Network Types and Performance

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!

This channel doesn`t get the recognition it deserves.

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.

[kookieskosmos]

anyone else powering through these for monday?

[shaunakkaryekar]

you are a life saver as you have the only cs series for as and a level, great work man!

I am in year 9 and I took my computer science GCSE early and this definitely helped thanks

[alizashafi]

Exam is tomorrow morning and i am so grateful that i have come across this !

[agsharansakthitharan]

You are the god who is gonna save me from exams

[zebroar]

I just wanted to thank you for that B in Computer Science GCSE! Although it's late!

[anushiyagunarajah]

I thought i was late to start studying but then these dudes are studying day before exam

[devnyorm]

Thank you. Good video, helped me understand networks more...

[seangriffin]

thank you thus has been great for a crash course revision

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.

Does this particular topic covers the new Cambridge 9618 syllabus?

Why would the bandwidth be greater with wireless? Shouldn't it be better with ethernet?

[chenrui]

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?

[mernistasphes]

is bandwidth shared only across wireless networks? or is it shared for wired too?
