Although there are higher resolutions available (for example, Super VGA has a resolution of 800 x 600), Standard VGA can display very good images and comes with most new computers. Standard VGA requires a VGA board and a monitor capable of displaying VGA graphics. A Standard VGA board comes with 256K of memory attached to the board. This limits 640 x 480 VGA displays to 16 colors. Both the resolution and the number of colors of display can be increased by increasing the memory on the graphics board. For example, if this memory is increased to 512K, a resolution of 640 x 480 with 256 colors is possible. Similarly, if this memory is increased to 1 MB, resolutions of 800 x 600 or 1024 x 768 with 256 colors are possible. These graphics are called extended graphics. Higher resolutions with more colors make image displays noticeably better. But the computer system must have a monitor capable of displaying such high-resolution images. 6. Laser printers are*most commonly used to output graphics in hard copy form. 7. Plotters are also used to output graphics in hard copy form. Software Requirements for Graphics In addition to the above listed devices, the following graphics processing capabilities are highly desirable ii multimedia computer system for better presentation and use of graphics information: 1. Painting or drawing software.
