A soft copy is an electronic copy of a document. It contrasts with a hard copy, a document printed out on paper or another medium. HOME PAGE
  7. 7. Soft copies are easy to transfer, distribute, share, and manipulate all potential drawbacks or advantages, depending on the document involved. HOME PAGE
  8. 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.

  9. 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. 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. 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
