Great explanation. All in one short video as well.:)

[@RepofTurkeyClan]

Thank you for this clear explanation.

In the edexcel exam though, when they ask about file size for an image - the markscheme seems to want you to use 1024B = KB...not 1000 (which we only use for file transmission speed I think)

Great video tho I was kinda hoping that you give an example (i.e. Sakura pink is 255,183, 179 in RGB Decimal is to what in binary).

Can you go into detail with pseudo code and the logic of answering an exam question on it please. Your videos are amazing by the way. Thanks x

[@user-es1pk4og1z]
