We would be discussing various types of memories and memory devices in the following pages of this chapter. T hese devices are a vital part of the computer to process throughout the functions of the computer. Input/Output Devices Input/Output devices don’t only produce output, but can also be used as storage and input devices. Data projectors are output devices used to project the digital output from a computer device on to a large screen or wall. Examples of Input Devices. That means a devices which can be used as both input device and output device are called Input / Output (I/O) devices. Input Device is a hardware part of the computer that is used to enter data and instructions into computer memory. The memory serves as the space to store the instructions. It looks like an ordinary camera, but no film is used therein, instead a CCD (changed coupled Divide) Electronic chip in used. Email. With respect to class 3 Input and Output Devices, a keyboard, which looks like a typewriter, is the most common input device of a Computer System. Computer components. USB drives receive or save data from a computer as an input and it can also send data t… When exploring the functions of input devices, looking at the keyboard is important as it is the device people use most to input data. Common devices for Input and Output Device; Most often used input devices are the keyboard, mouse, webcam, scanner and microphone. How Do Input and Output Devices Work? In fact, its history … Created by Pamela Fox. The message typed on the keyboard reaches the memory unit of a computer. There are software and hardware in a computer. For additional information and examples, see our input device page. Input and output devices are the basic components of a computer system. About Us |  Contact Us |  FAQ Dinesh Thakur is a Technology Columinist and founder of Computer Notes.Copyright © 2021. With a keyboard, it is possible to input text and numbers, as well as execute a number of actions, such as printing, taking a screenshot or moving around a Web page. The difference between input and output devices is that input devices are used to send data into the computer while output devices are used to take data out of the computer. Without output devices, we will have to understand binary numbers, which is a very hard thing. The designation of a device as either input or output depends on perspective. The user can usually choose whether the projector mirrors their computer screen, extends it, or replaces it. components of computer INPUT AND OUTPUT DEVICES Input Devices A hardware component used to enter data and instruction into computer is called input device. (9) Plotter : Plotter is an O/P device that is used to produce graphical O/P on papers. Because I/O device data is bi-directional, such devices are usually categorized under storage or communications. Keyboards have the combination of letters and numeric keys. When light falls, on the chip though the lens, it converts light waves into electrical waves. For additional information and examples, see our input/output page. An input/output device can receive data from users, or another device (input), and send data to another device (output). Keyboard: King of the input devices – the keyboard is no stranger to most people. The devices which are used to input the data and the programs in the computer are known as “Input Devices“. The devices which are used to input the data and the programs in the computer are known as “Input Devices“. Then, that data is printed onto a piece of paper, which is also considered output. Most personal computers have a mouse and keyboard, but laptop systems typically use a touchpad instead of a mouse. Examples of Output Devices [edit | edit source] Output devices come in many forms, depending on the information that it needs to show. It’s touched to the CRT screen where it can detect raster on the screen as it passes. The user spins the ball in various directions to effect the screen movements. Output devices serve to read some data from a computer. Input and Output Devices – Sample Questions. It provides man to machine communication. One of the main differences between input and output devices is that input devices are ones that are used to give input to the system by the users, whereas output devices are those, which are used to reproduce the output signals for the user. 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. While the devices whose main function is to give instructions and data to the computer are called input devices. Learn faster with spaced repetition. Input & output devices. It can be either internal or external, though we more commonly think of external devices when talking about peripherals. The mouse is rolled over the mouse pad, which in turn controls the movement of the cursor in the screen. An input device is a piece of hardware used to provide data to a computer used for interaction and control. Devices for communication between computers, such as modems and network cards, typically perform both input and output operations. An input/output device is capable of receiving data from users or another devices and also sending data to another devices or computers. Output devices give the computer the ability to provide us with necessary information. They receive input from the user and send the output to other devices. There are many input and output devices of the computer. Using an input device we can give instructions to the computer to perform and action and the device reverts back to our action through an output device. So a LAN card could be considered i/o, a scsi card could not. The signal pattern is then transmitted to a computer when it’s compared to a dictionary of patterns that have been previously placed in a storage unit of computer. We can click, double click or drag the mouse. Projectors are ideal when training or presenting information to a large audience. (3) Scanner : Scanners are used to enter information directly in to the computers memory. An output device can receive data from another device and generate output with that data, but it cannot send data to another device. Light pen is a pointing device similar to a pen. Keyboard is most common input device is used today. The computer transmits data to the drive, where it is saved and can be later accessed. This is also called a digitizing tablet. C Program input/output of an array with the help of a for loop.

An input device sends information to a computing system for processing, and an output device reproduces or displays the results of that processing. They are directly connected to an electronic module inside the systems unit called a device controller. (10) Digital Camera : It converts graphics directly into digital form. They are directly connected to an electronic module inside the systems unit called a device controller . (8) Voice Input Systems : This devices converts spoken words to M/C language form. If the output device is busy in producing an output, the other outputs are queued up in the memory. An I/O device is a device with both functionalities. During the first two decades of commercial use of computers, 110 operation was performed mostly by punching holes on cards and paper tape with a special device. Here you’ll find … What is the difference between data and information? Similarly, when the CPU processes the inputs to produce outputs, there must be a space where these outputs could be queued up. Output device. Some of the I/O devices are explained below: (1) Keyboard : Keyboard is used in the input phase of a computer-based information system. A device sends information to a computer system for processing, such device is called as an input device and a device that receives and then reproduces or displays the results of that processing is called an output device. Those signals are then interpreted by the computer and displayed, or output, on the monitor as text or images. It has very similar … An input device is something you connect to a computer that sends information into the computer. Unlike a mouse, the device stays stationary whilst the user moves the ball within its socket.
