How Do I Input Data and Output and Store Information? - Lesson 3 3 Input and Output Devices Input devices enable a user to input data and  commands to the computer to be processed. Output devices enable the computer to give or  show you the results of its processing. Some devices can perform both input and  output operations. This lesson covers the most common types of  input and output devices.

How Do I Input Data and Output and Store Information? - Lesson 3 4 Input Devices – The Keyboard The keyboard is the most common input device. As you press keys on the keyboard, an electrical  signal representing that key is sent to the computer. Keyboards are divided into sections: Typewriter keys: The standard alphabetic and numeric  characters you would find on a typewriter. Function keys: Special keys that perform some specific  function for the application being run. Numeric keypad: Used for mathematical operations. Directional keys: Used to move the cursor around the  screen.

How Do I Input Data and Output and Store Information? - Lesson 3 6 Input Devices – The Mouse The mouse is a pointing device that rolls around on a flat  surface and controls the location of the pointer on the  screen. The mouse performs the following functions: Pointing: Place the on-screen pointer at a specific place. Clicking: Press and release the mouse button. Dragging: Holding down the mouse button and dragging an object  to a new location by dragging the mouse. Double-clicking: Pressing and releasing the mouse button twice  very quickly. Right-clicking: Pressing the right mouse button.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
