Q

USB 3 receptacles and connectors often have this color connector tab or housing

18
Q

USB 3.1; This compact form factor is intended to provide a single, consistent hardware interface for the standard. The connector is reversible, meaning it can be inserted either way up. The connector design is also more robust than the earlier types

A

USB Type C

19
Q

What is the maximum cable length for USB LowSpeed devices?

20
Q

What is the maximum cable length for USB FullSpeed and HighSpeed devices?

21
Q

What is the recommended maximum length for USB SuperSpeed-capable cables

22
Q

What 2 main factors determine video cable bandwidth?

A
  1. Resolution of the image
  2. The speed at which the image is redrawn, measured in hertz (Hz) or frames per second (fps).
23
Q

Each pixel in this type of display comprises cells with filters to generate the three additive primary colors red, green, and blue (RGB). Each pixel is addressed by a transistor to vary the intensity of each cell, therefore creating the gamut (range of colors) that the display can generate. The panel is illuminated by a light-emitting diode (LED) array or backlight

A

Liquid crystal display (LCD)

24
Q

Most widely used video
interface. It is ubiquitous on consumer electronics. Supports both video and audio, plus remote control and digital content protection (HDCP). Rated at either Standard (Category 1) or High Speed (Category 2)

A

High-Definition Multimedia Interface (HDMI)

25
Q

HDMI High Speed Cable is required for these v1.4 features

A

4k and refresh rates over 60 Hz

26
Q

How many Gbps can Premium High Speed HDMI cables support?

A

up to 18 Gbps

27
Q

How many Gbps can Ultra High Speed HDMI cables support?

A

up to 48 Gbps

28
Q

Developed as a royalty-free standard by the Video Electronics
Standards Association (VESA). Supports 4k, audio, and content protection

A

DisplayPort

29
Q

Which video cable supports daisy chaining, HDMI or DisplayPort?

A

DisplayPort

30
Q

Bandwidth of DisplayPort cable 2.0

A

up to 20 Gbps

31
Q

Can be used as a display interface; Version 2 of the standard supports links of up to 20 Gbps and supports daisy-chaining.

A

Thunderbolt Interface

32
Q

Version 3 of the standard supports links of up to 40 Gbps over a short, high-quality cable (up to .5 m/1.6 ft)

A

Thunderbolt interface

33
Q

Proprietary to Apple’s iPhone and iPad

A

Lightning interface

34
Q

the standard means of
connecting internal storage drives within a desktop PC. uses cables of up to 1 m (39 in.) terminated with compact 7-pin data connectors

A

Serial Advanced Technology Attachment (SATA)

35
Q

How many pins does the SATA power connector have?

36
Q

What is the speed of Version 1 SATA data cables?

37
Q

What is the speed of Version 2 SATA data cables?

38
Q

What is the speed of Version 3 SATA data cables?

39
Q

How many pins does a molex connector have?

40
Q

These cables connect power to internal storage devices; generally a legacy component; usually white or clear plastic

A

Molex connector

41
Q

used to attach peripheral drives with a 2 m (78 in) cable

A

external SATA (eSATA)
