GRAPHICS CARDS
Colors (4 to 32 bits)
- old: 16 = 2^4 ; 256 = 2^8
- new: 32 K = 2^15; 64 K = 2^16; 16 million = 2^24; 4 billion = 2^32
Resolution (pixels)
- 800 x 600 = 480,000
- 1024 x 768 = 786,432
- 1280 x 768 = 984,040
- 1280 x 1024 = 1,310,720
Video memory (examples)
- 800 x 600, 256 colors = 480,000 x 8 / 8 /1024 = 469 K
- 1,024 x 768, 64K colors = 786,432 x 16 / 8 /1024 = 1.54 MB
- 1,280 x 1024, 4 billion = 1,310,720 x 32 / 8 /1024 = 5.1 MB
