Input And Hard Copy Devices

Input devices and hard copy devices are important components of computer graphics systems. Input devices allow users to create and manipulate digital images, while hard copy devices produce physical copies of those images.

Input devices include:

1. Keyboard and Mouse: The most common input devices used in computer graphics. The keyboard is used for typing and entering commands, while the mouse is used for pointing and clicking on screen elements.

2. Graphics Tablet: A specialized input device that allows users to draw and manipulate digital images using a stylus or pen. Graphics tablets are particularly popular among digital artists and designers.

3. Touchscreen: A display that can detect the presence and location of a touch on its surface. Touchscreens are commonly used in tablet computers, smartphones, and other mobile devices.

4. Scanner: A device that captures images or documents and converts them into digital format. Scanners are commonly used for digitizing photographs and other artwork.

Hard copy devices include:

1. Printer: A device that produces physical copies of digital images and documents. Printers come in a variety of types, including inkjet, laser, and thermal printers.

2. Plotter: A specialized printer that produces large-scale prints, typically used for engineering drawings, architectural plans, and other technical illustrations.

3. Photographic Printer: A device that produces photographic prints from digital images. Photographic printers are commonly used in the photography and printing industries.

4. 3D Printer: A device that produces three-dimensional objects from digital models. 3D printers are increasingly being used in manufacturing, product design, and other applications.

Overall, input devices and hard copy devices are essential components of computer graphics systems, allowing users to create, manipulate, and share digital images in a variety of formats.
