Output Devices
Output Devices when the CPU processes the results, the result must regularly be produced. A standard output screen is a computer monitor, which lights up thousands of pixels in various colors, which displays text, pictures, and user interface features. Any major output devices in a computer have mentioned below.
- Monitors
- Graphic Plotter
- Printer
Monitors Output Devices
The primary Output Devices of a computer have monitored, generally known as Digital Display Unit (VDU). It creates pictures from small dots, called circular pixels. It is image quality differs on how many pixels.
There are two types of monitors.
- Cathode-Ray Tube (CRT)
- Flat-Panel Display
Cathode-Ray Tube (CRT) Monitor
The CRT display consists of small pixel-like image elements. The smaller the pixels, the clearer or clearer the picture. It requires a number of pixels, like the letter ‘E’s in the word aid, to shape a whole character.
The screen will represent a limited number of characters at the same time. The screen may have broken down into a number of character boxes – a set position on the screen that allows a normal character. Most displays can display physically 80 data characters and vertically 25 lines.
There are some disadvantages of CRT −
- Large in Size
- High power consumption
Flat-Panel Display Monitor
The flat panel monitor is a video class with a lower volume, weight, and power demand than the CRT. They have hung on walls or put on your wrists. Current applications of flat showers include calculators, video games, screens, mobile laptops, and displays of graphics.
Printers Output Devices
Printer is an output system for printing paper material.
There are two types of printers −
- Impact Printers
- Non-Impact Printers
Impact Printers
The impact printers print the characters by clicking them on the wire, loaded into the paper afterwards.
Impact Printer characteristics are as follows
Quite a low cost of use
Very channel bottom
It is useful for bulk printing because cheap.
Physical contact with the paper is available to create a picture
These printers are of two types −
- Character printers
- Line printers
Non-impact Printers
Print characters without using the circle without an effect scanner. The printers print a whole page at a time and have often referred to as Page Printers.
These printers are of two types −
- Laser Printers
- Inkjet Printers
