ANSWER ALL QUESTIONS

  1. Six Generations of Computers:
    • First Generation (1940-1956): Vacuum tube technology, large and unreliable.
    • Second Generation (1956-1963): Transistors replaced vacuum tubes, smaller and more reliable.
    • Third Generation (1964-1971): Integrated circuits introduced, smaller and faster computers.
    • Fourth Generation (1971-1980): Microprocessors enabled personal computers.
    • Fifth Generation (1980-Present): Artificial Intelligence and parallel processing.
    • Sixth Generation (Future): Predicted advancements in AI, nanotechnology, and quantum computing.
  2. Definition of Input Devices: Input devices are hardware components that allow users to enter data and instructions into a computer. These devices facilitate communication between the user and the computer system.
  3. Nine Examples of Input Devices:
      1. Keyboard: Used to input text and commands.
      1. Mouse: Enables pointing and clicking on the screen.
      1. Scanner: Converts physical documents into digital form.
      1. Joystick: Commonly used in gaming for directional control.
      1. Microphone: Captures and inputs audio data.
      1. Webcam: Captures video input for communication or recording.
      1. Touchscreen: Allows users to interact directly with the display.
