Hub
There are lots of definitions of hub for its comprehensive applications. In
data communications, a hub is a place of convergence where data arrives
from one or more directions and is forwarded out in one or more other
directions. Networks apply devices called hubs to connect multiple
computers together into a LAN.
I
I Frame
Intra Frame is known as I Frame. It is a video compression method used in
MPEG decoding. An I Frame is coded without reference to other pictures.
Infrared illuminator
A light source operating in the infrared frequency range.
Interlaced
Interlace is one common way of compressing video. As the frames are
projected on the screen, the electron beams alternates between showing
even and odd lines, resulting in the two vertical scans on the screen, with the
field (each set of lines) being updates 60 times a second, and with the frame
(both fields) updated 30 times a second.
IP
IP is the abbreviation of Internet Protocol. This protocol is used for data
transferring between two computers on the Internet. Each computer (known
as a host) on the Internet has at least one IP address that uniquely identifies
it from all others on the Internet.
IP address
This is a numeric address that is then translated into a domain name by the
DNS (domain name server). In the most widely installed level of the
Internet Protocol (IP) today, an IP address is a 32-bit number that identifies
each sender or receiver of information that is sent in packets across the
Internet. When we request a HTML page or send a e-mail, the computer
translates this into its IP address. The TCP/IP protocol then uses it for
routing the data packets to their destinations.
