A. PCI
B. PCIe
C. VGA
D. DVI

Answer 1

B. PCIe

PCI is an Older Type of slot that is slower and less desirable for Video Cards.
VGA/DVI are not Slot Types.

Question 2

Which port is used Exclusively for external hard drives?

A. FireWire
B. USB
C. eSATA
D. PS/2

Answer 2

C. eSATA

FireWire and USB can be used for External Hard Drives, but they also have other uses.
PS/2 is an OLD Port used for Keyboards and Mice, NOT Hard Drives.

Question 3

A. Type-A
B. Type-B
C. Mini-B
D. Micro-B

Answer 5

B. Type-B

Type-A is the Standard Full Size USB connector on a PC.
Mini-B and Micro-B plug into smaller devices.

Question 6

Which of these is NOT a Flat-Panel Display?

A. OLED
B. LCD
C. Plasma
D. CRT

Answer 6

D. CRT

All others ARE flat panel displays.

Question 7

Which of these Ports is Physically Identical?

A. USB Type-A and USB Type-B
B. Thunderbolt and Mini DisplayPort
C. DisplayPort and FireWire
D. DVI and VGA

Answer 7

B. Thunderbolt and Mini Display Port

Question 8

What is the purpose of a wheel on a mouse?

Answer 8

Scrolling the Display

Question 9

A Video Camera that works only when connected to a computer is a?

Answer 9

Webcam

Question 10

A Receipt Printer on a cash register is likely to be what kind of printer?

Answer 10

Thermal

Question 11

Expansion Slots?

Answer 11

Motherboards have Expansion Slots, into which you can install Expansion Cards that add capabilities to the computer. Video Adapter for example, or you can add a type of port the mother board doesn’t natively support such as FireWire or eSATA.

Question 12

Video Card?

Answer 12

Also called a Display Adapter, provides ports to connect to an external display and acts as a graphics processor interface between the OS and the Monitor.

Question 13

Audio Card?

Answer 13

Also known as a Sound Card, provides ports to connect speakers, headphones, microphones and other digital audio input and output devices.

Question 14

Network Card?

Answer 14

Also called a Network Interface Card (NIC), enables you to connect to a local area network. A network card can be wired or wireless. If wired, it has a RJ-45 Port. If Wireless, it may have a small external antenna. NICs have a 48-bit Hexadecimal Media Access Control (MAC) address that uniquely identifies the NIC on the LAN.

Question 15

Expansion Slot Types?

Answer 15

PCI Express (PCIe) 3.0 dominates the market. The term applies to both the slot and the bus that carries data from the slot to the system bus. Each slot has between 1 and 32 independent lanes that carry data and a slot has a numeric designation to describe how many lanes it has.

PCI (Peripheral Component Interconnect) is an older general-purpose slot type.

Mini-PCIe - Some laptops have these slots that accept smaller versions of the same kinds of expansion cards that desktop PC’s use.

Question 16

Ports from Fastest to Slowest - GO? Rank Each:

A. FireWire (IEEE 1394)
B. eSATA
C. Thunderbolt
D. USB

Answer 16

C. Thunderbolt > D. USB > A. FireWire (IEEE 1394) > B. eSATA

Thunderbolt 1 runs at 10 Gbps.
Thunderbolt 2 runs at 20 Gbps.
Thunderbolt 3 runs at 40 Gbps. (USB 3.1 & Type-C Ports)
FireWire 400 runs at 400 Mbps.
FireWire 800 runs at 800 Mbps.
eSATA runs at 1.5, 3, or 6 Gbps.

Question 17

Other Ports?

RJ-45
3.5-mm Audio
PS/2
RJ-11
Legacy Parallel
Legacy Serial

Answer 17

RJ-45 = Ethernet Networking
3.5-mm Audio = Headphones, Microphones, Speakers
PS/2 = Old Port for Mice/Keyboards, it’s Rounded
RJ-11 = Traditional Modems and Landline Telephones
Legacy Parallel = Old Printers, 25-pin D-Shaped Connector, mostly replaced by USB now.
Legacy Serial = Old low-speed devices, 9-pin D-Shaped, mostly replaced by USB now.

Question 18

Get to know your USB Connector Types?

Type-A
Type-B
Mini-B
Micro-B
Type-C

Answer 18

Type-A = The Standard rectangular USB ports on most desktop and laptop PCs and on one end of most USB cables.
Type-B = Near-Square connector used most for full-size peripherals such as printers - replacing Legacy Parallel.
Mini-B = Smaller peripheral connector for smartphones, digital cameras, MP3 Players, and so on. Less durable than Micro-B, become more rare.
Micro-B = For smaller peripheral devices. Original Micro-B is more compact than Mini-B.
Type-C = Compact connector for both larger and smaller devices. To eliminate problems of inserting USB connectors upside down, Type-C can be inserted in two orientations. Type-C will eventually replace ALL previous USB connectors.

Question 19

Monitor Types?

LCD
FPD
CCFL
LED
OLED
CRT

Answer 19

LCD = Liquid Crystal Display - which has a backlit layer of liquid crystal molecules called subpixels sandwiched between polarizing filters.
FPD = Flat Panel Display - thin, lightweight, has very little power.
CCFL = Cold Cathode Fluorescent Lamps - Older backlights and last longer.
LED = Light Emitting Diode - use grid of many tiny lightbulbs, when powered the lightbulbs glow.
OLED = Organic Light Emitting Diode - A more efficient variant of LED.
CRT = Bulky because of a large cathode ray tube. Very OLD, and Heavy.
