I have question: First programing language is written by hand, such as punch card and detect digital signal by holes on card or manually open close switches. Based on manually open close switches, they convert into abstraction as "mov" "add" in paper sheet? And why binary as text abstraction can generate electrical sign to interact with hardware
Great question. In the early days, computers used punch cards or switches to input instructions. Each hole or switch represented binary (1s and 0s) that the computer could understand. To make things easier for humans, languages like Assembly were created. Instead of flipping switches, you could use commands like 'mov' or 'add' which are easier to write and read. These commands are then translated into binary (1s and 0s) that the computer's hardware can process as electrical signals. Think of Assembly like a bridge: you write in a simple language and it gets converted into the binary code that the computer uses to control its hardware.
@@WhiteboardDoodles24 the key matter is that by which mechanism the computer can process binary as electrical signals Which method convert from abstraction text to physical interaction?? As punch card, they have sensor or smth to detect holes by light
The key mechanism here is that computers work by detecting electrical signals. A '1' in binary represents an 'on' signal (a flow of electricity), while a '0' represents an 'off' signal (no flow of electricity). These signals travel through the computer's circuits to perform tasks. In modern computers, the CPU (central processing unit) processes these binary instructions. When you write Assembly code, the computer translates that into machine code (binary). The CPU has transistors, which act like tiny switches. These transistors can be turned on or off, representing 1s and 0s in binary. The sequence of binary instructions tells the transistors how to process data, perform calculations and interact with the hardware. As for punch cards, you're right - they had sensors that could detect holes. The holes represented binary 1s and 0s, which the computer's hardware would process similarly, by sending electrical signals based on whether a hole was detected or not. So, to summarize, the CPU processes binary by using electrical signals and transistors act as the switches that execute instructions based on those signals.
@@WhiteboardDoodles24 tks but it's still not clear how hardware detect text abstraction from series of 0 or 1 For example, when you press the key on teleprinter, it close the switch and connect to hardware circuit for other processing But when you type mov r1, r2, r3, it is translated into binary code. But it is still an abstraction from screen, it need a "sensor" in order that computer hardware could realizes it is 0 or 1 to do on/off electricity So, what's kind of sensor and machanism? It need to be logic comparing to hard drive when data is retrieved from magnetic and non magnetic as 0/1 on surface..but in assembly ..series 0/1 from mov/load/add instruction is detected via I/O as keyboard?
@@maxmuster7003both these languages have implied registers. So you write down the instructions and then insert some moves to match. Important instructions like add, load and store work on all registers, I think. Now I may have to look up if encoding is more difficult for AX than for AL, AH. Why not check the flags after AND ?

Great question! Yes, Assembly language can be used for mobile devices, but it depends on the processor architecture of the device. For example, ARM Assembly is commonly used for mobile devices since most smartphones and tablets use ARM-based processors. However, writing Assembly for mobile devices is rare in modern app development because higher-level languages like Swift, Kotlin and C++ are more commonly used for efficiency and portability. Thanks for asking!
Great question! Assembly language gives you direct access to the hardware, allowing you to do things like: - Manipulate specific CPU registers - Write highly optimized, low-level routines - Execute precise timing operations - Interact directly with memory addresses While higher-level languages abstract these details for ease of use, Assembly is unmatched when you need fine-grained control over how your program interacts with the hardware. Thanks for asking.
@@WhiteboardDoodles24 assembly language gives me direct access to the hardware.but high level language also give access to the hardware but indirectly.so high level language do everything that assembly language do but indirectly.so there is no difference.
@@tamimayan2028 Great point. You're right that high-level languages can indirectly access hardware, but Assembly can do some things more precisely because it directly communicates with the CPU. For example, imagine you're programming a blinking LED on a simple microcontroller. In Assembly, you can control exactly when and how the CPU sends the signal to turn the LED on and off - down to the exact cycle. High-level languages rely on pre-written libraries for this, which might not give you the same precision or flexibility. So, while high-level languages can achieve similar results, Assembly allows you to customize and optimize the process in ways that aren't always possible with higher-level abstractions. Thanks for bringing this up.
I wanted to provide a quick overview of basic Assembly instructions, but you're right - going in-depth with each command deserves more attention. I'll make sure to cover these in a future video, with a slower pace and more detailed explanations. Thanks for your feedback.
Learning languages like C and Assembly is surely a very rewarding skill, although a bit more challenging. I still haven't exactly decided on all the videos I want to cover now but expanding the programming playlist and creating dedicated videos for different programming languages (like C, Java, Python, etc) is definitely one of the goals. You can expect such videos about C and other programming topics in the first quarter of this year so stay tuned. Thank you for your suggestions and engagement.
Assembly is certainly a foundational skill for understanding how software works at a low level, including reverse engineering for legitimate purposes like debugging or security research. Technically speaking, yes, however, those skills should always be applied ethically and legally.
Great question. Learning Assembly can be a bit challenging at first because it's closer to how the computer actually works, but with time and practice, it becomes easier to understand. If you're interested in how hardware interacts with software, it can be really rewarding. Starting with simple programs and gradually building up is a good approach.
That's a good observation. At its core, everything boils down to the binary on/off signals that hardware understands. Assembly serves as a bridge between these binary instructions and higher-level languages, making it easier for us to code. Thanks for your input.
Thanks for the kind words. The visuals are actually SVGs and not hand-drawn, but I'm glad they help make the concepts clearer. Appreciate your support.

Basically pretend you have this weird electronic object that has various buttons on it. The object is capable of holding isolated "bits" of info (on or off) in containers (called registers). It can also shift those bits around. Think like a row of light switches as a register but the light switches are a lot smaller. If you have 10 switches and the first 9 are in the off position and the 10th is in the on position. Well then pretend (just for the hell of it) you actually want the first switch on and the remaining 9 off. Well you aren't going to physically move the light switch from the wall and place it at the beginning. Instead you are just going to flip the first one on and flip the last off. So that's one thing this weird object does but how? Well it has the buttons right? Well turns out if you press some (or all) of those buttons in specific order and at the right time, you can flip those light switches how you want to. However, you find out that that to do that one example from a ove you have to press A LOT of those buttons and you have to do it at weird time intervals. And turns out to get anything useful out of these switch flips (for humans) you have do a A LOT (and I mean A LOT) of these "switch flips" operations. It's too hard to do mechanically (or basically impossible). So what do you do? You build a table where one column are "mnemonics" (short human reable words), and the other column is a serious of button pushes. Then you build another weird electronic object that can parse/read those mnemonics that you wrote on a txt file, look at the table and push those buttons for you in the correct order and at the right times.
If you have no previous experience with any kind of programming, assembly can be a tough place to start. This is just a overview / introduction, so don't be shocked if you feel a little lost, it will eventually pass as you learn more about it. Or if you find assembly too hard, maybe try a high level language like Python, it's super simple for beginners and much more forgiving than starting with something like C (too low level) or Scheme (too abstract). Don't get me wrong, it's perfectly possible to start with Assembly, C, Scheme or almost any other language, but it all depends on how good is the material you're using to learn from, and most material I've found for C and Scheme will only work for a highly motivated individual who is comfortable seeking additional information by himself or herself. Something like Python or Ruby is much easier to start with, then after you got the basics and are comfortable with it, you can migrate to another language if you feel like it isn't a good fit for what you want to do.
If you are asking whether I use AI to respond to comments, the answer is no. I personally write each response to make sure it shows my perspective and engages with viewers authentically. Let me know if you meant something else.
You're right - what makes a programming language easier or harder really depends on personal preference and experience. For some, like you, understanding how high-level commands translate to CPU instructions makes lower-level languages like Assembly more intuitive. Others might prefer the simplicity of high-level languages like Java or Python. It all depends on how you like to approach programming.
@@WhiteboardDoodles24I took a look into the linux source code multiple times to search for the instruction to use a primary monitor and a secondary monitor with one graphic card that provide to connect two monitors. I know how to get the EDID data from the primary monitor, but i don’t how to get the data from the secondary monitor. I know how to use the functions of the VBE 3 bios to switch into a refreshrate controlled graphic mode using the primary linear framebuffer(address from mode specific info) and in the Windows device manager we can see the linear address of the secondary framebuffer, but i don’t know how to change the videomode for the secondary monitor. Some graphic cards start in clone mode, so the second monitor display the content of the primary framebuffer too, or it display a message with no signal. If it is possible i want to use different video modes&refreshrates and that the secondary monitor display the content of the secondary linear framebuffer.

The need for using Assembly has decreased considerably as compilers for langues like C have become so optimized that they produce faster and more efficient code than human programmers using Assembly directly.
Modern compilers for languages like C have indeed become highly optimized, often producing code that rivals or even surpasses what could be written manually in Assembly for many applications. However, Assembly is still valuable in certain situations, such as when low-level control over hardware is needed or in performance-critical sections of code where even the smallest optimizations matter. It's also helpful for understanding how high-level code translates into machine instructions. Thanks for sharing your insights.
I use assembly just for fun and i know some tips like memory and code alignment or paralell execution with pairing simple and complex instructions to prevent stall.

You're right - what makes a programming language easier or harder really depends on personal preference and experience. For some, like you, understanding how high-level commands translate to CPU instructions makes lower-level languages like Assembly more intuitive. Others might prefer the simplicity of high-level languages like Java or Python. It all depends on how you like to approach programming.
@@WhiteboardDoodles24Yes, thx.
@@WhiteboardDoodles24I took a look into the linux source code multiple times to search for the instruction to use a primary monitor and a secondary monitor with one graphic card that provide to connect two monitors.
I know how to get the EDID data from the primary monitor, but i don’t how to get the data from the secondary monitor.
I know how to use the functions of the VBE 3 bios to switch into a refreshrate controlled graphic mode using the primary linear framebuffer(address from mode specific info) and in the Windows device manager we can see the linear address of the secondary framebuffer, but i don’t know how to change the videomode for the secondary monitor. Some graphic cards start in clone mode, so the second monitor display the content of the primary framebuffer too, or it display a message with no signal.
If it is possible i want to use different video modes&refreshrates and that the secondary monitor display the content of the secondary linear framebuffer. I like to use the 16 bit "BIG" Real Mode with 4 gb segment size for DS,ES,FS,GS segment + A20 address line on on 80386+ CPU.
The video should be checked for high pitch sound.
I reviewed the audio on different devices and didn't notice any high-pitched sound. It might be a local issue on your end. Could you please tell me where exactly in the video you experienced the high-pitched sound?

I too am feeling it, every now and then when the speech is being used I hear "squeaks" if it makes sense. I thought it was just a issue @ my side, but now someone has mentioned it maybe it's something
The need for using Assembly has decreased considerably as compilers for langues like C have become so optimized that they produce faster and more efficient code than human programmers using Assembly directly.
Modern compilers for languages like C have indeed become highly optimized, often producing code that rivals or even surpasses what could be written manually in Assembly for many applications. However, Assembly is still valuable in certain situations, such as when low-level control over hardware is needed or in performance-critical sections of code where even the smallest optimizations matter. It's also helpful for understanding how high-level code translates into machine instructions. Thanks for sharing your insights.
I use assembly just for fun and i know some tips like memory and code alignment or paralell execution with pairing simple and complex instructions to prevent stall.

THAT IS NOT A REAL HAND YOU ARE NOT DRAWING IT THAT FAST AND CHANGING COLORS INSTANTLY. ITS FAKE
You are right. It is not a real hand. I use animation software to create visuals, which allows for quick drawing and instant color changes. It's all about making the content engaging and easy to follow.
@@WhiteboardDoodles24 ok.
