What is High-Definition Multimedia Interface (HDMI)? - correct answers.Digital
audio/video interface developed for use on both consumer electronics and computer
equipment.
What is a DisplayPort? - correct answers.Digital audio/video interface developed by
VESA. DisplayPort supports some cross-comptability with DVI and HDMI devices.
What is the Thunderbolt connector? - correct answers.Thunderbolt can be used as a
display interface (like DisplayPort) and as a general peripheral interface (like USB 3).
The latest version uses USB-C connectors.
What is the Lightning connector? - correct answers.Proprietary connector and interface
used by Apple iPhone and iPad devices.
What is the Serial Advanced Technology Attachment (SATA) cable? - correct
answers.Serial ATA is most widely used interface for hard disks on desktop and laptop
computers. It uses a 7-pin data connector with one device per port. There are three
SATA standards specifying bandwidths of 1.5 Gb/s, 3 Gb/s, and 6 Gb/s respectively.
SATA drives also use a new 15-pin power connector, though adapters for the old style
4-pin Molex connectors are available. External dries are also supported via eSATA
interface.
What is a Molex connector? - correct answers.Legacy power connector for internal
devices such as hard drives and optical drives.
,What is the external SATA (eSATA) connector? - correct answers.Variant of SATA
cabling designed for external connectivity.
What is the nominal data rate of a USB port supporting Gen 3.2 2x1? - correct
answers.10 Gbps
A technician connects a single port on a graphics card to two monitors using two cables.
What type of interface is being used? - correct answers.Both DisplayPort and
Thunderbolt interfaces support this type of daisy-chaining.
True or false? USB-C ports and connectors are compatible with Apple Lightning
connectors and ports. - correct answers.False, An adapter cable is required.
A technician has removed an adapter card from a PC. Should the technican obtain and
install a blanking plate to complete the service operation? - correct answers.Yes. The
fan system is designed to draw cool air across the motherboard and blow out warm air.
Large holes in the chassis disrupt this air flow. Also, dust will be able to settle on the
system componenets more easily. A blanking plate covers the empty slot in the case.
A techncian is completed a storage upgrade on an older computer. Examining the
power supply, the technician notices that only two of the five plugs of the type shown in
the exhibit are connected to devices. What is the purpose of these plugs, and can some
be left unconnected? - correct answers.A Molex cable is a power cable used for storage
devices that requries more power than cab be supplied over most internal bus types.
Unused connectors do not pose any problem (though they should be secured with cable
ties to minimize disruption of air flow. Note that Molex is a legacy connector fmorat.
Most drives use SATA power connectors these days.
What is the Peripheral Component Interconnect Express (PCIe)? - correct
answers.Internal expansion bus that uses serial point-to-point communications between
device. Each link can comprose one or more lanes (x1, x2, x4, x8, x12, x16, or x32).
Each lane supports a full-duplex transfer rate of 250 MB/s (v1.0) up to about 4 GB/s
(v5.0).
What is a Peripheral Component Interconnect (PCI) - correct answers.Legacy internal
expansion bus supporting 32-bit parallel transfers working at 33 mHz.
What is the Advanced Technology Extended (ATX) - correct answers.Standard PC
case, motherboard, and power supply specification. Mini-, Micro-, and Flex- ATX specify
smaller board designs.
What is the Information Technology Extended? - correct answers.Series of motherboard
form factors desgined for small form factor (SFF) computers and appliances.
,What are headers? - correct answers.Connector on the motherboard for internal
cabliing, such as fan power and front panel ports and buttons.
What is a video card? - correct answers.Adapter that handles graphics processing and
output to a dispaly device over one or more video interface ports.
What is a sound card? - correct answers.Adapter card providing sound playback and
recording functionality. A number of different audio ports exist on modern computer
motherboards or on specialist sound cards. Commonly, audio ports may be marked as:
audio out, audio on, speaker out, microphone input/mic, and headphones.
What is a network interface card? - correct answers.Adapter card that provides one or
mpre Ethernet ports for connecting hosts ot a network so that they can exchange data
over a link.
What is the bandwidth of a PCIe v2.0 x16 graphic adapter? - correct answers.8 GBps in
each direction (full-duplex). PCIe v2 supports 500 MBps per lane.
What type of motherboard socket is used to install system memory? - correct
answers.Dual inline memory module (DIMM).
How many storage devices can be attached to a single SATA port? - correct
answers.One
You have a x8 PCIe storage adapter card - can you fit this in a x16 slot? - correct
answers.Yes - this is referred to as up-plugging. On some motherboards it may only
function as a x1 device though.
What is Digital Visual Interface? - correct answers.Legacy video interface that supports
digital only or digital and analog signaling.
What is a Video Graphics Array (VGA)? - correct answers.Legacy video interface
supporting analog-only signaling over a 15-pin D-Shell connector.
What is the Small computer system interface (SCSI)? - correct answers.Legacy
expansion bus standard allowing for the connection of internal and external devices.
Each device on a SCSI bus must be allocated a unique ID. The bus must also be
terminated at both ends.
What is the Integrated Drive Electronics? - correct answers.Legacy mass storage bus,
most commonly implemented as extended IDE (EIDE) and also referred to as a parallel
advanced technology attachment (PATA). Each IDE controller port supports two
devices connected over a ribbon cable with three connectors (controller, primary device,
and secondary device).
, What is DB-9? - correct answers.Legacy connector form factor used for serial (9-pin)
and VGA (15-pin) interfaces.
What is an adapter cable? - correct answers.Peripheral cable converting between
connector form factors or between signaling types, such as DisplayPort to HDMI.
A support technician is installing a PCIe card that will use a combination of system
memory and dedicated memory. What type of card is the tech installing? - correct
answers.The correct answer is Graphics.
The support technician is installing a graphics adapter, also called a video card.
Graphics adapters can have up to 12 GB of dedicated memory and may use a mix of
dedicated and shared or system, memory.
A support technician opened a PC case and observed a small computer system
interface (SCSI) connector plugged into the motherboard. What can the technician know
to be true about the connector? - correct answers.The correct answer is that it is likely
to connected to the hard disk.
SCSI connectors are commonly used to connect to hard disks, as well as other storage
devices like tape drives, CD/DVD drives, and external storage drives.
Each device on a wide SCSI bus must be configured with a unique ID, from 0 to 15.
While a serial interface essentially transfers 1 bit at a time, a parallel interface such as a
SCSI transfers 8 bits (1 byte) or more and requires more wires in the cable and more
pins in the connectors.
One SCSI host bus adapter (HBA) can control multiple devices attached by internal
ribbon cables or external SCSI cables.
A support technician needs to connect the USB port on a portable monitor to an HDMI
port on a laptop to extend the laptop's display. What kind of cable will the technician use
to accomplish this? - correct answers.The correct answer is an adapter cable.
The technician will us an adapter cable to connect the HDMI port with a USB port on the
monitor. An adapter cable has connectors for two different cable types at each end.
A support technician needs to install an optical disk drive in a new tower. Which panel
should be removed so that the technician can gain access to the optical drive and
connect the cables? - correct answers.The correct answer is through the side panel.
The technician will be able to hook up the optical media drive through the side panel. A
tower case has a side cover that a technician can remove by sliding the panel from its
housing.
