Is there enough video memory of 256 KB to operate the monitor in 640 * 480 mode and a palette of 16 colors?
| September 16, 2021 | education
A 640×480 image contains 307200 pixels.
One 16-color dot takes up 4 bits of memory.
To find the total amount of memory that an image occupies, you need to multiply the number of points by the amount of memory that one point occupies:
307200 * 4 = 1228800 bits = 153600 bytes = 150 kilobytes.
Yes, that’s enough.
