Sir this is really useful and helpful and all and I appreciate the explanation, but I have a small question. How come in this part of the video (8:21), why is 12/2=6 how is there a remainder of 1, but when you did 6/2=3 and there is no remainder? Same with 3/2=1 but there isn't a remainder I am confused.
if we divide with 2 and it is a perfect division for example 2 divided by 12 equals 6 which does not have any remainder therefore it will not have 1 remainder the remainder you are talking about is from the upper box where we divided 2 by 25 which is an imperfect division thus having a remainder
at 9:08 when converting 67 into binary numbers, isn't the answers supposed to be 1000011 instead, I am confused p.s nvm I know why did u put an extra zero in the front now
ok... it is an 8 bit register, therefore the numbers refer to 128, 64, 32, 16, 8, 4, 2, 1... there are no 128s, 1x64 and 1x2 and 1x1 . So yes, you are correct with 1000011, but the extra zero at the front does signify an 8 bit register.
so the byte is a bunch of information stored as numbers and it is actually numbers too so for example we have the number 28365016 so how will the computer know what this information of numbers is?
The number 28,365,016 can be represented in various number systems: • Decimal (Base 10): The form humans typically use, which is 28,365,016. • Binary (Base 2): The form computers use, which for 28,365,016 is 1101011111111010110111000.
The teacher no one asked for, but the teacher we need.

so do we need to learn this formula p.s ive already learned it in a second but still
Hello! I've just started CS. Could I know what lots are? Like when you said 2 lots of 10,000? What do they mean?
It basically means 2 x 10000
man ur a lifesaver dude keep making these vedios really appreciate it ❤️❤️
Glad you like them!
Massively appreciated! Thank you!🥹

@@mrbulmerslearningzone I see, thank you so much! The videos are really helpful I have got a 9 in my test last time
Thx, i have my exam tomorrow
I just want to thank you you saved me now I understand CS❤❤
thank you for your kind words
Thanks a lot. very useful
It's really helpful
sir mr bulmer i want to know which book u use or which book u recommend for computer igcse
Nice
thank you, u saved my life
😀
can we use this for o level examination !!
absolutely
tysm :D
👍
i’m still unclear at the 27639 part. could u please explain further?
Is this also applicable for GCSE - O Levels ?
Most of the syllabuses follow a similar pattern…especially with Data Representation…
so the byte is a bunch of information stored as numbers and it is actually numbers too so for example we have the number 28365016 so how will the computer know what this information of numbers is?
The number 28,365,016 can be represented in various number systems:
• Decimal (Base 10): The form humans typically use, which is 28,365,016.
• Binary (Base 2): The form computers use, which for 28,365,016 is 1101011111111010110111000.
@@mrbulmerslearningzone thanks sir!
and if the number is in thousands we cannot do these methods
sir how can i get your notes?

can anyone send me a front copy of the book that is being used in the video plz?
THE GOAAATTT🐐🐐🐐🐐
When I read textbook. I couldnot understand all the things but now I am well.
We’ll get through this….you will do well :-)
