In a hard disk information is stored on both the surfaces of each disk plate except the upper and the lower surfaces of the bottom plate which are not used. It looks like an ordinary camera, but no film is used therein, instead a CCD changed coupled Divide Electronic chip in used. They are light weighted and flat screen monitors.
Monitors are categorized into two groups: Examples of input devices include the following. They are high speed devices and are often used with mainframes, minicomputers, or networked machines rather than with single user system. To form the image on the screen, an electronic gun sealed inside a large glass tube fires electrons at phosphorous coated screen to light up the appropriate pixels in the appropriate color to display images.
The message typed on the keyboard reaches the memory unit of a computer.
By placing the phosphors directly next to each other, and activating them with different intensities, color monitors can create an unlimited number of colors. Since the whole device is not moved, a track ball requires less space than a mouse.
Microphone Microphone is an input device to input sound that is then stored in a digital form. The microphone is used for various applications such as adding sound to a multimedia presentation or for mixing music. The reflected light is received by the photocells.
Green screen was the common name for a monochrome monitor using a green "P1" phosphor screen. A mouse can be used for many application, ranging from games to drawing and designing products with computer graphics. A variety of input devices are used with the computer depending on the type and purpose of input information.
Plotters have been used in automotive and aircraft design, topological surveys, architectural layouts and other similar complex drafting jobs. Some financial services use voice verification systems to secure telephone banking transactions.
Keyboard is most common input device is used today.
Finally, the electrified charge is removed from the drum and the excess toner is collected. They perform the following functions: Track ball is similar to the upside- down design of the mouse. The user moves the ball directly, while the device itself remains stationary.
Optical mouse uses red light to track the movement of mouse for moving the pointer on the computer screen. The output produced on the screen is called Soft Copy Output because it cannot be retained for a long time.
Engineers and Architects use plotters. Dinesh authors the hugely popular Computer Notes blog. The impact printers print the characters by striking them on the ribbon which is then pressed on the paper.
A keyboard can be used effectively to communicate with the computer but considered to be relatively slow as compared to other input devices. The user spins the ball with fingers to move the pointer on the screen.
For additional information and examples, see our input device page. When the mouse is moved on the mouse pad, a light beam underneath reflect to give motion to the pointer on the screen.
The joystick can be moved in all four directions.10 Examples of Input Devices The computer keyboard is the most widely used device for inputting text into a computer. Most keyboards allow you to enter both text and numeric data and to use designated function keys as shortcuts for common system functions.
Jun 28, · A variety of input devices are used with the computer depending on the type and purpose of input information. For example, a keyboard is commonly used to transfer data or information from human readable form to machine readable form.
So, examples of input and output devices. Well, input device could be anything from a keyboard, text file, network connection - anything where you will be taking input from.
Output can be your screen, a printer, file, again anything where output can be sent to. Output devices allow computers to communicate with users and with other devices. This can include peripherals, which may be used for input/output (I/O) purposes, like network interface cards (NICs), modems, IR ports, RFID systems and wireless networking devices, as well as mechanical output devices, like solenoids, motors and other electromechanical devices.
Keyboard is the most common and very popular input device which helps to input data to the computer.
The layout of the keyboard is like that of traditional typewriter, although there are some additional keys provided for performing additional functions. Keyboards are of two sizes 84 keys or / Examples include: Monitor, printer, plotter, speaker, and multimedia projector.
Different Types of Output Devices 1.
Monitor. LCD Monitor: CTR Monitor Monitor is the most commonly used output device used to display results of processing.
It has a TV like shape. What are Different Types of Input Devices Explain Different Types .Download
