What information is in the video memory? How many bits of video memory per pixel is required

1.What information is in the video memory? 2.How many bits of video memory per pixel is required to store two-color; four-color; eight color; sixteen color images? 3. What colors are obtained by mixing red and blue, red and green, green and blue? 4. How many colors will the palette contain if each base color is encoded in two bits? 5. Think of a way to encode colors for a 256-color palette. 6. Let the video memory of the computer have a volume of 512 Kbytes, the size of the graphic grid – 640 x 480, How many screen pages will simultaneously fit into the video memory with a palette of 16 colors; 256 colors?

1. The video memory stores the initial (unprocessed), intermediate (in the process of processing) and final (ready for display) data.

2. To store a two-color pixel, 1 bit is required, a four-color one – 2 bits, an eight-color one – 3 bits, a sixteen-color one – 4 bits.

3. If you mix red and blue, you get purple. Red and green are yellow. Blue and green are blue.

4. Four colors.

5. If you use a binary system, then 256 colors is 8 bits per pixel. The color coding can then be from 00000000 to 11111111.

6. One.
