- 3. Output devices are pieces of computer hardware that allow a computer system to communicate information to a user or another system. This information can be in any form, and includes sound, images, and even tactile experiences. Output devices can usually only be used to send data from the computer; items called input devices allow users and other systems to send data to the computer. HOME PAGE
- 5. CATEGORIES OF OUTPUT DEVICES A hard copy is a type of material suitable for direct use, meaning that the user can read the material directly, rather than having to process it through a computer or some other technology. The most classic example is printed material on paper. Many industries that work heavily with electronics use the term, along with Continues... HOME PAGE

- 8. THE MONITOR A monitor is also called video display terminal (VDT). The users can view the visual display of the processed data on the monitor. Computer monitors come in a variety of screen sizes and not to forget, visual resolutions. All monitors have a video card, which processes the data into images, to be eventually displayed. Continues…. TYPES OF OUTPUT HOME PAGE
- 9. Continues Cathode Ray Tube (CRT) and flat panel displays are the two types of monitors. CRTs are cheaper, and have good viewing angle. They are also bulkier and consume more power. On the other hand, the flat panel displays have no magnetic interference and lighter. They are also costlier. HOME TYPES OF OUTPUT PAGE
- 10. PRINTER Printer is an external hardware device, which takes processed data from the computer to generate a hard copy of the same. After the monitors, printers are the most used peripherals of computers and they are commonly used to print text data, images, etc. There are three main types of computer printers, namely inkjet, laser and Continues….

The inkjet printer uses magnetized plates that spray ink on the paper to produce the data. On the other hand, laser printers use a laser beam to produce the data. TYPES OF OUTPUT HOME PAGE
- 12. SPEAKER A speaker is a hardware device, that is connected to a computer's sound card, which outputs the sound generated by the card. Audio data generated by the computer is sent to the audio card that is located in the expansion slot. The card translates the data into audio signals, which are then sent to Continues… TYPES OF OUTPUT HOME PAGE
