Answer: Option B. -> Audio output
Soft copy refers to digital information that is stored on an electronic device and can be accessed through a screen or display. There are two types of soft copies: data output and audio output.
Data output refers to digital information that is presented visually, such as text, graphics, or images. This can be displayed on a screen or printed on paper using a printer.
Audio output, on the other hand, refers to digital information that is presented as sound. This can include music, speech, or other audio recordings.
Some common examples of audio output include:
  • Music played through speakers or headphones
  • Sound effects in movies or video games
  • Voice recordings or phone calls
Audio output is typically produced through a device such as a speaker or headphones, which convert digital signals into sound waves that can be heard by the listener. The quality of the audio output can be affected by a number of factors, such as the quality of the digital signal, the performance of the audio device, and the acoustics of the environment in which the sound is being produced.
In summary, audio output is the second type of soft copy, which refers to digital information that is presented as sound. It is an important component of many digital devices and applications, and is used for a wide range of purposes, from entertainment to communication.
Some key points to remember:
  • Soft copy refers to digital information that is stored on an electronic device and can be accessed through a screen or display.
  • There are two types of soft copies: data output and audio output.
  • Audio output refers to digital information that is presented as sound.
  • Audio output is typically produced through a device such as a speaker or headphones.
  • The quality of the audio output can be affected by a number of factors.

  2.    Speech recognition
  3.    Data coding
  4.    Printing
  5.    None of these
 Discuss Question
Answer: Option A. -> Monitor
Monitor, provides a visual display of data. A monitor is an electronic display that can display images and text generated by a computer. It is also known as a computer screen or a visual display unit (VDU). In this answer, we will discuss the different types of monitors, how they work, and their applications.
Types of Monitors:
  1. Cathode Ray Tube (CRT) Monitors: These monitors were the first type of computer monitors, which use a large vacuum tube to display images. They are bulky and consume more power than modern monitors.
  2. Liquid Crystal Display (LCD) Monitors: These monitors use liquid crystal cells to display images. They are thinner, lighter, and consume less power than CRT monitors.
  3. Light Emitting Diode (LED) Monitors: These monitors use light emitting diodes (LEDs) to display images. They are similar to LCD monitors but have a better contrast ratio and consume less power.
How Monitors Work:A monitor receives digital signals from the computer and converts them into visible images. The digital signals are converted into analog signals, which are then sent to the monitor's display controller. The display controller converts the analog signals into the appropriate voltage levels that activate the monitor's pixels. The pixels create the images by emitting light of different colors.
Applications of Monitors:
  1. Computer Displays: Monitors are commonly used to display images and text generated by a computer.
  2. Television: Monitors can be used as a television display when connected to a TV tuner or set-top box.
  3. Video Games: Monitors are also used as a display for video games.
  4. Security Systems: Monitors are used in security systems to display images from security cameras.
In conclusion, Option A, Monitor, provides a visual display of data. Monitors come in different types, such as CRT, LCD, and LED monitors, and they work by receiving digital signals from a computer and converting them into visible images. Monitors have various applications, such as computer displays, televisions, video games, and security systems.
Question 9.

Drum printer is an example of

  1.    input
  2.    output
  3.    processing
  4.    storage
  5.    None of these
 Discuss Question
Answer: Option B. -> output
An output device is a peripheral device used to display or print processed data from a computer. The output can be in the form of text, graphics, images, or sound.
Drum printers are one of the earliest types of computer printers and were widely used in the 1960s and 1970s. They consist of a metal or plastic drum with characters engraved on the surface. The drum is rotated at high speed, and the characters are struck by a print hammer to produce an impression on the paper.
Here are some characteristics of drum printers:
  • High speed: Drum printers are capable of printing at high speeds and can produce several hundred lines per minute.
  • High-quality text: Drum printers are capable of producing high-quality text with good contrast and sharpness.
  • Noisy: Drum printers are relatively noisy compared to other types of printers. The print hammer strikes the paper with considerable force, producing a loud noise.
  • Limited graphics capability: Drum printers are not suitable for printing graphics or images. They are primarily used for printing text.
In summary, drum printers are an example of output devices used to produce printed output from a computer. They are fast and capable of producing high-quality text but are noisy and not suitable for printing graphics or images. Other examples of output devices include printers, displays, speakers, and projectors.
