Hi I started studying while listening to your lectures and it helps me so much. I just need some guidance at chapter 8 I hope you will have lectures of it soon! Looking forward to it.
There is very good examination for my university (UNSIA) Siber Asia University and my own leason in the class the name is "Data Communcation". Thankyou Mr Blumer's
If the processor voltage cannot be guaranteed then the data line voltage also cannot be guaranteed. With this system of voltages even if the 5v line sags the data line voltage can still be guaranteed. This guaranteed voltage is necessary to keep clean transmission for full speed and high speed USB. The USB is designed to run at 3.3V…the 5V is to allow for a dip.
There is plenty of explaining… my videos correspond with the textbook, but the text isn’t repeated. If you have specific questions please ask. I am here to help. Thank you for your feedback!
Asslm o Alaikum! Sir can you plz make the video on Chapter 3 Hardware solution activity 3.3 and 3.4. if it possible because this is only platform where we get solution of our problems.
@@ashwikaagarwal5637 thank you for the question... remember here we are only talking about Serial or Parallel Transmission types, so speed and distance are the key factors. In the first question the printer is close to the computer, but is speed of data transmission important? In the past Parallel would have been the obvious choice but now a USB Cable would be the correct solution...this would be the same for the weather station question. Again the third question is a little confusing; ideally parallel would be the best option, but again a USB Serial Cable wins with it being universally compatible. The final question relating to internal components can only be parallel due to distance and speed required... I do hope this helps
My actual computer science teacher is literally useless, you are an absolute life saver. Words cannot explain how grateful I am for your existence.
haha....mine too, my computer science teacher always leaves most of the important topics.
same goes for me
Same😭
Same
Same bruh
you are the computer science teacher we all needed
you are too kind :-)
you're saving my mid terms right now
@@splat_oon glad the videos are helping :-)
thank you so much you're videos are truly helpful for 2023 igcse cs students
My schools Computer science is so trash you are actually a life saver Thanku so much to help us out! :))))

Thank you for your kind words :-)
Sir, could you upload a video on the specimen paper 2023 it would help a lot
Ur the man, im really struggling as i just switched my field from medical to computer sciences, i hope it gets better
Salaam. Can we get the answers of the activity and exam style questions. It will be great help
Thank u these videos are a gift
I'm litterly watching ur vids 1 day before my mid 😂😂
Ur a hugeeee live saver thank you so much very very helpful
SAME!!!!🤣🤣🤣🤣
U are the best man Mr Bulmer best teacher ive seen by far
Great videos

thank you mr bulmer for this video it really helps
I’m glad it has been useful
Thank You !
Welcome!
very nice video, keep up the good work
very helpful 😊
My teacher lecture is bla bla you are saving my life may God bless you
Sir! can you tell the reason about p2 that cambridge first upload paper on it now but they stopped it but why
Pls explain what is meant change in voltage on the data signal wires in USB cable

I was in need of serious help, as I was a boi student before (Done my full bio course btw). Thank you so much for the help Bulmer sir!
Glad I could help!
can i get these slides
Can you do more of explaining rather than just reading the text out, please.. the text is available in the textbook as well.

You are a lifesaver thank you so much for last minute prep 😂😂is it possible to get notes?
also where can i get the softcopy of this book?
I know that PDF versions exist online...
Asslm o Alaikum! Sir can you plz make the video on Chapter 3 Hardware solution activity 3.3 and 3.4. if it possible because this is only platform where we get solution of our problems.
Ok…give me a little time… I’m on it!
@@mrbulmerslearningzone Thanks sir! May ALLAH bless you✨
He should have more than 100k
@@lapsaispro yes
Is there a topic that explains what a network is..i think one has to know about the network before data transmission!
Not really no...there is little mention of topology.
You should monitize your channel. Would be nice for you and would be our way to pay back the wonderful lectures you give us
Thank you for your kind words 🙂
Can I get soft copy of the second edition
