The monitor has millions of phosphorus dots of green, blue, and red colour. Cathode ray tubes use electron guns to produce a beam of electrons that produces electrons by striking on the inner phosphorescent surface of the screen. They are identical to vacuum tubes and images are produced by them in the form of video signals. Some common types of computers are discussed below Monitor is the main output device that displays the processed information or data as images, text, video or audio. It is the screen or display unit of the computer. (1) Impact Printer: In impact printers, characters are printed on the ribbon, which is then smashed on the paper. Or we can say that such type of printer uses a print head or hammer to print the data on the paper.Some of the most popular output devices are discussed below:

Printers are divided into two categories: Or in other words, it is an output device that creates a hard copy of the processed data or information. Printers are information output devices that allow you to print data on paper. It has a good contrast ratio, high refresh rate, etc. The resolution of this monitor is also high up to 1920 x 1920. So when the electricity supply on the gas present in the cell converts into plasma and produces UV light that creates an image. In a plasma monitor, a small cell is present in between two glass surfaces and these cells contain a solution of noble gases and mercury. (3) Plasma Monitor: It is also a flat panel display but it is based on plasma display technology. Calculators, video games, monitors, laptop computers, and graphical displays all use flat-panel displays. They can be put on the wrist or hang on the wall. (2) Display on a Flat Panel Monitor with a Cathode-Ray Tube (CRT): A flat-panel display is a type of video display with less volume, weight, and power consumption than a CRT. Refresh Rate: Total number of times per second that an image on a display is repainted or refreshed.Size: The size of the monitor – The diagonal measurement of a desktop screen is typically 14 to 25 inches.Resolution pixels: Pixels are the smallest element of any image.Difference between 32-bit and 64-bit operating systems.Random Access Memory (RAM) and Read Only Memory (ROM).Difference between Multiprogramming, multitasking, multithreading and multiprocessing.Difference between Multiprocessing and Multithreading.
