                  THE PERIPHERALS
the word peripherals means things placed around any device when we talk about the computer, technically we talk about the system unit or CPU rest of the parts which are put around the computer and connector and connected to it are known as peripherals.
there are numbers of peripherals used with the computers. so we should know about some of the important peripherals.
KEYBOARD:
                        the keyboard is a very essential peripheral to work with the computer. it is used to enter words and numbers into the computer just like typing on an electronic typewriter. all the available keyboards are similar in function but the layout can be different hence they can hold 101, 102, 104, 105, 106 or 108 keys.
MOUSE:
                  Mouse is a pointing device. it looks like a small soap case and has a cable that looks like the tail of a mouse. it does not looks like a mouse but it is called a mouse due to its quick movement on the screen. a tilt arrow represents the mouse on the screen which is known as pointer.

when you skip (drag) the mouse on the mouse pad, the pointer moves on the screen accordingly.this is after placing the pointer on any option. you can press the click button of the mouse which will work as you have typed the command on the keyboard and press the Enter key.
MONITOR:
                      the monitor, which looks like a portable television, is the main output device of the computer. it keeps an eye on each and every movement happening in the computer and displays them on the screen. all the inputs and outputs can be seen on the monitor screen. Moreover the message given by the computer can be seen which helps us in correcting mistakes.

all the modern monitors are based on VGA (Video Graphic Array) technology that provides very good quality of display. your monitor is mono chrome (black and white) or color, it must be controlled with VGA card installed in your CPU. Otherwise you will not be able to run the latest software.
