CHAPTER 9: INPUT AND OUTPUT DEVICES

As in computer terminology, I am also going to share you about input and output devices that are related to the computers. First of all, you need to know the concept of these two words, 'input' and 'output'. We need to use some input devices to produce output. If there is no input inserted, no output can be produced. Before computer process our data, we use few method to input data in our machine (computer). The device we use depends on what form of data it takes. After the computer has processed the data, the output could be a display on the computer screen, hard copy on printed pages, or even the audio playback of music we composed on the computer. Here are the lists of input and output devices of a computer :
