input and output devices

Therefore, light pens are used to select and draw objects. Any graphics made with a light pen can be stored on the computer and can be edit again when needed. The concept of input and output devices is much simpler than it sounds. I/O devices widely used in specialized simulations. The keyboard is designed to input data in the format of the text, numbers, and special characters.

The use of trackballs became very common in computers to use in video games and for graphic designing applications. It is similar to a printer but has more advanced features with more accurate, faster with high-resolution graphics. Input hardware serves to send data into the computer's CPU, while output devices send data outwards to the user. From the above you know the Input and output devices separately. Mouse – The mouse is another input device of a computer, also known as a pointing and Cursor Moving Device. The microphone is used as a.
