How do Computers even work? Let's learn (pretty much) all of Computer Science in about 15 minutes with memes and bouncy music. At least the stuff worth remembering if you want to get into programming.
Of course this is not ALL of Computer Science, but I tried to condense a broad spectrum of topics as fast as possible, which could be a good revision for some, or an introduction for others :)

working in IT for about 20 years now ... impressively well done video, giving quite an overview for people who have no idea what it is
From my perspective, this video is absolutely great for anyone who’s taken around 2 semesters of CS classes (me lol), as it summarizes almost every concept I’ve learned or heard about until now. For someone who has no idea about IT (me 2 years before), this could be a great introduction, but some concepts might fly over their heads. Nonetheless, this video is definitely the best short format information video amongst others from what I’ve seen. Kudos to the creator
Absolutely direct of a question, but so far have you been making big big money from working in IT?
@@zynthrix barely anyone does .. and since i prefer work life ballance and hate company politics i kept my distance of leadership positions .. i can live quite well with my income but it's definitively NOT big money ^^
It’s Literally my entire first year of CS BSc except the practical parts ofc 💀
Its possible to earn 120000 as an entry salary in the USA when you are good at IT/get through the crazy interviews! So I suppose this is big money.
This coming out less than 11hrs before my CS paper 2 board exam is WILD
Good luck 🤞

Wacky just summed up 5 years of my studies. Having seen this video before, I wouldn't have chosen a computer science school 😂
what would you have chosen instead then?

why
Wait you only covered these during 5 years? Most of this is basically year 1 content.
Not me finishing a 3-year Bachelor in Computer Science, just to be teached everything in 17 minutes by a video on TH-cam 🤡
Was just thinking the same thing but i ll use as quick revision for exams
Does this seriously cover everything? If so, what do you guys do all year?
@@idkmyname2197 the video is more like a global overview of Computer Science, we dive way deeper into the concepts at uni (and we apply them on practical projects)
@@idkmyname2197this is a very surface level video. Think about the iceberg people always use where the tip is above water. Now when applying those things practically, the fun starts. Sounds easy. Looks easy. Not so easy though, and most problems are very situational
You can read and watch videos about cs "stuff", but if you don't do cs "stuff" you will be very surprised at how cryptic and complex these simple topics quickly become. Everything is just so specific, like in coding you have to say EVERYTHING you want the program to do so literally and logically. Missing one semicolon? Program won't function correctly. I wonder how many lines of code are out there missing semicolon? Lol. Like imagine you wrote a program with thousands of lines of code and it won't work because of a small syntax error, or god forbid a logic error that forces you to rewrite half your code, or maybe in this situation for whatever reason it is a syntax error, but instead of throwing an error to you, it's just causing the program to behave incorrectly. You have to sift through this program. You'd think something like that could be automated and while it probably can, your scenerio may be so specific that the automation would need to be modified by you to fit your situation (you don't actually know what situation you are in, remember? You don't know what syntax error or whatever is causing an issue, but you have to test to find it), anyway instead of modifying it at that point you'd be better off manually finding the error. Anyway basically what we do all day is create errors and then try to fix them. As a software developer it's like 50 percent meetings, 5 percent coding and 1000 percent debugging 😂
WACKY SCIENCE WITH ANOTHER BANGER!!!!!!!!!!!!!!!!!
throwing metal into a box is the perfect way to describe my understanding of computers before this video

I took my computer science degree years ago and have been an engineer since. My partner has always shown a vague interest in understanding how computers work but gets easily put off. We taught her a little by playing games like 7 Billion Humans and Turing Complete, but eventually it gets too much. Some minor lightbulb trivia for her that she gets interested in, such as the on/off switch on appliances is just binary 1/0, or sometimes the 1 is intersecting the 0 when it is a single button. Things like that.
So I will send her this video and wish her the best of luck 😅
did it work?
This man gave away more valuable information in a more concise way than 3 of my first semester's classes back then.
Just finished my BS and MS in comp sci here… I’m pretty blown away with this video. Super impressive overview that covers a lot with the perfect amount of detail for people unfamiliar with Cs. You’ve earned a sub
great video! Very helpful and insane how you put every topic together flawlessly!!
My guy is speedrunning through the modules i learn at my university... this is really nice to get overview about what comes in the future and to review old topics again.
Nice vid!
Yeah this is a great refresher.
Wonderful video man, excellent pace covering a lot of information and the depth gone into for each topic is perfect. Amazing job once again!!
Hey Wacky Science,
I just wanted to say that your videos are really amazing! I found some concepts like hardware and operating systems a bit difficult to grasp, especially when you talked about languages and memory allocation. However, your explanation of networking cleared things up for me. I was stuck on that concept for a while, so I'm really glad you covered it. By the way, the Art and Animation in your videos is stunning! Keep up the great work!
Bro just summarised the entire Computer Science background in 16 minutes. This my first ever video i watched of you and I am already a fan!
Dude, I never really understood recursion, but I got it with your great explanation about it with the factorial example. Awesome work.

My entire 4 year B. Tech CSE summarises in this video 😢
Dude, I was taught C++ on a piece of paper.. you don't know what waste of time is xd
That also in 17 minutes 😅
Hey, I've been working as a Software Developer for quite some time now and also do a lot of homelabbing. Your video is really good! You explained the core concepts well and visualized them in a way that it easily understandable for others. I also love that you included machine learning as a topic because it's a recent one compared to the other stuff. Good job!
this was a really really nice video. this opened a couple rabbit holes on software for me to go in
Its always a great day when you upload!!
Wow, you just summarized the whole CS easily. Thanks.
The way you make the sections flow into each other is crazy good
Amazing video, really interesting and intuitive :D
Phenomenal presentation, outstanding simplicity and clarity
Brilliant video and resource
This is very informative, appreciate it
I am in absolute love with your videos, they are humorous and full of knowledge! Please keep up the good work ❤
Bro you have one of the best explanations. Simple yet effective
Great work really appreciated ❤ 👏👏👏
I have no words for how incredible your work is !
I’m afraid of what this guy can find out in a few weeks
arent we all🤣😂
What do you mean?
@@Simple_Info11 if hes doing some thing this great in a short period of time imagine what he would do if he had more time
get it?
Wow. From where to where. You literally told the whole story of computer science in one video :D good job
one of the best videos I watched about computer science
This is a good summary for what I learn from 1/3 of my CS degree.
love how fast you explain.
You can see the channel improvement by each video, fantastic! Loved that awesome thumb
Literally just reminded me to finish my data analysis project
wow, thats so amazing, how you come up with this script that combines everything and yet clear and informative. 🔥
Simple , clear and amazing
cs senior year, and I have to say this was super well put, good job!
Bro is just a few videos in and already has a sponsorship. Keep making awesome stuff. I know this style of video has been working rlly well but remember you can always branch out and do different things (preferably still science, love your explanations)
Great Summary❤
man i really love your videos, combines comedy with education to make my adhd brain understand, never stop uploading man, hope you get more subscribers!
This has already got to be one of the best series in history!
Being a new comp sci student. This video is so incredibly well made and the explanations were so easy to follow! Amazing Job!
Okay, i am intrigued i have sub hope you keep on making more good computer stuff like this .
Small but important correction:
The SQL-Injections are not stopped with replacing
'
with
\'
An attacker could just write:
admin\' --
into the login box. This same program would then replace ' with \' resulting in:
admin\\' --
of which the \\ is interpreted differently and does not escape the ' anymore, thus the injection still works.
If you really want to stop SQL-Injections, you used what is called Prepared Statements.
They are "compiled" with placeholders for the variables, before you ever actually stick any variables into the query.
So when it's time to stick the username and password into the query, the query itself isn't in a text-form anymore and can't be changed or parts commented out.
also fetch, decode and execute arent one cycle, instead fetch is one cycle decode is one cycle and execute is one cycle (though modern cpus have a quite a bit more stages) and you might be confused thinking they all happen one after the other in the same cycle because they do but not one after the other its called pipelineing basicly you make sure all parts of the cpu are at use at all times its kinda hard to explain without a drawing but yeah
@@user-zu6wg9wt8m yeah it's depends upon the instruction how many cycles needs to execute an instruction, he should have to talk about the micro instructions
"Client Side exploit projections always can and will be bypassed. You fool, you moron"
-Sun Tzu, The Art of War
Dude, relax, this video is full of bs. 3 corrections, and I abandoned this idea
@@user-zu6wg9wt8m you are confusing instruction cycles with machine cycles my man. Not the same thing. Also there are architectures that run one instruction per machine cycle.
This video is real gold :D congrats man
i like how this video was able to cover fundamental concepts in computer science (CS).
however, there were other fields in CS that weren't mentioned such as human-computer interaction, parallel computing, automata and formal language theory, computer graphics, software engineering, operating system.
overall, your video is educational, entertaining, and well-explained.
The style of video seem highly inspired from this. its really cool ngl
This was really informative!! Perhaps calculus next? Such as how and why it works
Truly a masterpiece , this literally englobes everything in 17 minutes
Thats a nice introduction video😁
Just adding that the cpu does store data in the form of registers, those are very important in early computer languages, so is probably a good ideia to make a separate video to tackle cpu registers, flags, rings of access, firmware, cpu architecture, virtual memory(the pc in most cases don’t use your actual memory address), virtual machines(Specifically in the context of computer languages)
Don’t know if you left them out on purpose, but hey, just pointing it out 😎👍
Brilliant video I ever found on internet nice work ❤
The fact this guy is able to explain the entire first semester of my CS bachelor's program in such an easily understandable way is incredibly impressive. Awesome video!
This coming out 16 hours before my database management module exam 2 is crazy
Great video! The way computers exactly reads and stores data is often missing knowledge for ppl who didnt study CS but entered the field
Waw a great overview. Thanks
this is genuinely such a good video, gave me flashbacks to my university day lol. can't wait for the next one!
This is a great video. Well done sir. 👏👏
The way this video is structured is amazing, how long did the writing of script take?
This actually really helpful.
dude, this is an incredible video. thx
You are incredible, brother. Best of luck to all your endeavors.
Good but not exhaustive.
You rock !
I really enjoyed your video, you earned a new subscriber. Do you have any suggestions for begginer friendly computer science books?
I love this channel although it has 6 videos good job young man.
You go so fast it almost forces me to memorize as hard as possible, at the same time I now feel like the kid in summer wars(animated movie) when hes calculating things in his head at the end.
5:53 THAT MAKES SO MUCH SENSE NOW! I was wondering why so much of what you do with strings were just the same as with arrays. I thought it was so weird that we designed the languages to give strings all these cool extra properties but it makes so much more sense that the reason strings do a lot of array stuff is because the computer literally stores them as an array of characters.
everything can be displayed as an array, for example, you can take your int pointer, cast it as a character array and print those to the console. the only difference is that strings don't have constant sizes, so you'd need to work with it as an array.
man, i loved your videos (i do not even know how to speak english properly, but bro, this is awesome)
this video blow my mind, it just changed my perspective of computer science!
I'm a computer science professional and I love this video
Thinking about making this vedio as a benchmark for my learning journey.. everytime coming here to see how much I understand with ease 😊
I really liked how you graphically explained that threads give the illusion of concurrency because they context switch so fast
You are doing a great job! Thanks
Maybe next video about biology?
This is Brilliant ❤
Yooo been waiting for this one to drop 🔥🔥🔥🔥
Great work
subscriber acquired. I've been wanting this knowledge for so long...
I love these videos
The best explanation I've ever heard throughout my entire CS course
amazing video , i'm a student in germany and my school is focused in Computer science and i do it like 6 years and thought i do crazy shit, and you explained it in just 17 minutes. It's incredible. I like your video so much 👍🏿 a subscribe and a like is a must have
Detailed and informative - now I get to go watch it 10 more times to remember everything lol
I'm graduating my cs program in a few weeks and this basically sums up my first few years of Uni
Holy Shit, the transitions from one topic to another is so smooth, I loved it!
Cool revision video
I found this video really very helpful Sir please upload more videos related to computer science ❤❤
Damn, informative as always!
Very accurate and fun to watch. 👍
nice one mate, sick vidya
You've just made my life better
pure gold. very well compressed and structured overview.
U earned my subscription 👍
you really had to release this the day after my computing exam
Keep creating your videos, they will go viral
You are very very good at it
