Chapter # 13 ( Monitor OR Display )

You might know about TV (television), monitor is also like TV in its design and shape but, its functions are a little but more than a TV. Whatever we try to find out on computer, it shows the result on the screen of monitor in the form of written or pictures.

Similarly, when we compose English, Urdu or Arabic or any other language on computer, the computer shows the result on the the screen of monitor. There is a button on screen which is used for the purpose of ON-OFF. Monitor also contains some other buttons which are useful in setting of colors and appearances of monitor. Composing of any type can easily be read on screen and you can also increase/decrease its size.

The main source of interacting between you and computer is definitely the monitor. You can operate a computer without interfacing, without disk drives or without different cards but can't without a monitor. Operating a computer without a monitor is just like finding a black in a dark room.

In birth days of computer, the computers were only in the form of some boxes and there were no any concept of monitor at that time. Users of that time computer correct their records according to some specific lights and after printing they find out their mistakes.

In those days, all of working of computers was just like a type writer. When CTR Terminal Tube or Monitor was introduced then it increases the value and importance as well as efficiency of computers. After that invention, it seemed to be the necessary part of of the computer since that time.

Any computer video system consists of following two big things.

  1. Monitor OR Display
  2. Video Card

Monitor needs a input unit which can provide actions and guild lines. In some computers this function is controlled by mother boards. On the other hand video adapter, video cards and graphic cards also being connected with computers now a days.

Today, color monitors are also available in the market which can display 250 to 1000 different colors. Actually these colors are connected with three different phosphorus and then display colors. Basically there are three colors Red, Green and Blue. These colors are due to signals which send to electroguns and then electroguns send any one of those basic colors to screen (monitor). Those colors transfers in the form of waves from metal conductor and that conductor is known as Sheeto-Mask.

Color monitor is more comfortable as compared to simple black and white monitors. Composing of any type as pictures can also seen on screen of monitor such as people, building, animals and any type of other pictures, movies or games.

Just think a while, if there wouldn't be any monitors available in the world that it might possible that there will definitely a value of computers but it can be said there will be a decrease in interest of people to the computer and that will lead to decrease importance of computer in the world. Therefore, it can be said that a computer is an incomplete without a monitor.
