Binary Data (again!)
The computer screen on your Win 98 PC can be configured for different resolutions. One resolution is 600 x 800 x 8, which means that you have 600 dots vertically x 800 dots horizontally, with each dot using 8 bits to take on 256 different colors. (actually, a dot is called a pixel).
Need 8 bits to represent 256 colors ( 28 = 256). Total number of bits needed to represent the screen is then:
600 x 800 x 8 = 3,840,000 bits (or just under 4 Mbits) Your video card must have at least this much memory on it.
1 Mbits = 1024 x 1024 = 210 x 210 = 220 . 1 Kbits = 1024 = 210.
