Q

Two or more forms share a common axis. Built around a central conductor or core to carry data from point to point. Core has an insulator wrapped around it, a shield over the insulator, and a nonconductive sheath around the shielding. Shielding prevents core from emanating signals externally from cable.RG-6 used in television/digital cable– And high-speed Internet over cable.

A

Thunderbolt

17
Q

Video and audio stream. All digital, no analog.20-meter distance before losing too much signal.19-pin (Type A) connector. Has five different connectors with different number of pins.

A

High-Definition Multimedia
Interface (HDMI)

18
Q

Digital information sent in packetized form– Like Ethernet and PCI Express– Carries both audio and video
Compatible with HDMI and DVI– Passive adapter– DisplayPort -> HDMI– DisplayPort -> DVI. Connects mostly to TV and computer monitor using a USB connector.

A

DisplayPort

19
Q

Single and dual link– Single link; 3.7 Gbps (HDTV at 60 fps)– Dual link; 7.4 Gbps (HDTV at 85 fps)– No audio support. All connectors are D shaped. Wiring is shaped differently on weather on connector is single linked or dual linked. Includes digital and analog signals which makes it popular for LCD and plasma TVs. The single maximum data rate is 3.96 Gbps and the dual link maximum data rate is 7.92 Gbps.
