Hey everyone, thanks for watching, hope the video helps! :) By the way, you can purchase the slides I use here for personal revision (students) or teaching (teachers) 😉 www.jamesgan.net/igcsecs Thank you!
1:13:28 for correction, the laser light does not reach/hit the sensor once it's reflected back from the bump... this is thus registered as 0 whereas the flat region makes perfect angle for light to be reflected back to sensor therefore CPU interpts it as 1 [W VIDEO THO THANK YOU]
you're so underrated omg ur saving me for mocks rn, and the way that you keep repeating the relevance to the von Nauman architecture keeps everything making sense so I don't feel like I'm studying random concepts at once. LOVE UR VIDEOS
Thank you so much for explaining!!!!! This video helps me a lot! It really helped me to understand the concept. Thank you ☺️ god bless you and your family
The sensors chapter is useless. They dont ask us how it works. They are gonna ask us what it measures. In those large 6 markers they give us marks if we talk about the fact that the temperature sensor measures temperature. This is passed thru ADC. Digital data is compared with preset value. They know we know this yet they will keep such obvious questions in paper.
Hi, firstly I wanted to thank you for these wonderful videos; your content is truly amazing, hats off to your wonderful explanation. Also, I wanted to ask that is it possible that can you share the link for SSD which you mentioned in the video if possible?
Amazing explanation sir! I’m truly grateful… I’d like to mention that the output devices “part” wasn’t included in this video, would it be possible For you to upload it independently, or add it in this playlist…
Great video really well made, one quick question so at first you say that the address from the PC is copied into MAR. Then you say that the address is searched for the next instruction from and that address is stored in MAR, then what happens to the address that was taken from PC.
Hi there could you confirm if the following has been removed from syllabus : How input and output devices work CD r and rw dvd r and rw etc as I find these in TxtBook but not in syllabus
Hey sir, I wanted to know if we require the learning of examples of embedded systems, like mentioned in the text book as the syllabus only states it as examples in the syllabus notes and says that we should be able to identify where they are commonly used. Do you think we need to know it as in deep as it is given in the book?
It’s good to know and understand the general concept. For instance the structure of an embedded system. Then, memorise 1-2 examples of ES. That should be good enough :)
U just need to know what they do and like what are the advantages and disadvantages that come with these devices, for example a question could be asked comparing the three types of touch screens, so in that question u would be required to list why the specific touchscreen eg: why is capacitive better than resistive touch screen type for example
Yes! It would be hard to “memorise” them. I would recommend you write down how each component work briefly (3 sentences) so that you can answer short structured questions!
This is what the official Cambridge FAQ says - Input and output devices - for the new syllabus first examined in 2023, are candidates still expected to know how each device physically functions as it is with the current syllabus last examined in 2022? For the current syllabus last examined in 2022, candidates need to know how each device operates. However, for the new syllabus first examined in 2023, candidates only need to understand what each device does, why it does it, and when it might need to be used, but not how it physically functions. So, no you don't
omgggg me toooo. you must remember something; even if u can’t bring out anything rn, as long as ur able to answer the questions on the paper. here’s a random fact: SSDS are faster and more reliable, thin and lightweight too. so basically, sonic but with the element of loyalty and he’s also a skinny legend

[W VIDEO THO THANK YOU]
Thank you so much. I’ll be having for my O level paper one this Friday ur videos help a lot I was worried about the exam. No stress free, thank you.
good luck!!

I hate this chapter but thanks to you it is much simpler to learn now! You deserve so many subs!
Same it’s the worst one idk how people say it’s easy
frr its the worst chapter and really hard to remember
Thanks alot for helping me for computer scienec p1 in the last night of exam
Thank you so much!! I have mocks in less then a week and your videos really help with revision
Excellent work sir hope u keep it up one of ye best lectures in n internet. Better than my 20k+ spendings on tutor and resources
YOU ARE SO UNDERRATED!!
😳
fr bro
Thank you very much for this igcse computer science series of videos. Very helpful!
Thank you so much for explaining!!!!! This video helps me a lot! It really helped me to understand the concept. Thank you ☺️ god bless you and your family
1:04:01
SRAM consumes less power than DRAM as DRAM requires periodic refreshing to maintain data stored in its capacitors...
thank you so much, Mr.James. You made it sooOOooOO easy to understand
Please keep up your work they really helped me and I am hoping for you to do more videos about ICT too before oct/nov igcse
thank you Mr James huge love from Pakistan keep going
Man u made my day, thanks a lot bud
Thank you for this video. It is really helpful for my exam. Thanks again.
you're a legend james
thank you mr james!

where is the output devices part ?

Thanks, I am using this in 2024 . Love from Pakistan 🇵🇰
JAY SHREE RAM
I hate this chapter but thanks to you it is much simpler to learn now! You deserve so many subs!
thank you this video saved my test
Thanks a lot for this video.
7:26, why does the address bus go to the memory DATA register and not the memory ADDRESS register?
Thank you so much, this video was so informative
And u help save my exam 🥰
Amazing explanation sir!
I’m truly grateful…
I’d like to mention that the output devices “part” wasn’t included in this video, would it be possible
For you to upload it independently, or add it in this playlist…
I agree with this
best teacher istg may God bless you best teacher fr❤
Sir can u make video on output devices?
Great video really well made, one quick question so at first you say that the address from the PC is copied into MAR. Then you say that the address is searched for the next instruction from and that address is stored in MAR, then what happens to the address that was taken from PC.
nice tutorials, am looking for output devices tutorial
thanks bro
thanks really helped out
alot!!
What country are you from?
Bro it helped so much
What about output devices???
Btw you are a great teacher and extremely underrated. I have my monthlies and your videos reaaly help to clear my concept
Fr🎉😊
Hi there could you confirm if the following has been removed from syllabus :
How input and output devices work
CD r and rw dvd r and rw etc as I find these in TxtBook but not in syllabus
It has not been removed
thank you so much
sir output devices are missing in the video
Hardware is making my head hurt
1:11:31
sir where are the printers?
Hey sir, I wanted to know if we require the learning of examples of embedded systems, like mentioned in the text book as the syllabus only states it as examples in the syllabus notes and says that we should be able to identify where they are commonly used.

@@jamesganleongyi thank you sir
2025 anyone?
can you also do A level plzzzzz
Hi what about the link sir
Do the students need to know the details of how these devices work?
i read from multiple articles that they have changed the syllabus so that u don't have to know how they work but just what they do BUT not 100% sure
U just need to know what they do and like what are the advantages and disadvantages that come with these devices, for example a question could be asked comparing the three types of touch screens, so in that question u would be required to list why the specific touchscreen eg: why is capacitive better than resistive touch screen
type for example
sir what about output devices?
Will you do more live coding streams?
Why output devices is not there
do we need to know how input and output devices work in 2023 syllabus?
Yes! It would be hard to “memorise” them. I would recommend you write down how each component work briefly (3 sentences) so that you can answer short structured questions!
nope
This is what the official Cambridge FAQ says -

So, no you don't
@@aravgupta4666 thanks
Sir where is the output devices 😢
1 day before my exam
sir, output devices??
i thought we didn't need to know the advantages and disadvantages of the devices?
we do!!
@@ITSMEEAGAIN-kd4nnare u sure 😭😭??
@@ArxlxnRbx thats what i was told by my teachers and friends
Bro that’s like the only thing we need to do hehe mainly cuz they removed the operation part of it. So only adv and disadvantage
@@Nai123-db7mi hehe thanks for confirming.., i got confused
sir can I get these notes slide
Do I have to remember every single instruction of the van Neumann architecture
yup
OUTPUT devices?
GOAT
How can I find past papers for this course?
search them
anyone else noticed the voice change in the 40th minute. 😂
no output devices??????
You forgot about output devices
Bro playing valorant while explaining
😂
Exam tomorrow and i dont remember anything i studied. Am i cooked chat ?
omgggg me toooo.
you must remember something; even if u can’t bring out anything rn, as long as ur able to answer the questions on the paper.
here’s a random fact: SSDS are faster and more reliable, thin and lightweight too. so basically, sonic but with the element of loyalty and he’s also a skinny legend
bro how did this end up coming in the actual gcse 💀
*god*
@@subsi9453 u are him
Am asking the same questions rn
@@subsi9453wow lmao
11:11 to 11:14 sound like a firework LOL
I have my boards in 2 days 😢
The way exam is tomorrow…..and I got so much left…..😢
Theory is not hard to master! Keep studying and last minute boost is definitely possible!
Awe thank u for the motivation. Still going strong!!
yoo i too play valorant
btw thanks
Output devices?
?????
istg i hate this chapter
