- Introducing the terms PAN, LAN and WAN as well as two usage models. I also briefly talk about factors that affect the performance of networks.
Made primarily for OCR GCSE Computer Science (J277) Paper 1. If you are following another course, be sure to use the playlists on my channel.

Thanks mate. Your voice really helps me keep the info as opposed to the monotonous older people who bore me half to death. Thanks!
😂
🤣🤣
fr i sleep on those videos
This channel doesn`t get the recognition it deserves.
I've never even heard of a PAN before and I have my exam later. Thanks babes.
Why don't you just smack his ass?
babes?
you're doing god's work here my dude
My computer science teacher is apparently one of the best, her along with your videos will hopefully really boost my grade. Thanks, you have a new sub.
boost
anyone else powering through these for monday?
Me. Try it on 2x speed if it's taking too long
yep
My guy
Yep :)
kookieskosmos me
you are a life saver as you have the only cs series for as and a level, great work man!
there is craigndave. They are masters at their craft
Exam is tomorrow morning and i am so grateful that i have come across this !
You are the god who is gonna save me from exams
Good luck guys for tomorrow
i love how u naturally assume my test is tmmr
Haha yep
@@che640 this was like a year ago😂
@@khadz4life540 the test was horrible tho
@@khadz4life540 i thank u for replying and for that u earned urself an extra sub :)
I am in year 9 and I took my computer science GCSE early and this definitely helped thanks
What'd you get?
Feel old yet?
@@spphinx welp im defo older now lmao. studying software engineering at university
Good to hear ur still on the route
I just wanted to thank you for that B in Computer Science GCSE! Although it's late!
+Pl0x Ayuda not at all, I’m really pleased to hear that 😀
I thought i was late to start studying but then these dudes are studying day before exam
what about it lmao
Mitchel Geddes, for sure there are going to be very low grade boundaries. There aren't many qualified computer science teachers (I didn't have one, so that's why I find this Chanel so useful), and we don't have the NEA anymore. On top of that this subject isn't easy, therefore the grades boundaries will be low, in my opinion. And to be honest, I hope they are low cause otherwise I'm not passing.
ye our teacher got injured in october and had substitutes ever since and our skl spent so much time on coursework
im gambling on grade boundaries too
Nu ma asteptam sa gasesc pe cineva roman si aici=))))
Buna Cosmin=)))
Bafta azi :)
thats deep then, because from what i seen most people found the first paper easy, so the boundaries are likely to be high
Thank you. Good video, helped me understand networks more...
thank you thus has been great for a crash course revision
Anyone else got their exam tomorrow?
no
Yes, how are you feeling?
Joe Holmes I feel ok for most exam, but I'm nervous about computing.
Haha, I suggest just trying to cram everything in. Going through these videos/ books. Maybe writing notes on the spec?
me im shook
Does this particular topic covers the new Cambridge 9618 syllabus?
3 hours left till exam, learning it now. I should be fine.....
Why would the bandwidth be greater with wireless? Shouldn't it be better with ethernet?
same qs
I am interest, thank for million
very helpful content...thank you...
Thank you !
Exam tomorrow anyone?
GC SE how much work you done?
More like exam in an hour
A question, sir: your playlist is titled 'OCR A level Computer Science' but the content more closely matches that of GCSE. Is there a separate GCSE playlist or are both included in this one?
Joe
I’m in year 9 but I just want my predicted grade to go up.
is bandwidth shared only across wireless networks? or is it shared for wired too?
Hi, I know I comment a lot but my exam is 4 days away and I need some advice. My teacher makes the topic about Ethical and Environmental issues out to be like some huge topic that we need to spend loads of time revising for. However, I really struggle with networks. I haven't really revised either of these topics much yet (I've revised most other things) but I want to know do you thing I should spend loads of time on networks or focus more on the Ethical and Environmental issues? Personally, I'm leaning towards focusing on networks as the specimen paper seemed to have loads on it and little to nothing on the Ethical and Environmental side of things.
You have time to revise everything (4 days will seem like a luxury this time next week!), but personally I'd focus on networks, as you can't wing that as much. You have to understand the concepts, whereas the ethics/legal/environmental Qs are mostly application based, where you have to give opinions. They do tend to be longer mark questions though, and there are still some terms you need to know, but that won't take too long to cover
Computer Science Tutor ok thank u
yep
how come this context does not matchup with the ocr cambridge revision books
What doesn't match? Please don't trust the textbooks too much!
Computer Science Tutor
Hi, i would just like to say I really appreciate your work, my exam is tommorw and I was so stressed out by it. Fortunately I found your videos and they have simplified everything and now I have confidence for the exam... Thank you so so much ! YOU DESERVE MORE RECOGNITION !!!
That's so great to hear, thanks! Good luck :)
Computer Science Tutor
Thank you :)
none none This is the Edexcel spec
I got a 9
Thank you man
good luck for tomorrow ya'll :((
how did it go?
please upload for paper 3 and 4 ......
last minute revision gang where you at
Just thought I should point out some mistakes with this video...
For performance the specification has this:
Explain the effect of the following on the
performance of the CPU:
• clock speed
• number of processor cores
• cache size
• cache type
why are you talking about latency, bandwidth and error rate?
Furthermore the specification requires knowledge of star and bus topologies, not Peer to peer.
I'm not quite sure what you mean about not mentioning hardware performance here, it's a bit of a non sequitur because that's a different topic and it's covered by another video. Same applies for the topologies, I have videos that cover those both. For peer-to-peer, I'm not sure what spec you're following but I try to make these videos as general as possible so it's possible your course is one of the few that doesn't cover the two network models
@@ComputerScienceTutor I was pointing out the fact that at 4:47 you mention 3 aspects of performance, none of which are in the AQA gcse specification, despite the fact that they are in a playlist for AQA GCSE videos.
I wasn't saying that you hadn't fully covered the topics of topolgies, rather that you had mentioned aspects of them not in the AQA specification
@@eliabenson4201 you're talking about factors that affect the performance of the cpu, not performance of a network, and this is the ocr spec
@@eliabenson4201 these videos aren't 100% specific since there's so much overlap between exam boards. this vid is also on the ocr playlist and yes there are a few pieces that aren't on our spec (eg PANs) but its still a bit of extra useful knowledge and doesnt make much of a difference
watch this video at 0.75x playback speed
thank me later
is this loss?
I am sorry but you are telling me one thing; the textbook is telling me another; the CGP revision guide is telling another. I feel like crying...
What's not matching up? Textbooks + CGP seem to include whatever they want so you have to be a bit careful
Computer Science Tutor bus topology and star. Is that different from client to server and peer to peer
Can you make a video for NEA help?
+Lelouch Vi Britannia I’m not sure, what videos would be helpful?
Lelouch Vi Britannia well u defo won't be needing that now whether u r in year 10 or 11!😂😂😂
Cosmin, chair nu a fost rău. Sper ca te-ai descurcat.
0.42 the only weak point in a system is
yourself and the system
i have my exam tomorrow and I'm not looking forward to it
how was the exam
Very helpful but would appreciate it if you could talk a bit slower
lol i put it up to 1.25x cuz its too slow
use settings and slow the video down
nah his speed is calm
Who else has their exam tomorrow?
Mans ina exam rn g talk faster
Talk quietly too g
