Input and Output Devices for SSC CGL Tier 2 Preparation

Input and output devices are the essential parts of a computer system. They allow the user to interact with the machine by sending data in and receiving results out. In SSC CGL Tier 2, questions are often asked about the examples, functions, and differences between input and output devices.

What are Input and Output Devices?

Input devices give information to the computer, while output devices show you the results. Together, they allow the computer to interact with users and perform tasks efficiently.

TypeFunctionExamples
Input DevicesSend data or instructions to a computerKeyboard, Mouse, Scanner
Output DevicesDisplay or produce the processed results from a computerMonitor, Printer, Speakers

Examples of Input and Output Devices

Input and output devices are essential hardware components that allow a computer to interact with the user. Input devices help feed data and instructions into the computer, while output devices display or produce the results of the processed data. Understanding these devices is important for SSC CGL Tier 2, as questions often test their functions and examples. Below is a table listing the most common input and output devices with their uses.

Output DevicesMonitor, Printer, Speakers, ProjectorDisplay or produce the processed results from a computer

Difference Between Input and Output Devices

Input and output devices serve opposite but complementary roles in a computer system. While input devices allow users to provide data, output devices let the computer communicate results back to the user.

Flow of Input and Output in a Computer

The working of a computer system can be better understood with the help of a simple flow diagram. First, the user provides data or instructions through an input device. This data is then processed by the computer’s CPU. Finally, the result is sent to an output device, which presents it back to the user in a readable or usable form. This cycle shows how input and output devices work together to make human-computer interaction possible.

Key Takeaways

  • Input devices let you enter data into the computer.
  • Output devices display or produce the results.
  • Important to know examples and differences for SSC CGL Tier 2.
  • Some devices like touchscreens can act as both input and output.
