Difference between Input and Output DevicesIn this section we will learn about the input and output devices which are used to operate computer. The computer is a machine which takes input in the user understandable form, convert it to binary and then process it. The result of the processing is the output. Computer has lot many types of input and output. The common examples are:
- Joystick (to play games);
- Miscellaneous Input devices, like camera, pen or flash drives, etc.;
- Speakers (or audio output devices);
Another type of input device is mouse. A typical computer mouse has three buttons. These three buttons are associated with different commands and user can interact with the digital object by using the mouse and one or more of its buttons. The mouse gives user complete freedom to roam on the screen and do anything conveniently, which is not possible with the keyboard.
The output device like speaker is used to output the sound which is available in the computer in the form of songs or music. The songs as well as music is also stored in the form of binary in the computer and when it is played the binary is converted to the voltage which generates particular frequencies and enable us to enjoy the song or the music.
