Which of the following statements about High-Definition Multimedia Interface (HDMI) are true?
Each correct answer represents a complete solution. Choose two.
A.
It is capable of delivering the highest quality digital video and multi-channel digital audio on a
single cable.
B.
It is an interface primarily used to connect hard disk and CD drives in a computer.
C.
It is a new I/O bus technology that has more bandwidth than PCI and AGP slots.
D.
It has two types of connectors: Type A and Type B.
Explanation:
HDMI stands for High-Definition Multimedia Interface. It is a standard, uncompressed, and all-digital
audio/video interface. HDMI is capable of delivering the highest quality digital video and multichannel digital audio on a single cable. It provides an interface between any audio/video sources,
such as a DVD player or a computer and a digital television (DTV) or video monitor. HDMI transmits
all ATSC HDTV standards and supports 8-channel digital audio, with extra bandwidth to
accommodate future enhancements. HDMI has two types of connectors: Type A and Type B. Type A
and Type B connectors use 19 pins and 29 pins, respectively. The Type B connector is designed for
very high-resolution
displays that are expected in near future.
Answer option B is incorrect. Integrated Digital Electronics (IDE) is an interface primarily used to
connect hard disk and CD drives in a computer.
Answer option C is incorrect. PCI Express (PCIe), also known as 3rd Generation I/O (3GIO), is a type
of computer bus. It is a new I/O bus technology that has more bandwidth than PCI and AGP slots. It
uses two low-voltage differential pairs, at 2.5Gb/s in each direction. It is designed to replace PCI and
AGP expansion slots. The bus is available in several different bus widths: x1, x2, x4, x8, x12, x16, and
x32. PCIe is able to transfer data in both directions at a time. PCIe hardware will work on operating
systems that support PCI.
