Information technology input and output devices

They cannot accept or reproduce information output from the computer. Anything stored is data, but it only becomes information when it is organized and presented meaningfully. Printer This is an important output device of the computer system.

Light Pen Light pen is another pointing type input device. For more information on memory, see memory external storage External storage also called auxillary storage is any storage other than main memory.

It is used for recording sound.

What is the difference between an input and output device?

The user spins the ball with fingers to move the pointer on the screen. Usually the group is a single eight-bit byte or possibly seven or nine bits, with the possibility of various control or parity bits included in the data stream.

These help us put date into the computer. Information ethics The field of information ethics was established by mathematician Norbert Wiener in the s. The mouse is used in windows based programs, where the user can run the commands by pointing the objects with the help of pointer and clicking the buttons on the mouse.

The text which is to be scanned is illuminated by a low frequency light source. It gives a printed output of the results that appears on the monitor screen. The parts of a computer that help us to show the results of processing are called out devices.

The number of pixels that a monitor can show on its screen is referred to as the resolution of the screen.

Basics of computer hardware

Optical mouse uses red light to track the movement of mouse for moving the pointer on the computer screen. Also, the drive sends data to a computer or another device output. Let us find out about some more devices that can be connected to a computer.

It cannot receive and reproduce output sound sent by other devices.

List of Input Devices, Output Devices and Both Input Output devices related to computer.

Our educational games are easy to use and classroom friendly, with a focus on the parts of speech, grammar, Spanish, fractions, multiplication and division, typing, geography, science, strategy, puzzles and much more! The scanner reads the image and saves it in the computer as a file.

A bus is a set group of parallel lines that information data, addresses, instructions, and other information travels on inside a computer.

The device for listening to the recorded sounds without disturbing others. You can save them in the computer. The mouse is rolled over the mouse pad, which in turn controls the movement of the cursor in the screen.

The two commonly used monitor types are: Touchscreen Touchscreen is a special computer screen that takes the input by sensing the touch of a human finger, gloved hand, stylus, pen or any other pointing device.

These help us to show the results of processing. January 5, InformationQ.The devices which are used to input the data and the programs in the computer are known as "Input Devices". or Input device can read data and convert them to a form that a computer can use. Output Device can produce the final product of machine processing into a form usable by humans.

It provides man to machine communication. Some of the I/O devices are explained below. An introduction to Canon technology. Provides an overview of Canon's office multifunction devices technology, with illustrations.

Computer Input and Output Devices

Input and Output Devices: Links to topics on this page: Before a computer can process your data, you need some method to input the data into the machine. The device you use will depend on what form this data takes (be it text, sound, artwork, etc.).

What is the difference between an input and output device?

In computing, input/output or I/O (or, informally, io or IO) is the communication between an information processing system, such as a computer, and the outside world, possibly a human or another information processing system.

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 Input devices are necessary to convert information or data in to a form which can be understood by the computer. A good input device should provide timely, accurate and useful data to the main memory of the computer for processing.
