Domain 3.0 Flashcards
a computer is processing software instructions on the central processing unit. how is all computer software broken down to be processed?
bus
binary
RAM
system clock
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 zeros of binary code.
a manager directs a support technician to plug a device into the communications (COM) port. what port is the manager referring to?
IDE
SCSI
USB
serial
serial.
in windows, the serial port, or Recommended Standard #232 (RS-232) port, is also known as a communications (COM) port.
a support technician opened the case to a PC and saw a square socket component. what component has the support tech located?
RAM
adapter
CPU
drive
CPU.
the support technician 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 support technician is connecting an extended integrated drive electronics (IDE) cable to a PC’s motherboard, and knows that pin 1 on the cable must match up with pin 1 on the port. how can the tech know where pin 1 is on the cable?
pin 1 has a blue stripe
pin 1 has a black stripe
pin 1 has a red stripe
pin 1 has a gray stripe
pin 1 has a red stripe.
on the cable, pin 1 has a red stripe. manufacturers also key the connectors to prevent technicians from inserting them the wrong way around.
a video production company uses removable media to transport multimedia files to partner and customer sites. often, the media has to be prepared with only very short notice. in the past, the time taken to transfer files from the development workstations has resulted in delays and missed appointments. to mitigate this issue, the company has procured USB 3.2 Gen 2x2 storage devices and Windows PC workstation expansion cards. the devices and expansion cards support multiple USB hardware port types. which of the following adapter cables will enable the device to take the full advantage of the highest transfer rate?
type A to type A with USB 3 compatibility (denoted by a blue tab)
type B Micro to type A with USB 3 compatibility (denoted by a blue tab)
lightning to the type A
type C to type C
type C to type C.
type A ports and connectors enhanced to support USB 3 are denoted by a blue tab, but this physical interface only supports speeds up to 10 Gbps (USB 3.2 Gen 2x1)
type C connectors and ports support data transfers at the USB 3.2 Gen 2x2 20 Gbps rate. the connector is also much smaller than type A and is reversible. these improvements mean that other USB connector form factors are being phased out.
a support technician is installing a new SATA hard drive on a new computer. what is the best type of cable connector the technician will plug in to the supply power to the drive?
15-pin connector
7-pin connector
4-pin connector
USB connector
15-pin connector.
The technician will plug in a 15-pin SATA power connector to connect a hard drive to the PC’s power supply
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?
graphics
sound
NIC
Wi-Fi
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 is working on a motherboard that is 12” x 9.6” and has seven expansion slots. which form factor is a technician working with?
ATX
mATX
SFF
Mini-ITX
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.
a support technician managers mostly digital displays but has some older computers with the video cards that can support both analog and digital monitors. what type of video interface do these older computers have?
HDMI
DVI
VGA
DisplayPort
DVI.
the older computers have a digital visual interface (DVI) that supports both analog and digital outputs. DVI is no longer in active development and is only on older display devices and video cards.
a support technician needs to connect a USB port on a portable monitor to an HDMI port on a laptop to extended the laptop’s display. what kind of cable will the technician use to accomplish this?
SCSI
Adapter
EIDE
DVI
adapter.
the technician will use an adapter cable to connect the HDMI port on the laptop with the USB port on the monitor. an adapter cable has connectors for two different cable types at each end.
a support technician needs to install a legacy peripheral component interconnect (PCI) sound card. which of the following statements about PCI is NOT true?
PCI Express supersedes PCI
PCI uses parallel communications
The PCI card can fit into the PCIe slot
PCI is software compatible with PCIe
The PCI card can fit into the PCIe slot.
PCIe (Peripheral Component Interconnect Express) motherboards can include PCI ports to support legacy adapter cards, but PCI cards cannot fit into PCIe slots.
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?
through the top panel
through the side panel
through the rear panel
through the bottom of the rear panel
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 opened a PC case and observed a modern small computer system interface (SCSI) connector plugged into the motherboard. what can a technician know to be true about the connector?
it connects the hard disk
it’s using serial communications
it transfers data 1 bit at a time
it only supports 1 device at a time
it connects the hard disk.
in the past, SCSI could support both internal devices and external peripherals, such as scanners and printers, but now it’s used for the connection of internal hard disk drives.
a support technician plugged a monitor with a USB C cable connector into a USB C port on a computer, but the monitor would not function. why would the monitor not work?
it was not an HDMI cable
it was not a DisplayPort cable
it was not a Lightning cable
it was not a Thunderbolt cable
it was not a Thunderbolt cable.
USB-C may not work for display purposes without a Thunderbolt-capable cable. Thunderbolt uses the same connectors as a USB-C cable.
which of the following statements regarding modern connectors and ports is NOT true?
they use edge contacts
they use internal connection points
they sometimes use keying
they can be reversible
they use internal connection points.
an 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.
