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
@@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 ^^
For everyone stressing about how they wasted four years learning what he just summarized into 16 minutes calm down you were only able to understand him because you spent 4 Years Learning what he's explaining. A normal person can only understand the first 5 minutes or so, I even started watching the video at .85 speed and I'm still learning and forgetting everything he's teaching within seconds. This video is cool but past the first 5 minutes it can only be truly appreciated by people who already know most of what he's teaching
@@twilightofpeace-q3cyou're not exactly disagreeing, you just implied it took you years to learn things which means this video can not replace the years aspect of it
@@RoyHoy That's not the point of the video though, It's just a review + a big picture of what you are going to learn when you properly study CS in the college
bro casually explained everything that took me 5 years to understand, in one video and explained it better than my teachers with decades of experience, why did i even went to college
Connections and societal approval. We don't go to college to learn stuff anymore. We go because everyone around us told us to go. Also, it just so happens that a lot of smart people getting together in one place tends to make things happen. Those connections are useful later on.
@@equinox-XVI Also, back then i didn't understand most of these concepts as long as you pass the test it doesn't matter, wasted so much time and energy, and we didn't use most of it
If I suppose your college wasn't absolutely horrible, it's likely you wouldn't understand this video witout the classes. Or you understand these topics in a much greater depth than what this video offers.
@@NervylHraje The education system in my country is just garbage, we rely on theory more than practice, and it doesn't matter if you understand what you study, all that matters is the grades you get in the end, even though I had great grades, but I only understood these topics, only during a vacation where I spend time out of curiosity, teaching myself just from youtube, and books, but during the years I had to turn my brain off, and just memorize theories and concepts, without a clue what and why the heck am studying this.
We go to actually learn the stuff. It's one thing to know but understanding takes practice. But yeah, ideally college should be optional but it's how stuff work in the world
Well it's not really full information that you need to know, but I think it's at good level. Anyway , I am sorry to know that you had hard time when you were learning it, because of teacher
Not gonna lie. If lectures were structured like this and include tons of Memes, instead of paragraph long of text popping up in the screen and boring conversations. I would have no problem at learning in the first place. lol.
There isn't a specific code, but rather a combination of factors that law enforcement and criminologists use to profile and identify serial killers. These include: 1. Behavioral patterns: - Modus Operandi (MO) - Signature behaviors - Ritualistic actions 2. Demographic characteristics: - Age, gender, race - Socioeconomic status - Education level 3. Psychological traits: - Personality disorders (e.g., psychopathy, narcissism) - Mental health issues (e.g., depression, anxiety) - Cognitive distortions 4. Crime scene indicators: - Type of crime (e.g., homicide, arson) - Location and geography - Victimology (victim characteristics) 5. Investigative psychology: - Criminal profiling - Behavioral analysis - Investigative psychology models (e.g., Crime Scene Assessment Model) Some specific codes and tools used in profiling serial killers include: 1. The Macdonald Triad: a set of three childhood behaviors (animal cruelty, bedwetting, and firesetting) that may indicate potential for violent behavior. 2. The Psychopathy Checklist (PCL): a tool used to assess psychopathic traits. 3. The FBI's Crime Classification Manual: a system for categorizing crimes and identifying patterns. Keep in mind that profiling serial killers is a complex task that requires extensive training, expertise, and collaboration between law enforcement, criminologists, and mental health professionals.

To everybody who keep saying what’s the point of you going to college when a 16:49 video covered everything and helped you understood, I am a complete beginner and I understood only the first 5 minute, but was still a fun run watching 😂😂😂 so no, ur college is not useless. This video definitely got my interest to learn more tho🤓
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
Keeping in mind everything that was explained here was super high level for each topic. It was an excellent peek into how things work for those who are curious and people dedicate their entire carreer to just one segment.
@@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 😂
@@idkmyname2197 in the video he goes over finding the shortest path like google maps. Sounds easy right? He talks about algorithms, which is a set of instructions. In my course we had to implement an algorithm to actually find a short path between 2 places. It's impossible currently to actually find "the shortest path" for anything sizeable because the algorithm would have big O(n!) which is insanely big. For 25 destinations, you have 15511210043330985984000000 paths to check. That course took me about 6 weeks. Covering intro to Python, then algorithms (including heuristics which gives approximate solutions), then big o, then the task. Every topic he glosses over can be expanded similarly for many other courses. Try making your own linked list and then reordering it, try to use your linked list to make a queue, then try it with a stack. It goes on and on.
He summarised the last 4 years of my education and I feel angry and frustrated, and immensely impressed. If you are interested in the area but do not wanna go to uni, study and search each concept and sentence in this video.

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!
12:16 I’m a Technical Recruiter for a FinTech company that often recruits for Software Engineer roles. I am loving this video. The ML section is perfect for a quick breakdown for people. 👌🏾
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!
I'm amazed that you summarized all the important concepts in computer science in under 17 minutes and managed to stay both cohesive and easily understandable! This was simply amazing
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 😅
I would like to express my sincere gratitude for this resource. It has been instrumental in bridging the gap between my two years of computer science education and my current understanding of the field. During my depression, I struggled to grasp the concepts I had learned previously. However, after transitioning to finance and specializing in derivatives and risk management, I have gained a profound comprehension of the intricacies of computer science. I am deeply appreciative of this resource and its ability to enhance my knowledge and understanding.
One of the best videos ive seen. This really pushes me foward to finish my ingeniering major even though is hard and frustrating. From the flawless simple explanation to the humor and editing skills i really wanted to say this is the best video ive seen at least this year. Amazing👏
Amazing video man, you just culminated in one video what I learned over 4 semesters of my cs degree from the top computer university in my country. props mate, do more of these man.
I just graduated with a B.S. in computer science less than a month ago and I wish I could’ve seen this video 4 years ago. Absolutely impressive how well you tied everything together and explained it so clearly and concisely.
2:10 modern cpus actually have registers and cache memory in them. both are very high speed forms of memory. registers are used for calculations, they get loaded with values from ram, the cpu performs calculations on them and the result can be put directly back to ram. cache memory simply caches frequently used values from ram since from the cpu reading from ram is kinda slow, so the cache speeds things up
I already knew a lot of these concepts, but I never made the connection between them until now. We were never taught how all of this is interrelated, and right now, I’m honestly blown away by the information you provided. Thank you!
everyone can explain a topic going deeply and include all sorts of complicated stuff that may not be understable to everyone! but to simplyfy the topic and compile the information and make it digestable so, that everyone can learn ! that's a real job cause they help a lot of begginers to start their journey, bro you have no idea how many people you are helping through your videos ! great work and really appreciate your effort in these videos
2:07 dude. this is the BEST description of a cpu ive every heard "the cpu follows instructions like a genius, but has the memory of a demented goldfish"
You had me at 'you could write the code in binary but you'd go crazy'. Reminds me of the way I learned to code by typing in the hex numbers from the instruction set of the commodore 64.
As someone who has almost no knowledge about computers, This is the first video that i had to watch in slow motion to understand things. Today i learned something good! Thank you for making such quality videos!👍👍😊😊❤❤
I’ve never took any comp sci classes but I love to learn and I stumbled upon this video I feel everything went in one ear and out another but I’m so intrigued
Your videos are all an absolute MASTERPIECE. I work in IT and i just used this video to explain hours of stuff to a friend that is thinking about choosing a area in IT to study Thank u Wacky!!
The way he explained all this in an incredible small amount of time linked all the concepts of 3years of CSE Course in college ( love from INDIA -Uttarakhand).
I’m so happy I found this video. I’ve been thinking of doing Computer Science at my local University. It’s 3 years, so it’s a long commitment and I wanted to know what the heck I’d be getting myself into. This has given me a great idea - thank you! Just for reference, what are some of the main paths you personally know you can take after learning Computer Science.
man i have to be honest, this is the best video for learning computer science out there, im a dev and i was having so much trouble fully understanding computer science but i spent 17 minutes on this video and dont need to learn anything else. thank you
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!
i always was so confused about wth actually a computer really is, how it works and the internet... and while im still far from actually understanding it this video helped SOOOO much to understand the basic concept and clear up the important information. youre a hero, amazing video!
This video is perfect, I want to start with computer science, but I had no idea where to start, now I have at least a starting point, even tough I'm still not really sure where I should start explicitly. But one important note I do have to make, if something hast to do with a flamingo, I need to start with this
you might start with programming. Although it might sound a bit too much to start, you will quickly learn the programming thinking and you will automatically start to understand how things work. When you don't know how something works, you can search and slowly you'll be learning everything related. I don't recommend languages like C or C++ because you might get stuck on irrelevant things like syntax. Instead I recommend some easier languages like python, although python might be too simplified to have a good understanding of programming. Maybe a good language to start with could be javascript, and you would also have knowledge to start building websites in the future if you like that.
0:12 - Yeah that's not just silicon, It's doped with other substances to make it act like an semi-conductor. 1:46 - A kernel is different from operating system, an OS is built on top of kernel, Window's Kernel is "Windows NT Kernel" and Linux is infact a kernel and OSes built on top of Linux are called Linux Distributions or Linux in short, and Mac's Kernel is "XNU" or "X is Not Unix". 2:42 - Also 2GHz doesn't mean a CPU would execute 2 Billion instructions per second, that is because ALOT of instructions take more than 1 clock cycle to execute a instruction. 4:42 - Not only static typing avoids bugs, but It MASSIVELY improves performance because in dynamically typed languages there's a always a overhead of keeping track of the type of variable and it's size. 4:54 - Also This "chunk" of memory is of known size, on a 64 bit machine a pointer is 64 bytes, on a 32 bit machine a pointer is 32 bytes, that's why a 32 bit machine can only work with upto ~4GB of RAM because the maximum size of address the CPU can work with is 2^32 or 4,29,49,67,296. 5:07 - Also stack is fixed size which makes it faster to access, but if you need chunk of memory you know size of at runtime, you have to use "heap", but just know that heap and stack both exist in RAM, it's just that stack is faster due to it's fixed size. 5:21 - A memory leak can't slow down a process BUT it can crash because you will run out of RAM if you keep leaking the memory. ALSO If your program exits, all the memory is just reclaimed by the kernel, so memory leak is just an issue for a process's lifetime, not after it. 6:14 - You can always resize the array to fit the elements thus not wasting memory, but using Linked list to solve this "issue" is an even worse solution because linked-lists use much more memory than an usual array and are slower to access. 8:55 - At the machine code level, when you call a function you jump to it but then you have no clue where you have to go after the function completes, so the call stack just holds the address to return to after the function finishes. 9:11 - Here, '!=' is an equality operator called "not equals to", a not operator is a single exclamation mark and it only _operates_ on a single value. Great Video Overall, Perfect for beginners.
This touches nearly every field in computer science. Except cryptography and operating system development and scheduling. It did not cover hardware development and microchip programming (like VHDL), but since it touched on logic gates and gatter I let it count. I do like the definition of machine learning though. That was elegant. Very well done.
Omg this video is perfect, I havent seen a cleaner video about computer science in my entier life. Bro just teached me 2 years of my college lessons in 17 minutes.
This is incredibly helpful, I’ve always been scared of computer science, this actually explains what software does in relation to hardware and how they interact which is rather rare.
My years of computer science and electronics engineering knowledge covered in 17 min…good work….really a great video for people who just know coding and didn’t understand what happens under the hood
you’d be surprised how basic all of this actually is, you’d learn pretty much all of this with greater depth in your first semester of computer science in post secondary
OH COME ON!! YOU HAVE GOT TO MAKE MORE OF THESE VIDEOS PLEASSEEE HUMANITY NEEDS THIS I used to pretty much hate computer science merely because of how miserably it was taught to us in school so this comes as a godsend and now im definitely learning programming Love your videos so so much

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!
I seriously believe you are a top 10 youtuber right now

Did you intentionally double the Zs, or is it the actual spelling?
@@OnkarPawar00 what double Z's

the way you dissect complex topics is awe-inspiring!
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!
12:16 I’m a Technical Recruiter for a FinTech company that often recruits for Software Engineer roles. I am loving this video. The ML section is perfect for a quick breakdown for people. 👌🏾
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.
I'm amazed that you summarized all the important concepts in computer science in under 17 minutes and managed to stay both cohesive and easily understandable! This was simply amazing
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?
Yeah did it?
Would be good to know
Any updates? 😂
Bro just explained my 4 years of hard work like nothing 😢
9:22 Damn the "loop over, loop over, loop over" got me. Nearly spilled my energy drink.
I would like to express my sincere gratitude for this resource. It has been instrumental in bridging the gap between my two years of computer science education and my current understanding of the field. During my depression, I struggled to grasp the concepts I had learned previously. However, after transitioning to finance and specializing in derivatives and risk management, I have gained a profound comprehension of the intricacies of computer science. I am deeply appreciative of this resource and its ability to enhance my knowledge and understanding.
bro is speaking 10 facts a second, great video!
One of the best videos ive seen. This really pushes me foward to finish my ingeniering major even though is hard and frustrating.
From the flawless simple explanation to the humor and editing skills i really wanted to say this is the best video ive seen at least this year.
Amazing👏
Literally just reminded me to finish my data analysis project
Amazing video man, you just culminated in one video what I learned over 4 semesters of my cs degree from the top computer university in my country. props mate, do more of these man.
I just graduated with a B.S. in computer science less than a month ago and I wish I could’ve seen this video 4 years ago. Absolutely impressive how well you tied everything together and explained it so clearly and concisely.
Is it hard to get a remote job in this field?
2:10 modern cpus actually have registers and cache memory in them. both are very high speed forms of memory. registers are used for calculations, they get loaded with values from ram, the cpu performs calculations on them and the result can be put directly back to ram. cache memory simply caches frequently used values from ram since from the cpu reading from ram is kinda slow, so the cache speeds things up
This coming out 16 hours before my database management module exam 2 is crazy
I already knew a lot of these concepts, but I never made the connection between them until now. We were never taught how all of this is interrelated, and right now, I’m honestly blown away by the information you provided. Thank you!
I'm a computer science professional and I love this video
everyone can explain a topic going deeply and include all sorts of complicated stuff that may not be understable to everyone! but to simplyfy the topic and compile the information and make it digestable so, that everyone can learn ! that's a real job cause they help a lot of begginers to start their journey, bro you have no idea how many people you are helping through your videos ! great work and really appreciate your effort in these videos
Omg, you are connecting all the pieces together. Thank you
2:07 dude. this is the BEST description of a cpu ive every heard
"the cpu follows instructions like a genius, but has the memory of a demented goldfish"
Wow, you just summarized the whole CS easily. Thanks.
You had me at 'you could write the code in binary but you'd go crazy'. Reminds me of the way I learned to code by typing in the hex numbers from the instruction set of the commodore 64.
great video! Very helpful and insane how you put every topic together flawlessly!!
As someone who has almost no knowledge about computers, This is the first video that i had to watch in slow motion to understand things. Today i learned something good! Thank you for making such quality videos!👍👍😊😊❤❤
I’ve never took any comp sci classes but I love to learn and I stumbled upon this video I feel everything went in one ear and out another but I’m so intrigued
Your videos are all an absolute MASTERPIECE.
I work in IT and i just used this video to explain hours of stuff to a friend that is thinking about choosing a area in IT to study
Thank u Wacky!!
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?
The way he explained all this in an incredible small amount of time linked all the concepts of 3years of CSE Course in college ( love from INDIA -Uttarakhand).
As a Computer science engineer
This is it .
Keep it up
👍
I’m so happy I found this video. I’ve been thinking of doing Computer Science at my local University. It’s 3 years, so it’s a long commitment and I wanted to know what the heck I’d be getting myself into. This has given me a great idea - thank you!
Just for reference, what are some of the main paths you personally know you can take after learning Computer Science.
on the same page bro
This is a good summary for what I learn from 1/3 of my CS degree.
You summed up an INCREDIBLE amount of data and learning exquisitely! Nice job!!
Wonderful video man, excellent pace covering a lot of information and the depth gone into for each topic is perfect. Amazing job once again!!
man i have to be honest, this is the best video for learning computer science out there, im a dev and i was having so much trouble fully understanding computer science but i spent 17 minutes on this video and dont need to learn anything else. thank you
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!
so if this is your first sem whats in the second sem. Bro he literally explained the whole computer science with one overview video this is nuts.
i always was so confused about wth actually a computer really is, how it works and the internet... and while im still far from actually understanding it this video helped SOOOO much to understand the basic concept and clear up the important information. youre a hero, amazing video!
13:03
"The internet is not a big truck, it's a series of tubes"
you summarized what I have been studying for two years in my course in less than 20 minutes. Amazing.
Its always a great day when you upload!!
Now THIS is content I need, crazy how you’re doing all this young. Keep going man, the world needs more nerds.
best video for computer science engneering students . thank you for given great Knowledge about computer👌✨️
This was such a clear explanation. I’ve been working to understand binary for a long time and finally a lightbulb went off. Thank you!
2:50 dunno if it’s a typo but it’s a fun one😂
I'm a computer science junior and I guarantee this is the best video on youtube about it
This video is perfect, I want to start with computer science, but I had no idea where to start, now I have at least a starting point, even tough I'm still not really sure where I should start explicitly. But one important note I do have to make, if something hast to do with a flamingo, I need to start with this
🦩
@@wacky.science HTF you managed to do that
you might start with programming. Although it might sound a bit too much to start, you will quickly learn the programming thinking and you will automatically start to understand how things work. When you don't know how something works, you can search and slowly you'll be learning everything related.
I don't recommend languages like C or C++ because you might get stuck on irrelevant things like syntax. Instead I recommend some easier languages like python, although python might be too simplified to have a good understanding of programming. Maybe a good language to start with could be javascript, and you would also have knowledge to start building websites in the future if you like that.
I needed this. Im going to take computer science and cybersecurity fundamentals this year. Hopefully this gets me prepared for whats to come
0:12 - Yeah that's not just silicon, It's doped with other substances to make it act like an semi-conductor.
1:46 - A kernel is different from operating system, an OS is built on top of kernel, Window's Kernel is "Windows NT Kernel" and Linux is infact a kernel and OSes built on top of Linux are called Linux Distributions or Linux in short, and Mac's Kernel is "XNU" or "X is Not Unix".
2:42 - Also 2GHz doesn't mean a CPU would execute 2 Billion instructions per second, that is because ALOT of instructions take more than 1 clock cycle to execute a instruction.
4:42 - Not only static typing avoids bugs, but It MASSIVELY improves performance because in dynamically typed languages there's a always a overhead of keeping track of the type of variable and it's size.
4:54 - Also This "chunk" of memory is of known size, on a 64 bit machine a pointer is 64 bytes, on a 32 bit machine a pointer is 32 bytes, that's why a 32 bit machine can only work with upto ~4GB of RAM because the maximum size of address the CPU can work with is 2^32 or 4,29,49,67,296.
5:07 - Also stack is fixed size which makes it faster to access, but if you need chunk of memory you know size of at runtime, you have to use "heap", but just know that heap and stack both exist in RAM, it's just that stack is faster due to it's fixed size.
5:21 - A memory leak can't slow down a process BUT it can crash because you will run out of RAM if you keep leaking the memory. ALSO If your program exits, all the memory is just reclaimed by the kernel, so memory leak is just an issue for a process's lifetime, not after it.
6:14 - You can always resize the array to fit the elements thus not wasting memory, but using Linked list to solve this "issue" is an even worse solution because linked-lists use much more memory than an usual array and are slower to access.
8:55 - At the machine code level, when you call a function you jump to it but then you have no clue where you have to go after the function completes, so the call stack just holds the address to return to after the function finishes.
9:11 - Here, '!=' is an equality operator called "not equals to", a not operator is a single exclamation mark and it only _operates_ on a single value.
Great Video Overall, Perfect for beginners.
🤓
Awesome, you literally gave away the basics of computer science, programming and the internet, in 15 minutes
This touches nearly every field in computer science. Except cryptography and operating system development and scheduling. It did not cover hardware development and microchip programming (like VHDL), but since it touched on logic gates and gatter I let it count. I do like the definition of machine learning though. That was elegant. Very well done.
i agree
Is not VHDL part of CE? Not CS?
@@crobatgaming5661 depends, it seems to appear in both. I studied Computer Science and we had to finish courses for it.
This was a really good video given the concepts covered, the way it's explained and the time of course. Great overview of a lot of topics
This Video >>>> My 4 years of a Computer Science Degree
Finally! Someone who speaks understandable English and not a bot. Its so hard to find that looking for computer information
pure gold. very well compressed and structured overview.
As an up-and-coming sophomore stem student, this video has had my brain feel overloaded and frankly made. Great video, man
You've just made my life better
Omg this video is perfect, I havent seen a cleaner video about computer science in my entier life. Bro just teached me 2 years of my college lessons in 17 minutes.
YOU did a fantastic work!
If you can do the same thing to "Electrical Engineering" would be amazing.
Thanks.
This is incredibly helpful, I’ve always been scared of computer science, this actually explains what software does in relation to hardware and how they interact which is rather rare.
I just summerized my whole degree in 17 minutes
My years of computer science and electronics engineering knowledge covered in 17 min…good work….really a great video for people who just know coding and didn’t understand what happens under the hood
HECK YEA MAN
Never thought twice about subbing xD
agreed
Just this straight-to-the-point material! Knew most of it but the explanation clarified much of it.
Why do I even go to school when this exists
As a computer science engineer in college, I will be referencing this video for the rest of time. Thank you sir
This is Brilliant ❤
Thanks to this video I'm now a computer scientist. I will put this in my resume.
Bro fried all of my last 3 brain cells💀💀
you’d be surprised how basic all of this actually is, you’d learn pretty much all of this with greater depth in your first semester of computer science in post secondary
man this is crazy funny and at the same time informational. You did an absolute great job in conveying information with entertainment!
2:50 over what?
Overclock*
I'm a second year Software Engineering Student and Part time front end developer, you just summarized my last two year!
Wacky science is back..!!!
OH COME ON!! YOU HAVE GOT TO MAKE MORE OF THESE VIDEOS PLEASSEEE
HUMANITY NEEDS THIS
I used to pretty much hate computer science merely because of how miserably it was taught to us in school so this comes as a godsend and now im definitely learning programming
Love your videos so so much
That is my entire CS minor degree summarized in 15 mins.
