Compute the memory requirement of the frame buffer for the system having resolution 1280 x 1280 and supports 24 bits per pixel.
Number of pixel = 1280 x 1280 = 16, 38, 400 Number of bits = Number of pixels x Number of bits/pixel = 16, 38, 400 x 24 = 3, 93, 21, 600 bits = 39321600 / 8 = 49,15,200 Bytes (∵ 1 Byte = 8 bits) = 49,15,200 / 1024 = 4800 KB (∵ 1 KB = 1024 Bytes) = 4800 / 1024 = 4.69 MB (∵ 1 MB = 1024 KB) Thus, the system having screen resolution 1280 x 1280 and supporting 24 bits per pixel require 4.69 MB of memory for the frame / refresh .
