Calculate the amount of data transmitted per second from the video memory to the monitor in the mode of 1024

Calculate the amount of data transmitted per second from the video memory to the monitor in the mode of 1024 * 768 pixels with a color depth of 16 bits and a refresh rate of 75 Hz.

An image with a resolution of 1024×768 contains 786432 pixels.

Let’s find the size of one image – for this we multiply the number of points by the amount of memory occupied by one point:

786432 * 16 = 1258912 bits

There are 75 such images per second:

1258912 * 75 = 943718400 bits = 117964800 bytes = 115200 kilobytes = 112.5 megabytes.
