In computing, input/output or I/O is the communication between an information processing system, such as a computer, and the outside world, possibly a human or another information processing system. Output devices convert data from the computer to an externally acceptable form. Uses: Displaying output in the way human can understand. Mcq on input and output devices of computer | Computer input output devices questions and answers in Hindi ”are published. Any input that a computer receives must be digitised. Objective questions related to computer input and output devices | Mcq on input and output devices of computer. The computer user sends manipulations through input devices, which enter the motherboard and processor, ultimately manifesting themselves in the operating system. Also, the drive sends data contained on a CD or DVD (output) to a computer. 2. For example, the speakers of a multimedia computer system are directly connected to a device controller called an audio card (such as a Soundblaster), which in turn is connected to the rest of the system. Let’s go through the Examples. It is an Input device in a way that when the user presses the screen, information is sent to the CPU so that it can be processed. 84% average accuracy.

Interaction of Input and Output Device Share practice link. No Audio Input or Output Devices found After latest windows 10 update no audio devices are listed/ Looking in device manager - the audio devices all say working OK. in which the image or video is recorded(inputted) and stored in digital form in memory cards. This device works like a Xerox machine. Since the output results are displayed on a large screen by a screen projector, it can be seen by a huge number of people at a single point of time. When a close match is found, the word is recognized. Introduction about Input and Output devices is described by Computer Courses in Chandigarh at sector 34A. 6. (6) Optical Character Rader : It’s a device which detects alpha numeric characters printed or written on a paper. Input and Output Devices Before a computer can process your data, you need some method to input the data into the machine. These devices communicate with CPU to receive the inputs from a user and output the results in some form or the other. 2. The audio produced by the speakers is done by a hardware component sound card that pre-installed on the computer. Tip – Read all the 9 Types of Keyboards with pictures as per the needs and comfort. Microphone gives sound or voice input to the computer. Meaning: I/O devices or (both input and output devices) are those devices that have both the functionality at the same time. Practice. The bank's code number and cheque number are printed on the cheques with a special type of ink that contains particles of magnetic material that are machine readable. It is used exclusively in Personal Digital Assistants (PDAs). The monitor is composed to display all the symbolic, text, and graphical information as Soft Copy on its screen. Printer- It is an electronic external output device of the computer. MICR input device is generally used in banks as there are large number of cheques to be processed every day. Fax Machine – The fax machine receives the soft copy document and converts them into hard copy into a series of zeros and ones (also known as bit maps). These devices recognize the movements of the human’s head (. Summary of Input vs. Output Device. Features, Uses, and Difference Between LAN, WAN and MAN. Virtual Reality is the combination of two words ‘virtual’ and ‘reality’. Most of the mouse’s have a ball beneath them, which rotates when the mouse in moved.
