Briefly Explain Different Input and Output Devices of Computer System

Computer devices include input output processing and storage. Previous Post Next Post.

Parts Of A Computer And Input Output Devices

Input and output bridge the chasm between a computers inner world of bits and the real world perceptible to the human senses.

. Input devices provide data input to processor which processes data and generates useful information thats displayed to the user through output devices. It provides man to machine communication. Digitizers Plotters LCD Plasma Display Printers etc.

These devices are called Input devices. Input devices are the component of the computer system that accepts incoming data and instructions and converts them into a pattern of electrical signals in binary code that is understandable to a digital computer. Computer systems consist of three components as shown in below image.

Familiar examples include the mouse which senses movement across a surface and the keyboard which detects a contact closure when the user presses a key. Similarly even a mouse can be an input unit for entering directions and commands. An input device is a mouse or a keyboard were you.

This result is called output. Keyboard Mouse JoyStick Light pen Track Ball Scanner Graphic Tablet Microphone Magnetic Ink Card Reader MICR Optical Character Reader OCR Barcode Reader Optical Mark. These devices can be separated into two classes.

Or Input device can read data and convert them to a form that a computer can use. These devices are designed to read information into or out of the memory unit upon command from the CPU and are considered to be the part of computer. Hence translating into image word sound and action that people understand into a form that the System Unit can understand and process.

Now let start with the input devices Table of Contents 1INPUT Devices a. Output Device can produce the final product of machine processing into a form usable by humans. For example a laptops keyboard is an input unit that enters numbers and characters.

Input Devices of a Computer Keyboard Audio Other Types of Computer Input Devices Computer Output Devices. We enter the information using an input device the processing units convert it into computer understandable languages and then the final output is received by a human-understandable language. COMPUTER INPUT DEVICES Computer Input is the collection of raw datafacts.

The functioning of a computer system is based on the combined usage of both input and output devices. The Output Devices of Computer System are electromagnetic devices or gadgets that accept or acknowledge data or information from the computer system and translate and convert the data in the human-readable or intelligent form. 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.

The computer consists of INPUT and OUTPUT devices which are also known as IO devices. OUTPUT Devices a Monitor. IO device is a piece of a hardware device which is used by humans to communicate with the computer.

Hence the above are examples of input devices output devices and both input and output devices IO devices. Output device is electronic equipment connected to a computer and used to transfer data out of the computer in the form of text images sounds or print. The devices which are used to input the data and the programs in the computer are known as Input Devices.

Digitizer is an input device which converts analog information into a digital form. The main function of input devices is to direct commands and data into computers. Input devices Various hardware devices have been developed to enable the user to interact in the more natural manner.

Some of the Commonly used input units used in a computer system are as follows. Other inputs and output devices are CD and DVD drive multifunctional printer modem digital camera etc. In this article we shall discuss the various input and output devices which can be connected to a computer along with their.

They are Locators and Selectors. An output device is something you can see or hear like the monitor or the speakers. Output devices are the component of computer system that converts the digitized signals into a form.

Input or output devices that are connected to computer are called peripheral devices. Using an input device we can give instructions to the computer to perform an action and the device reverts to our action through an output device. Output Unit When we command a computer to perform a task it reverts for the action performed and gives us a result.

Central Processing Unit Input devices and Output devices. Similarly computer after processing gives output through other devices called output devices. Input devices only allow for input of data to a computer and output devices only.

Generations of Computer 1st to 5th Explained with Pictures. The document has moved here. An input device sends information to a computer system for processing and an output device reproduces or displays the results of that processing.

Monitors Speakers Printers. This is stored in computers memory. Computers then use their CPU to process this data and produce output.

A joystick has two potentiometers they have been attached to. Examples of output devices include. Input to computers consists of sensed information about the physical environment.

Generally the output can be obtained and acquire mainly in two distinct and different ways Softcopy and Hardcopy. When you work with the computer you feed your data and instructions through some devices to the computer.
