Excellent Video on the topic of Abstraction. Even as a developer there are so many abstractions, abstractions like protocols, operating systems, back-end/front-end Frameworks. Often times it gets difficult to filter out what is relevant and what is not. And yes go deeper into the topic.
a few moths ago i saw a lecture about fundamentals of c++ and the teacher said when we are creating a variable we are abstracting a memory address his words kept looping in my head and i never understood what did he mean with that but now after watching the half of your video it clicked in my head and it start making sense "when we create a variable we are actually abstracting a memory address" thanks for the amazing explanation
Yes please talk more about the topic when is a useful abstraction and when is an error, now in my company we have an abstraction that I think is harder to understand than useful but the tech lead thinks different so more about the topic would be really useful
this is understandable for ppl who studied programming. for a general public audience, they may not have to know the compiler part explanation or use the switch to explain, juz simply tell them abstraction means a template apply on many other code may be fine
so in other words abstraction is basiclly to hide codes o programing fuctiones , that allows the user to work more efficiently in the programing process , very interesting. for one moment I thought that the definition would be more complicated. thanks for the video it really helped a lot
Thanks for the efforts making in this video . It was a really so helpful to understand abstraction . This video makes the information so easier than academic research.
Hi I'm trying to understand what is High Level and Low Level Abstraction. In the video at 5:13 is "postToSocialMedia function" High Level Abstraction? Thanks I enjoyed watching this video. You put the fun into complex programming.
Bits Represent Signal Measurements Those Signals Are Measured Using Math, The Purpose of Using Bits Rather than Alternatives Is Because of a Math Problem Regarding Advance Algorithms & Errors
but I have a question ? if an abstraction is a layer that hides codes of programing fuctions , the programmer developer would have to create it right ?
Just a correction and modification of some concepts ------- Abstraction is not that concept of showing or providing only the important things and hiding all unnecessary or complex details from the user (the programmer), as everyone thinks You kindly explained that Abstraction is to provide only what the user can get, in short, to provide only the Important points in the classes that will be instanciated using an Object, and this is unfortunately wrong.... And if it was actually in this sense, the name would have been Only-Important-members or Hidding Data and so on... --------- In short, your concept is part of the definition of Encapsulation and not Abstraction, and it is very close to the concept of inheritance more than Encapsulation --------- Linguistically: Abstraction means intangible or imaginary or virtual or the opposite of Concrete which means tangible, real or active --------- Programmatically: It specifically means the Class and the Interface (interface is not available in all programming languages). The important thing is the Class in itself. And any Class in OOP is considered as a Template, Model, or Map of something in Reality. That thing may be real or imaginary, and as it may be tangible or intangible, it does not matter the Projection and how .... but it matters The Classes that will Ultimately Express an Entity, Component, or Object that we will deal with later.... -------- So Abstraction in OOP will be like that: Modeling the Real World. and No more than this Definition .. -------- There are also inactive, intangible, or Abstract Classes that we call them Class Model, and they are somewhat similar to the Interface. This type has a directive of type Abstract and it does not accept instanciate with Objects, that is, it has no Objects to represent it (No Instances). And her task is Only to make a Model or Template for her children's that inherited from and finally can share members from base Abstract Classe. And this technique is also within the definition of the corner Abstraction And my concept here is in modeling and not in the role of the abstract class (because its role in terms of providing only what the sons classes can share as members and this is a part from the corner of inheritance) finally : Abstract classes is an Abstract Model for a Concrete classes Where this concrete will be a Models for some objects in our Real World... -------- Interfaces are also a Model or Abstract that Classes use them in-order to benefit from those members in that Interface.. So, Abstraction OOP is only about these three things in C Sharp, Java and Delphi and maybe C++ builder(because all of them have Interface as far as I know now) ------ As for the definition that you explained in the video, it is related to Encapsulation and Inheritance rules and not Abstraction at All .. ----- Abstraction is the first Step Rule of OOP Pillars wich is the Classes and Interfaces ... Abstraction is not more than a Modelling ... ----- And thank you for your understanding ...
I think that was one of the best explanations of abstraction that I have seen. And I'm a programmer for about 10 years :) Good job!
I LOVE U!!! LITERALLY THE BEST, SIMPLE, STRAIGHT FORWARD DEFINITION EVER!!!!!

Excellent explanation and examples. Thank you for making this video!
Thank you!
Excellent Video on the topic of Abstraction. Even as a developer there are so many abstractions, abstractions like protocols, operating systems, back-end/front-end Frameworks. Often times it gets difficult to filter out what is relevant and what is not. And yes go deeper into the topic.
Well done, and entertaining! Thank you for the info and the interesting presentation style. (Loved the elevator interruptions. XD )
Very good! I knew a lot about abstraction in computer science, but you sumed it up nicely! Thanks
The elevator interruption made me laugh out loud. Well done, excellent video.
a few moths ago i saw a lecture about fundamentals of c++ and the teacher said when we are creating a variable we are abstracting a memory address his words kept looping in my head and
i never understood what did he mean with that but now after watching the half of your video it clicked in my head and it start making sense
"when we create a variable we are actually abstracting a memory address"
thanks for the amazing explanation
Missed your videos! Good to have you back.
Thanks! Trying to get back on track.
I had been struggling with this concept wise and i am happy that I have clear understanding, Thank You
Yes please talk more about the topic when is a useful abstraction and when is an error, now in my company we have an abstraction that I think is harder to understand than useful but the tech lead thinks different so more about the topic would be really useful
Holy shit, my man u made everything so easy to understand. I thought this whole thing was way more complicated, but i guess not anymore. -CS Student
Awesome video, very well structured and animated. Congratulations!
you explained it perfectly. very good balance between jokes and explanation
You have done a good job!...Thank you. You should post another video on the details of abstraction.
deeper please :) and thank you
Thanks! Will go deeper soon.
this is understandable for ppl who studied programming. for a general public audience, they may not have to know the compiler part explanation or use the switch to explain, juz simply tell them abstraction means a template apply on many other code may be fine
I would love to see a video that goes deeper into the topic, thx for sharing this one already.
This channel is just epic, love it

BEST EXPLANATION THIS WILL HELP ME ON MY AP EXAM
Outstanding video, very clear and engaging - thanks!
One caveat only - these are not illusions, these are representations. Very different concepts.
That definitely abstracted abstraction for me-thanks!
so in other words abstraction is basiclly to hide codes o programing fuctiones , that allows the user to work more efficiently in the programing process , very interesting.
for one moment I thought that the definition would be more complicated.
thanks for the video it really helped a lot
Great explanation. Interested to know more!
Thanks for the efforts making in this video . It was a really so helpful to understand abstraction . This video makes the information so easier than academic research.
Very useful. You deserve more subscribers.
Yo this video is shown on the AP COMP SCI course for UC scouts
Nice! Is the curriculum available somewhere?
@@rakhimd.5703 Yea, but you have to pay like $400 for it, it's only really for students who need GPA boosts or AP courses
This was extremely simple to understand, thanks to you.
This was perfect. Keep up the great work. Thank you so much.
Scam
2:08
This is so true, thank you.
Best video on abstraction I've seen, thank you very much. Does anyone know if he made a deeper dive video? Can't see one but would love one.
U absolutely need more subs. Here i give you one
Thanks I find this a breathaking view of abstraction without the academic jargon I always saw in the books
Great explanation with nice examples
Bro. This is so goooood. Thanks for the explanation!!!
Great Explanation.. thank you, really made sense of this to me
Hi. I was wondering what is considered a predefined abstraction. In scratch, are the purple blocks a predefined abstraction?
Perfectly explained! thank you for this!
This was such a good video! Thank you so much!
Very good explanation on this topic!
Man you didnt just make me think about cs but about life too, wow thank you!
This is a fantastic explanation imo
DID HE EVER GO DEEPER INTO THE TOPIC?
Also, lol at being interrupted by the elevator, great info with great humor haha.
This was awesome. Thank you!
This was a very helpful vid, thank you.
Great video... Thank you so much!
Thank you for share!
Well explained, thanks
Hi
I'm trying to understand what is High Level and Low Level Abstraction.
In the video at 5:13 is "postToSocialMedia function" High Level Abstraction?
Thanks
I enjoyed watching this video. You put the fun into complex programming.
thank you, it was a very well explained video. Good Job!
Hi, can you recommend books on this topic?
This was so helpful, thank you!

great explanation
1:20
him: i will now proceed to deny the elevator it's existence
elevator: no
fr tho, nice video, thanks
arguing with the elevator was so funny
Nice explanation
great video! LOVED IT!!!!
Thank you for this
but I have a question ? if an abstraction is a layer that hides codes of programing fuctions , the programmer developer would have to create it right ?
Thanks for the video
thank you very much!
Thanks, man!
thank you, helped me a lot!
Thank you!
You have earned a sub!
Best explaination so far I found on youtube, thank God you saved me from indian videos ( sadly with no expaination/examples).
Great video
Awesome. Thanks
thank you man you are great
Beautiful!
This was great.
Rip to those got lost in "abstractions in OOP's" while trying to find this topic
Oh my gosh I'm glad I did not show my class this video. You are funny but I can't show that in school haha
Could you elaborate please? :-) I could make a PG-13 version kind of thing...
@@Codexpanse 1:30 lmao
Where the Digital Circus fans at
They aren’t illusions. The relationships actually exist in reality!
👍
alright, abstraction makes sense, bug polymorpism or whatever is called

FIRST COMMENT BABY!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Did you like the video though? :-)

Just a correction and modification of some concepts
-------
Abstraction is not that concept of showing or providing only the important things and hiding all unnecessary or complex details from the user (the programmer), as everyone thinks
You kindly explained that Abstraction is to provide only what the user can get, in short, to provide only the Important points in the classes that will be instanciated using an Object, and this is unfortunately wrong....
And if it was actually in this sense, the name would have been Only-Important-members or Hidding Data and so on...
---------
In short, your concept is part of the definition of Encapsulation and not Abstraction, and it is very close to the concept of inheritance more than Encapsulation
---------
Linguistically:
Abstraction means intangible or imaginary or virtual or the opposite of Concrete which means tangible, real or active
---------
Programmatically:
It specifically means the Class and the Interface (interface is not available in all programming languages). The important thing is the Class in itself.
And any Class in OOP is considered as a Template, Model, or Map of something in Reality. That thing may be real or imaginary, and as it may be tangible or intangible, it does not matter the Projection and how .... but it matters The Classes that will Ultimately Express an Entity, Component, or Object that we will deal with later....
--------
So Abstraction in OOP will be like that:
Modeling the Real World. and No more than this Definition ..
--------
There are also inactive, intangible, or Abstract Classes that we call them Class Model, and they are somewhat similar to the Interface.
This type has a directive of type Abstract and it does not accept instanciate with Objects, that is, it has no Objects to represent it (No Instances).

And my concept here is in modeling and not in the role of the abstract class (because its role in terms of providing only what the sons classes can share as members and this is a part from the corner of inheritance)
finally :
Abstract classes is an Abstract Model for a Concrete classes Where this concrete will be a Models for some objects in our Real World...
--------
Interfaces are also a Model or Abstract that Classes use them in-order to benefit from those members in that Interface..
So, Abstraction OOP is only about these three things in C Sharp, Java and Delphi and maybe C++ builder(because all of them have Interface as far as I know now)
------
As for the definition that you explained in the video, it is related to Encapsulation and Inheritance rules and not Abstraction at All ..
-----
Abstraction is the first Step Rule of OOP Pillars wich is the Classes and Interfaces ...
Abstraction is not more than a Modelling ...
-----
And thank you for your understanding ...
You should go more deeper sir
I feel like if Oberin Martell was teaching me computer science which is great
But... I like my eyeballs!
Well let’s pretend that he killed the mountain and that didn’t happened hahaha
