Hi, my name is Samir Malik. And I'm a private tutor for Middle school and High school students in the Austin area. Today, we're going to be discussing on how resolution is measured. Now resolution is measured in both horizontal and vertical pixels. To find resolution, we first calculate the number of dots on a line. And then we calculate the number of lines on the screen. To find the resolution. So for example, a resolution of 1600 times 1200. Would mean that there's 1600 dots on that line. Times 1200 line on that particular pixel. Another example would be 640 times 480. Resolution of 640 times 480 would mean that we have 640 dots on a line. Times 480 lines on a pixel. So this is how we define resolution. And of course, how resolution is measured. And we see how resolution is being measured. By using the vertical and horizontal ways to calculate the measurement.
