For Computer Science I had a teacher that was a great person but not a great teacher and really didnt teach me the topics very well but i hope these videos can help as my exam is on Monday. edit: mans at uni now chilling, these videos deffo helped safe
I watched all your videos, made notes from them combined with the CGP guide and the exam wasn't as hard as i thought it would be... Thanks for awesome videos
My belief is the A/LU is written this way because this part of the chip performs two functions: arithmetic and logical computations. Arithmetic will perform math equations (not in the sense of using a calculator). The logical will perform if/then/else statements.
Thanks for doing these vids I just started yr 11 and my teacher expects me to get a 7 in this. I understand little things, here and there, but ur vids just make it so much easier to learn the content than to read through 300 pages 😂
gonna complete the whole spec in 2 weeks, my real exams are so soon and my teacher cannot teach for shit i will update with my results (aiming for a 6), MrBrownCS is a livesaver
With regards to the Von Neuman bottleneck, is there any way to increase the bus/wire efficiency or speed? Is there a limit to this? As everything else improves with technology memory, CPU (ALU, CU) is this (wire speed) going to be a limiting factor in this architecture? Thanks.
OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO THANK YOU MR. BROWN CS. bLESS YOU young soul! YOU ARE A TRUE HERO AND EDUCATOR.!!!!!!!!!!!!!!
Everybody who has an upcoming test. You, yes you: To begin with, I am wishing you all the best, believe in yourself, you can do this! Very good luck, and I hope that you (yes you) will smash Computer Science GCSE.
Hey on my exam sheet it says the board is WJEC/GCSE is this the right playlist for me? i have 0 revision and need to past badly. exam is on monday... any hope? lol
There's a WJEC specific one on my channel but it's incomplete atm unfortunately - it covers the key things but some specifics are missing, so please look at the specification to see what's missing and try and go over that. Definitely still hope!
muda fuckka im shitting myself nigga ive flopped this whole computer science year i got 7s in everything else but i got a 2 in computer science!!!!!!! FUUUUUUUCK i hate this subject and dont say dem tings bruv.
would making notes on all of these videos be helpful as well whilst watching them? Computer Science exam on Monday and it's currently 13:30 on the Saturday! Need to cram!
Many Thanks! also, have you got any videos on writing psuedocode? it's my Achilles heel!! (haven't looked through all your videos yet so apologies if I'm just being lazy)
hello! do you need to know about the registers involved in the fetch/decode/execute cycle? I sat an exam where you got marks for mentioning the mar, mdr and program counter and now I'm panicking. thank you!
Thanks man, I have an exam tomorrow this helps D: I completely forgot. I'm probably screwed… Anyway time for ritalin coffee and a whole lot of studying.
So the other answer isn't quite right - the cache and registers are two separate things. Registers are very small bits of memory (maybe 64 bits in size and maybe there'll only be ~30/40 in total) that are on the CPU. Cache may or may not be on the CPU but they're still small compared to RAM, but larger than registers (slower too). Both are used instead of having to go to RAM constantly (as they are both fast). Think of it as registers store data used in one clock cycle, whereas cache for maybe 100 clock cycles. Have a look at the playlist on my channel for your exam board to see if you need to know about the special-purpose registers and/or L1, L2 cache - otherwise, don't worry about them more than what I've said
Yes, it's 9-1, and from now on all GCSE students will be graded with 9-1 rather than A*-E (in CS at least). All exams are in May/June not also in January, like the situation a few years ago
Can you do videos on the Edexcel NEA? I am starting it next week but am still unsure of some of the things u have to do for it such as test plans so I would be grateful if u could do videos on that.
+AgentB 13 sorry, I probably know way less about the NEA than you! I’ll try to familiarise myself with it after I finish the exam content but that won’t be for a while. Test plans aren’t too bad, see if you can find some templates online. Hope it goes well!
The NEA is dependent on what language you learnt in school. I learnt Python (along with most schools), though C family languages and other OOPs and High level languages are taught. Therefore, it is pretty difficult to teach the NEA
Anyone else have a shit computing teacher and is watching this to try to learn the whole course by tomorrows exam 😂😂

shush
Do we need to know about the involvement of the program counter, MAR and MDR in the fetch - execute cycle?
Depends what exam board you're doing - if you do (like for OCR) then the next video in the playlist should explain their roles

Did it work?
Sorry, but is the additional bus that connects the CPU to the input and output devices, part of the Von Neumann Architecture
Yeah, and the architecture is referring to the whole system, not just the CPU (and remember it’s just a model)
would making notes on all of these videos be helpful as well whilst watching them? Computer Science exam on Monday and it's currently 13:30 on the Saturday! Need to cram!
Yes absolutely - don’t worry about making the notes too pretty but still write them in your own words. Good luck!
haha same here, I should of started to revise earlier but am now starting
Many Thanks! also, have you got any videos on writing psuedocode? it's my Achilles heel!! (haven't looked through all your videos yet so apologies if I'm just being lazy)
That's common with lots of people, though it's not actually that bad - one of my latest vids (on answering algorithm Qs) talks about it quite a bit
Here a night before an exam as usual
hello! do you need to know about the registers involved in the fetch/decode/execute cycle? I sat an exam where you got marks for mentioning the mar, mdr and program counter and now I'm panicking. thank you!
Yes
I think for ocr you need to know about the mdr mar and pc
Will there be any videos on Algorithms and pseudocode?
+Subwaytion25 yes, absolutely!
Thanks for the video. Really helped me out :)
Will u make 2021 paper walkthroughs as well?
Greetings from the 2EHIF
WJEC (in Wales) has brought out a new specification. Does this series apply to it?
Yeah, the videos in the playlist do, but it’s not complete unfortunately, so make sure you revise any missing topics

Thank you so much my teacher for this section of the course is awful ! You summarise it perfectly :)

Does the CPU or the control unit activate the necessary circuitry in the execute stage?

do we need to know about the stuff at the bottom of the playlist for paper 1

no cpu perfromance is paper 1
Could you do a video explaining how to tackle unit 3 (programming problem practical assessment), please?!

2:36 so whats in the registers? Is it l1 cache l2 cache or mar and mdr. Pls reply cus i have no clue

Computer Science Tutor thanks a lot for clearing this up - your videos are fenomenal
the main memory is the RAM, and its not the same as registers, registers are small storage inside the cpu
When will paper 1 and the rest of the videos be released
I can't say for certain, as soon as I can
so helpful i love
wish you were my computer science teacher
