What is Monitor:- A monitor, also known as a computer display, is an electronic device that displays video and graphics output from a computer. It is the primary visual interface between a computer and its user, allowing them to interact with the system by displaying images, text, and video.
The monitor receives video signals from the computer’s graphics card and displays them on a flat panel screen. Monitors can be either cathode-ray tube (CRT) or liquid crystal display (LCD) based. CRT monitors use a large glass tube that produces images by directing an electron beam onto a phosphorescent surface. LCD monitors, on the other hand, use a thin layer of liquid crystal material that can change its optical properties in response to an electric current, creating images on the screen.
Monitors come in different sizes and resolutions, with larger screens and higher resolutions allowing for more detailed and clearer images. They are essential components of most modern computer systems and are used in a variety of settings, including offices, homes, and classrooms.
Today in this article I am going to tell you what is monitor and various types of monitor. So let’s get started…
