Identify the ports in the image given below.
Answer: 
Explanation:
Universal Serial Bus (USB) is a high speed bus standard developed by Compaq, IBM,
DEC, Intel, Microsoft, NEC, and Northern
Telecom. It provides the Plug and Play capability of Windows to external hardware devices. USB
supports hot plugging, which means that a
USB device can be installed or removed while the computer is running. A single USB port can be used
to connect up to 127 peripheral devices,
such as CD-ROM drives, tape drives, keyboards, scanners etc. USB 1.1 has a maximum data transfer
rate of 12 Mbps, whereas USB 2.0 has a
maximum data transfer rate of 480 Mbps. USB 2.0 is fully backward compatible with USB 1.1.
DVI stands for Digital Visual Interface. It is a standard for high speed, high resolution digital display
invented by Digital Display Working Group
(DDWG). DVI accommodates analog and digital interfaces with a single connector. New video cards
have DVI as well as VGA ports built into
them. Most of LCD monitors come with a 15-pin VGA connection cable, even if they are capable of
handling digital signals coming from DVI
connections. However, some monitors come with both types of cables. DVI has three main
categories of connectors. They are: DVI-A, DVI-D,
and DVI-I. DVI-A is an analog-only connector, DVI-D is a digital-only connector, and DVI-I is an
analog/digital connector. DVI-D and DVI-I
connectors are of two types: single link and dual link. DVI supports UXGA and HDTV with a single set
of links. Higher resolutions such as 1920
x 1080, 2048 x 1536, or more can be supported with dual links.
S-Video, also known as Y/C video, stands for Super-Video. It is a technology for video transmission.
Using this technology, the video is
transmitted into two separate signals. One is used for color, and the other for brightness. Sometimes
S-Video signals are considered as a
type of component video signal. However, its quality is inferior to other complex component video
schemes such as RGB. This technologyproduces sharper images than those produced by composite video, which carries the entire set of
signals in a single line. For using S-Video,
the device sending the signal must support S-Video output and the device receiving the signal needs
to have an S-Video input jack.
The FireWire 800 port is based on IEEE-1394b and uses a 9-pin connector.
