7.Ip Adrress:Internet Protocol Address
-is a numerical label assigned to each device (e.g., computer, printer) participating in a computer network that uses the Internet Protocol for communication.^[1] An IP address serves two principal functions: host or network interface identification and location addressing. Its role has been characterized as follows: "A name indicates what we seek. An address indicates where it is. A route indicates how to get there."^{[2]
8.LCD:Liquid Crystal Display
-}s a thin, flat electronic visual display that uses the light modulating properties of liquid crystals (LCs).LCDs are more energy efficient and offer safer disposal than CRTs. Its low electrical power consumption enables it to be used in battery-powered electronic equipment. It is an electronically-modulated optical device made up of any number of pixels filled with liquid crystals and arrayed in front of a light source (backlight) or reflector to produce images in colour or monochrome. The earliest discovery leading to the development of LCD technology, the discovery of liquid crystals, dates from 1888.^[1] By 2008, worldwide sales of televisions with LCD screens had surpassed the sale of CRT units.
