LCD/Flat panel monitors-
LCD is Short for liquid crystal display. LCD technology can be found in computer monitors. LCD displayer is the monitor; the main purpose of a monitor in a computer system is to show text and graphics, which are generated by the computer. The LCD monitor is connected by a cable. One side of the cable is plugged into the back of the monitor and the other side of the cable is plugged into the hard drive cable port.

Keyboard- In computing, a keyboard is a board that has alphabetical, numerals keys and special purpose keys printed on the membrane layer of the keyboard, the keyboard act as mechanical levers or electronic switches. When you press a button on the keyboard it compresses an electrical switch which activates an electrical circuit, this generates a keystroke signal, processed by the keyboard’s processing chip. The chip processes the key stroke into a scan code. The scan code is transferred to the computer, which then processes the scan code into either part of a system.

Mouse- In computing, a mouse is a inform device that detects two-dimensional motion relative to a surface. This motion is often translated into the motion of a pointer on the monitor or screen that permits for fine management of a graphical computer program. The mouse is used for selecting and activating which makes the activities easier the mouse just makes it much simpler and easier to operate the systems and programs on the computer. The left mouse button is for the selection of and interaction with programs, Internet Web pages and other computer roles. By clicking this button twice, or “double-clicking," the mouse instructs the computer to open the program. The mouse's right button is used for accessing specialized, context-sensitive menu selections for the particular program or screen on which you click it. This allows you quick access to several actions without having to search for them in the toolbar at the top of the screen. The scrolling wheel is basically for you to move the screen up and down real quickly.

Central Processing unit (CPU)
it is the hardware within a computer that carries out the instructions of a computer program by performing the basic logical and input/output operations of the system. CPU does athematic and logical operation with control functions. The CPU is inside the motherboard at the central processing unit.

A cable is a cord, connecter or a plug for a computer. A cable is one or more wires that connect a computer to a power source or computer in this case. The cables have different port connecters that are than connected to the hard drive.

Plasma displays should not be confused with liquid crystal displays (LCDs), another lightweight flat-screen display using very different technology. LCDs may use one or two large fluorescent lamps as a backlight source, but the different colors are controlled by LCD units, which in effect behave as gates that allow or block the passage of light from the backlight to red, green, or blue paint on the front of the

CRT Monitors vs. LCD Monitors

1342 words - 5 pages dramatically different. For starters, LCDs don’t emit their own light, they reflect it. Therefore, LCD screens contain a backlight which provides light to be reflected through the pixels. After the light is reflected off the back of the display, it passes through a pane of polarized glass, then through a liquid crystal substance, and then another pane of polarized glass. A series of electrodes create a “grid” across the whole screen. When two
