File size calculations👇

1) sound file size = sample rate x duration (s) x bit depth

2) image file size = colour depth x image height (px) x image width (px)

3) text file size = bits per character x number of characters

Thank you, thank you so much. My computer science mock is tomorrow and my computer science class this year has been a wreck. We've had 3 different teachers and only the current teacher has actually been any good. We had to have the mock pushed back until after work experience to give our current teacher enough time to teach us the basics. That's how bad the other teachers were. So this video is a lifesaver.
