Input & Output Devices
by Naima Johnson
1. The terms “input” and “output” are used both as verbs to describe the process of entering or displaying the data, and as nouns referring to the data itself entered into or displayed by the computer.
2. Resources: Lever-Duffy, J. & McDonald, J.B. (2011). Teaching and learning with technology (4the Ed.). Boston, MA: Pearson Education
3. Input Device: Before a computer can process your data, you need some method to input the data into the machine. The device you use will depend on what form this data takes be it text, sound, artwork, etc. Examples: Keyboard, Mouse and Touch Pad.
4. Output Devices: Similarly, after the computer has processed your data, you often need to produce output of the results. This output could be a display on the computer screen, hard copy on printed pages, or even the audio playback of music you composed on the computer. Examples: CRT (Cathode Ray Tube) monitor, Flat Panel Monitor, and Ink Jet Printer.
