Most commonly used input devices are discussed below. Graphics Tablet. A computer has several input device namely, … Plc is easy to use which provides a lot of features to users like fix inputs and outputs it also has discrete input and output capability.

An input device sends information to a computer system for processing , and an output device reproduces or displays the results of that processing. Input devices only allow for input of data to a computer and output devices only receive the output of data from another device. Most devices are only input devices or output devices, as they can only accept data input from a user or output data generated by a computer. For example, as shown in the top half of the image, a keyboard sends electrical signals, which are received as input. Those signals are then interpreted by the computer and displayed, or output , on the monitor as text or images. In the lower half of the image, the computer sends, or outputs , data to a printer. Then, that data is printed onto a piece of paper, which is also considered output.

Chapter 9: Input-Output Devices

In this lesson students consider a number of computing devices to determine what types of inputs and outputs they use. Groups are assigned to a computing device and based on a teacher-provided definition of input and output, list the inputs and outputs of their device. Earlier in the activity students are prompted to focus on more obvious physical inputs and outputs e. Throughout the lesson the teacher records inputs and outputs that are identified on a T-Chart at the front of the room. To conclude the lesson students examine common activities they do on a computing device and select the inputs and outputs used for that activity from the chart. In the previous lesson students were introduced to the input, output, store, and process model of a computer.

Output Device can produce the final product of machine processing into a form usable by humans. It provides man to machine communication. Keyboard is most common input device is used today. The data and instructions are input by typing on the keyboard. The message typed on the keyboard reaches the memory unit of a computer.
