Explain the statement- CRT screen as a two-dimensional matrix
One can imagine the CRT screen as a two-dimensional matrix which has m rows and n columns and this is usually referred as raster. Each row of the m rows (or the points on a horizontal line of the screen) is called scan-line. The number of points that can be displayed on the screen (n × m) is defined as the resolution of the screen.
