Consider screen resolition 1024 x 512 pixel resolution. if refresh rate is 60 frames per secone .how much would it be taken to display 1 row of pixels.? and how do we define frames?

Given,

Screen resolution= 1024 x 512 pixels  |   (m x n)

1024 pixels is the size of the horizontal direction i.e length

512  pixels is the size of the vertical direction i.e breadth

Total pixels in the screen are = (1024*512) = 524288  

The size of frames equal to the 524288 pixels.

Refresh rate of the screen =60 frames/second

So, the total number of Pixels per second = 524288*60 = 31457280 pixels/second.

We want to display 1 row of pixels,or we can say 1024 pixels as 1024 pixels is the size of the horizontal direction i.e length.  

Seconds = (1024 pixels)/(31457280 pixels/second)

               =0.00003255208 seconds

A frame is one of the pictures, and the frame rate is a frequency metric,how often a fresh frame updates the video. This translates into the frequency at which the game redraws the picture on the screen for video games. Frame rate per second (fps) is measured in frames.
