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). Actually no need since I already searched for it as 111111111011011110110011 . But what I´m curious now is how the .dat file? or file containing these binary data would possibly look like. Would it be similar to an Excel file with rows and columns for each pixel in binary. Anyways, thanks for the video. Funny how studying science makes me interested in the details behind man-made things

Thank you for your explanation and effort and I am asking for a good presentations as yours. I am from a developing country. It is the first time to teach this curriculum in my country, so please I need your help to get presentations as yours if it is possible. Thanks very much.

What sort of stuff are we going to learn in A-level computer science OCR ? (It's okay if you don't know by the way, just wondering :3 )
@ComputerScienceTutor6 жыл бұрын
Basically the same topics, just in more detail (it’s more interesting!) 😁
@Wenedi6 жыл бұрын
Cool! :D Also does CS touch on 3D modelling at all? I am really interested in it but the school doesn't care at all D:
@ComputerScienceTutor6 жыл бұрын
Oh nice, the closest topics in CS are probably computer vision and parallel programming which are probably only covered at uni unfortunately - though don't let that put you off looking into it yourself! If you're interested in the programming side of it, and have an NVIDIA GPU, you could have a look at CUDA, which would be used for intensive applications like modelling

I'm using blender atm, went through a bunch of courses on udemy and after the exams will buy subscription for the cgcookie.com/course/modeling-realistic-characters-with-blender course , and maybe when I will feel kinda mad I will get this bad boy :3dclassroom.cgmasteracademy.com/elective/2136 I think that it will end up with me only dreaming about making something even close to similar... but I will have hope :) Hopefully the study at uni will help me with my career :D

Some exam boards overlap topics (AQA mostly) -- I'd recommend checking the specification if you have any doubts about this kind of thing
