SUMMARY 38 •“The keypad are point-and-draw devices. They are used to rapidly point to and select a graphic icon or menu item from multiple options displayed on the GUI of a screen. • The I/O i.e. the input/output devices provide a means of communication between the computer and the outer world. They are often referred to as the peripheral devices sometimes. •The input devices are used to enter data from the outside world into primary storage. The output devices supply results of processing from primary storage to users. •The input is given to the input device, then the data in coded in internal form and is sent to the CPU. Further, the processed data is sent to the output device and the result is obtained. •GUI stands for a graphical user interface. Graphical user interface basically provides a set of graphical elements on the screen to the users. Commonly used for point-and-draw devices. •OMR stands for optical mark reader. These are very useful for grading tests with objective type questions or for any input data that is of choice or selection nature.” www.cuidol.in Unit-4,5,6(BCM104/BBA104/BTT104/BAQ102) All right are reserved with CU-IDOL

FREQUENTLY ASKED QUESTION 39 Question1: Why does a computer need both input and output devices? Answer: 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 Question2: Which output device is used for producing highly accurate very large drawings and poster? Answer: A plotter can be used to produce high quality, accurate, A3 size or bigger drawings. They are usually used for Computer Aided Design (CAD) and Computer Aided Manufacture (CAM) applications , such as printing out plans for houses or car parts. Question3: What are the different forms of output? Answer: There are four different categories of output device: visual, data, print, and sound. Question4: What is output device give examples? Answer: Speaker - A speaker gives you sound output from your computer. ... Monitor - A monitor is the screen on which words, numbers, and graphics can be seem. Printer - A printer prints whatever is on the monitor onto paper. Headphones - Headphones give sound output from the computer. www.cuidol.in Unit-4,5,6(BCM104/BBA104/BTT104/BAQ102) All right are reserved with CU-IDOL
