Input devices are the devices that are used to send signals to the computer for performing tasks. The receiver at the end is the CPU (Central Processing Unit), which works to send signals to the output devices. Some of the classifications of Input devices are: Keyboard Devices Pointing Devices Composite Devices Game Controller Visual Devices The most common input devices are the keyboard, mouse, and touch screen. There are hundreds of other input devices, like microphones to capture sound waves, scanners to capture image data, and virtual reality devices to capture our body movements.

What They Do: Input devices allow you to send information to the computer. Examples: Keyboard, Mouse, Microphone, Touchscreen, Scanner These are the tools you use to tell the computer what to do. What are Input Devices in Computer? Computer input devices are hardware instruments for entering data into a computer. The Central Processing Unit (CPU) receives the input from these devices, processes it, and provides an output accordingly (e.g., via monitors or printers). The devices we use are called input devices and include keyboards, touch screens, microphones, movement sensors and webcams. Some examples of input include: Words written using a. keyboard. close. All Pointing Device -is a input device which is used to move cursor position in a monitor screen Like:- Mouse, Joystick, Trackball, Graphics Tablet, Digitizer, Touchpad, Light Pen, Pointing Stick, Touch Screen Remot Control Electronic White Board Scanner OMR (Optical Mark Recognition) OCR ( Optical Ink Character Reader)

A common computer input device, a keyboard. A user presses a key which transfers information to a computer. In computing, an input device is a piece of equipment used to provide data and control signals to an information processing system, such as a computer or information appliance. Examples of input devices include keyboards, computer mice, scanners, cameras, joysticks, and microphones. Input Device Definition: A piece of equipment/hardware which helps us enter data into a computer is called an input device. For example keyboard, mouse, etc. What are The Examples of Computer Input Devices? 1. Keyboard The keyboard is one of the primary input devices for computers. It allows users to input text, commands, and other data into the computer. Keyboards come in various layouts and designs, with the QWERTY layout being the most commonly used. An input/output (I/O) device is any hardware used by a human operator or other systems to communicate with a computer. As the name suggests, input/output devices are capable of sending data (output) to a computer and receiving data from a computer (input). Input devices allow users to interact with a computer by providing data or commands.

Following are some of the important input devices which are used in a computer − Keyboard Mouse Joy Stick Light pen Track Ball Scanner Graphic Tablet Microphone Magnetic Ink Card Reader (MICR) Optical Character Reader (OCR) Bar Code Reader Optical Mark Reader (OMR) Keyboard 1. Keyboard - The keyboard one of the most prominent input devices of the computer, looks similar to typewriters. The keyboard is designed to input data in the format of the text, numbers, and special characters. The computer keyboard is one of the actual examples of input devices in computing. The keyboard is probably the primary means of.
Input is any data that is sent to the computer for processing. Output is the result of processed data that we can see through some other devices. Input devices are controlled by the users. Output devices are controlled by computers. Mouse, Keyboards etc., are input device examples. Monitors, Printers etc., are examples of output devices. Computer input and output devices A computer is an electronic device that works under instructions given by the user to accept, process and output information as required. A computer has two types of devices which help the user to enter data into the computer and allows the computer to display result of the processed data as required by the user.
Difference between Input and Output devices
Input devices provide us a way to give input or instruct the computer to perform a function. It can be any information or data given to the processor and this processor gives the output by some output device. In a computer, the keyboard and mouse are input devices, CPU is the processor and monitor is the output device. Let us read ahead to know more about the various input devices in computers. Input Devices can be defined as an electro-mechanical device that allows a user to input the data into a computer, by usually typing on a keyboard, or by clicking a mouse, we input data into the Computer. The data is processed into the main memory through the input device.
