A video game displays images on your monitor having a full HD resolution (1920x1080 pixels). Each pixel contains R, G, B LED's, and each LED is controlled to shine at one of 256 levels. The game produces a new image on the screen 25 times per second. How many megabytes (MB) per second are being sent to your monitor while you are playing your game?

Ответ:
1920x1080 = 2073600 pixels in FHD screen
1 led have 256 levels = 1 Byte
1 Pixel have 3 color = 3 * 1 Byte = 3 Byte
1 FHD picture is 2073600 pixels * 3 Byte = 6220800 Byte
If the picture change 25 times per second
6220800 Byte * 25 = 155520000 Byte in second
or
155520000 Byte : 1024 = 151875 Kb in second
or
151875 Kb : 1024 = 148,3 Mb
