How many storage devices can be attached to a single SATA port?
One
You have a x8 PCIe storage adapter card - can you fit this in a x16 slot?
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?
Legacy video interface that supports digital only or digital and analog signaling.
What is a Video Graphics Array (VGA)?
Legacy video interface supporting analog-only signaling over a 15-pin D-Shell connector.
What is the Small computer system interface (SCSI)?
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?
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?
Legacy connector form factor used for serial (9-pin) and VGA (15-pin) interfaces.
What is an adapter cable?
,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?
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?
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?
,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?
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.
A support technician is working on a motherboard that is 12" x 9.6" and has seven
expansion slots. Which form factor is the technician working with?
The correct answer is ATX.
The Advanced Technology Extended (ATX) specification is the standard form factor for most
desktop PC motherboards and is 12 inches wide by 9.6 inches deep and can contain up to
seven expansion slots.
Which of the following statements regarding modern connectors and ports is untrue?
The correct answer and the one that is not true is that they use internal connection points.
They use input/output (I/O) port is the external connection point for a particular type of
bus interface and the connector is the part of a peripheral cable that inserts into a port with
the same shape.
Most connectors and input/output ports now use edge contacts that connect the cable wires
to the circuit boards.
, A lot of available connectors and ports have asymmetric design called keying to prevent
users from inserting them the wrong way around.
A reverisble connector is a connector that can be inserted into a socket in ether orientation.
The most typical variations of reversible connector's are Apple's Lighting connector and
USB Type C.
A computer is processing software instructions on the central processing unit. How is
all computer software broken down to be processed?
The correct answer is Binary.
All computer software works by running instructions in the central processing unit (CPU)
and computers process all the software and data as the ones and zeroes of binary code.
A support technician is isntalling a new SATA hard drive on a new computer. What is the best
type of cable connector the techncian will plug in to supply power to the drive?
The correct answer is 15-pin.
The technician will plug in a 15-pin SATA connector to connect the hard drive to the PC's
power supply.
A support technician opened the case to a PC and saw a square socket component.
What component has the support tech located?
The correct answer is CPU.
The support technican is removing the central processing unit (CPU). Unlike any other
connectors, the CPU socket is square, and the heat sink and fan are on top of it.
A video production company uses removeable media to transport multimedia files to partner
and customer sites. Often, the media has to be prepared with only very short notice. In the
