Introduction to Binary

[@Z_W4]

Thank you so much. I struggled to understand this when my teacher taught it but you just saved my finals.

Can you please make a playlist on AS level Cambridge paper 2?

I want to hug you after finding this

this man is literally carrying my grade

[@samiradalla2402]

is this te basic understanding or does this playlist cover everything we need to know about paper 1 (it seems much more easier than it actually is or maybe im wrong?)

[@srn306x]

not really this doesn't seem complete

[@MrBrownCS]

For the current AQA, Edexcel, and OCR GCSE courses it's complete

[@ravenqi9305]

Plz also upload the Paper3 and Paper4 as well. Found this extremely helpful. Big thanks to the creator.

you are crazy! are you dreaming you have paper3 and paper4 in computer science?

@MrBrownCS is this playlist complete for CIE AS Level 9618?.

[@muna7025]

Hi, I have not done computer science as a GCSE but I've picked it as an A-level. I was wondering if it's possible for me to do well in this A-level course without fully studying the GCSE syllabus?

[@MrBrownCS]

Yes, absolutely! The A level courses are meant to be taught from scratch, so in theory you shouldn't be disadvantaged. I say in theory because if your class has mostly done the GCSE the teacher may speed up some of the GCSE-only topics. This just means some extra work may be needed on your part to catch up, but don't let that put you off. Often those in your position outperform those who have taken it before, because they haven't got that complacency. I hope you like the course!

[@muna7025]

Computer Science Tutor Thank you

[@Nithu342]

Just to clarify would you be going over said GCSE only topics because im in a similar situation. @Computer Science Tutor

[@MrBrownCS]

Yeah, the A level playlists on my channel have those topics in case you want a bit of a head start

[@a1hindisouthmovies]

of course u can muna

[@zoe6181]

if i am doing CAIE can i just follow the paper 2 OCR one that you have?

[@agjupiter]

can u post for paper 2 also

[@williamafflick9909]

does this playlist of videos cover every essential detail and topic that could come up on paper 1?

[@MrBrownCS]

Yes, it should do!

[@GamerBrozz1]

No, this playlist is for paper 2 !

[@nusaybahalamin711]

paper 1

[@MrBrownCS]

This video is in lots of playlists btw, as different exam boards require it for different exams :)

[@豪华徐-g2e]

I draw a logic gate by using a pen in my computer science paper1 exam, will that reduce my marks? Please help thanks!!

[@MrBrownCS]

No, that's fine! A pencil is only recommended so you can make changes easily.

[@ChrisLoucaides]

Do you have any predictions as to what will potentially be in the AS Paper 1 (CIE) of October/November 2018?

[@danyalstech4349]

Let me know if you find it out.

[@ChrisLoucaides]

I've done some statistical analysis, looking at questions that were in past June Papers and comparing them with October papers of the same year. From what I've seen there's usually around 4 Questions from the June papers that are similar to to some questions from the October papers. Here are my predictions: DBMS/SQL/Normalisation, Assembly Trace Table, Video/Image/Sound Compression, Parity Check, CPU Fundamentals, Some description of an internal operation, OS Management Tasks, Ethics, PHP. Also, what paper will you be doing, I'll be doing component (12) so if you'll be sitting another component and it happens to take place in a different time zone, let me know I'll tell you what was in (12) usually the questions are similar.

Hello, quick question do the two IGCSE computer science playlists cover everything we would need to know for all of the Cambridge IGCSE examinations which we will do in June 2018? Thanks

[@MrBrownCS]

Not everything I’m afraid, due to the nature of the IGCSE there’s a lot more than the normal GCSEs, so it will take me longer than the next few months to do, sorry

[@hoohoo8466]

[@ishtiyaqjaunnoo9135]

hi first of all i must say that this video was really helpful! But i have one question, 3:26 , 1 kilobyte isn't 1024 bytes instead of 1000 bytes?

[@Hamza-ef3uk]

For GCSE they keep it as a nice whole number. Apparently, it's easier to work with in the exam. I think at A levels you'll have to use 1024.

[@ishtiyaqjaunnoo3286]

yeah because sometimes there are divisble by 1024 in this case we can work out with 1024 otherwise 1000 i think

[@ejaz787]

@@Hamza-ef3uk A kilobyte is 1000 bytes but a kibibyte is 1024 bytes. People often mix them around but use 1 kilobyte is 1000 bytes in the exam.

[@ethan986]

Being in binary the computer works in 2s and more specifically the power of 2s. The creators wanted a number close to 1000 and the closest being 2^10=1024 with 2^9=512 and 2^11=2048.

[@ethan986]

But for GCSE you only need to know that 1000 bytes go into 1 kilobyte

[@hmzach9403]

is this for AS or A2?

[@MrBrownCS]
