Welcome to the (almost) Annual Computer Science Lockdown Quiz 2! This is a quiz about all things computer related! Good luck all, I hope you do well :)
Big thank you to Sam and Julzy for their awesome hospitality :)

Ah yes, Logan Paul, my favorite processor.
yea, I remember that the Logan Pauls were dominant in PCs as far back as the 1720s
I cannot believe it's been a year since the first one. That was great fun, thanks again Creel :)
Cray's compute dominance goes back to the sixties, not just the 80s/90s. CDC-6600 was the fastest computer in the world in 1964 (3 MFLOPS)
man and my PC can pump out Teraflops...
Got all the last questions wrong. Gotta watch movies.
Mom : why are you always watching movies?
Me : I'm practising for computer science quiz.
Nice one, but most of the questions were ludicrously easy for anyone who has a passing interest in computers. I did 23/24, I was pretty sure shub nam blarb or whatever was made up :) Also I don't go for all that kibibyte mibibyte nonsense. A kilobyte has always been and will always be 1024 bytes. If you had a single power of two in that question I'd pick it out of protest :)
This staff is absolutely amazing! Thanks 👉🏻👉🏻
Flub flub shub? Haha. The only hard question
Really cool quiz,just a different thing to do while having lunch
You need to do a series on operating system stuff. Love you creel.
Lol I was annoyed when the answer was 1000. Glad too see that you see the truth though. It is a made up word 😂
Kibibyte and the seperation of base 2 to base 10 is to make conversion make more sense. In reality it is 1024 bits but the prefix Kilo means 1000...
Without the kilobyte being 1000bits the prefixes get messed up
Missed exactly one in each round. Fun stuff
The Cray supercomputer is part of the Jurassic Park lore.
"Where is the High Memory Area (HMA)?"
HMA is a funny quirk of memory addressing from the days of x86 real-mode 😅
Ha! I can't remember, is it harddrive? Maybe that was expanded memory or something...? I do remember the overlapping addresses for the same RAM. Yup, DOS memory was a mess for a while back there :)
@@WhatsACreel It's the first 64K of RAM above the 1MB (20-bit) address limit, accessible due to real mode's segment:offset style addressing.
Vague memory but I believe it was between 640kB (or kibiB 😂) and below 1MB
@@AlessioSangalli not quite, that's UMA (upper memory area). Though much of it was used by devices (I still remember segment 0xB800 was where text mode video memory was).
Ok, that's good to know! Thank goodness we have flat memory nowadays, the DOS days were hectic!
Great stuff, Creel! Nice hidden references ;) Lovely to see Queeg pop up, I haven't seen that episode in years.
I'm afraid I only got 22 :(
I didn't listen one question properly and picked the slowest-algorithm-for-large-n, not the slowest-to-become-slower-as-n-increases :P
and the random numbers, I just didn't know. I figured you could maybe use something about primes to make pseudo-random numbers.
I appreciate the effort you put into these fun lockdown activities.
This is great!😀
20/24, music on point, thanks!
Excellent sir
good old queeg
That was fun. Thx:)
Very fun quiz: 19/24
Yesterday, i happened to see the 1st quiz in my feed again so i did it. and the day later a new one after a year. Nicely timed!
I got two wrong on the 3rd round. Not keeping pace with my supercomputers clearly. :)
20/24. I missed one in every round. Gotta catch on my supercomputer knowledge.
for (int i = 000; i < 010; i++) { ... }
How many times does the loop's body execute?
(Languages with a C lineage interpret integer literals with a leading zero as octal, so 8 times)
Indeed they do. Very tricky interview question.
Ha, got me with that one :)
This is my most hated feature of C. I have to confess that in many years I have NEVER used octal, I find it so useless, and to use a prefix like 0 that should be of no consequence instead changes the base of the number. Totally crazy. And still, C does not support binary literals that would make code quite readable in some cases.
And, it's a feature present in Java and Javascript. So it lives on...
@@phasm42 and PHP as well. 07 + 01 = 10. Blows people's minds. That said I've never seen a bug caused by this because people tend not to use the leading 0.
back in the good old days we used k=1000, K=1024, b=bit and B=byte so 64 KB were really 65536 bytes in our beloved C64s but 64 kb/s only 64000 bits per second speed over ISDN landlines...
21/23. Got them all right except for the pop culture/history ones.
not bad, only 3 wrong! I'll go look up EDVAC... Good music choices too, Creel!
yes, very fun!
i know what a BIOS is, i just wrote down the wrong letter. IDDQD put you into god mode in DOOM1.
Ha! Just use IDCLEV to go back and do the question again :)
got 21; Westworld, BlumBlumShub, and IBM Summit
Damn my knowledge of perlin noise being made for tron, it doomed me here.
And my lack of knowledge of algebraic algos evidently.
20/24, 83% not bad, I need to brush up on my computer science trivia xD
we need the 2022 edition
Great!!!
23/24 Missed the pseudo random number generator question.
Same here!
Wow! Nice one :)
Ditto! Lulled into a false sense of security by the other questions!
Same 🤣😒
Never heard of the General Number Field Sieve either.
Got only 2 wrong, 1 by not paying attention to the answers 😂
very fun :D
PIC 10F200 lol
cray believed in speed over accuracy so the cray 2 would come up with a wrong answer faster than any other computer :)
errr wasnt the correct answer boith 11111111 and 255? )
Yes, but the other option was 256 not 255 :) I had to double-check, I was like, wait those two things are the same!
@@aihtdikh guess my eyes are going all squirly lol i was sure it was 255 not 256 :)
How about some payback.... no cheating now!
What do MFM and RLL stand for?
also what does GCR stand for?
what did G=c800:5 do back in the day?
which x86 opcode couldbe used to differentiate between an Intel processor an an NEC V20 clone?
Hi Creel, you've tackled impressive technical topics over the years and I am just curious: what is exactly your background? Is the content of your channel actually related to your profession? Thanks!
It’s related, yep, I have a comp sci degree. Mostly code databases for stats. Cheers for watching :)
@@WhatsACreel Ah, so the amazing level of asm knowledge is just a hobby? Nice work, sir!
19/24
23/24. Now I shall go and study pseudorandom generators
That's a fine score mate, well done :)
@@WhatsACreel I watched this (and the previous quiz) with my son, he recently showed interest in this field. Thank you, absolutely fantastic. The question I liked the most was the Cray, the moment I saw the picture I knew the answer even before I could see the options 😂
22/24
...
ok I'm not great with movie references... or references in general
22/24
Got the first 2 image questions wrong.
So it does NOT lay eggs?? Bullshit quiz this! lol
what an useless processor
20/24
Good score mate, well done :)
kilobyte is a made up word as well.. and kilo has meant 1000 forever.
hi
G'day :)
So Kibibyte is a made-up word, but you're fine with Kilobyte, obviously since it was discovered and not invented? wat
You all are STILL in lockdown?
Middle of winter for Oz - I guess covid's going ballistic down under
Not really, no. Lockdowns come and go around here. They get little outburst of cases and the towns lockdown for a while to contain it. Mostly I just figured I'd contnue with the same name as the last quiz. Cheers for watching :)
@@WhatsACreel i would be in full panic mode if we were still in lockdown is all 😜 but then again, Australia has amazing weather all year around. If I ever get a chance of moving from the dark north I will. 😅
23
Btw, it's unfair to compare Logan Paul to 40 years old CPUs. He's only a humble youtuber.
Creel, it's Alan Turing, not Allan Turing :)
Oh, it is too! Well spied :)
got only the movie ones wrong u.u
"What is aquadag?"
Errr... (Google's it). Seems to be some kind of coating they use inside CRT's. Is that right?
@@WhatsACreel yeah, it's the conductive black coating on the inside (and outside) of CRTs. So you've got two conductive layers, separated by glass... a big capacitor. Related, if you've opened up a CRT and notice various bare metal cables strung around making contact with the tube, that's grounding to the outside layer of dag (the big red wire and suction cup looking thing is connected to a contact that energizes the inside layer of dag).
@@phasm42 Oh, that's good to know! I did open them up a long time ago. Pretty dangerous! Interesting stuff, cheers for sharing mate, have a good one :)
I got every single question correct and not a single question was difficult.
There are 24 more bytes in a kilobyte than the correct answer says there is
Not that I'd profess to be able to tell you a single thing about computer science Creel
