbps, USB 3.2 is 20 Gbps, and USB 4.0 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?
“Always on” charging port. [It can be either USB 2.0 or 3.0.]
You are installing a replacement monitor on a desktop computer. Which of the following is true regarding a monitor’s refresh rate?
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).
Which of the following connector types is typically not associated with hard drive use?
DB-9 [ 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?
Micro USB / Mini USB [ 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.)
They can use both HDMI and HDMI mini connectors. They can transmit both audio and video.
Which of the following display interfaces is equivalent to DisplayPort with PCIe added in?
Thunderbolt. [ Intel and Apple collaborated on Thunderbolt to add PCIe to VESA’s DisplayPort and to make the resulting interface smaller and less expensive to connect. ]
Which of the following standards use the same connector? (Choose two)
USB4 is based on 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?
The connection should not be made between analog and digital.
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?
MOLEX [ 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?
Thunderbolt 3. [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? (Select all that apply)
Lightning, USB-C, and Micro-USB. [USB cables and eSATA cables can transmit power and data. A MOLEX connector is power only. A DB-9 is for serial cables and is data only]
Which of the following statements is true about eSATA cables and connectors?
eSATA standards limits throughput to 6Gbps. [ USB4 and Thunderbolt can get up to 40Gbps. Standard eSATA cables do not provide power, although there are versions of eSATA that do include power. The connectors for eSATA are larger than USB-C connectors.]
Which of the following is not an example of a connector for a standard peripheral input device?
MOLEX connectors [ MOLEX connectors are for PATA hard drives and optical drives. Peripherals most often use USB today but can also use D- sub connectors and audio devices such as jacks.]
