How does a Computer understand your Program?

  • Опубликовано: 15 авг 2024
  • Ever wondered how the code you've written in any programming language is understood by your computer, and computed mostly within milli-seconds?
    Use spyse to gather information while pen-testing : spyse.com
    Stay buckled up, there is going to be a new update for spyse soon, which include lots of additional cool features!
    Does your computer understand english alphabets and numbers so that it can deal with your program?
    How exactly is your computer able to execute the program written by you?
    Well, it's nothing less than a "magic". The program you write in any language is actually converted to machine instructions (binary information) so that your computer understands it!
    Your computer can only understand two states, either 0 or 1!
    The compilation system is what converts the source code into the machine instructions, which your computer executes.
    Imagine how this compilation system is designed and developed? They are also written using programming languages! But how? Well, at some point back in the past, the tools inside compilation system are written purely in machine code! YES, using just 0's and 1's!
    How genius people are, back in those days!
    We honestly need to thank those people who made these compilers, using which we were able to run our programs. NO COMPILERS means one should write code directly in machine language, and imagine how complex that would be!

      Idk if he made it or not later. But usually the code gets stored in memory (ram) with it’s allocated space.
      And it’s my understanding that, the kernal instructs the machine to initiate the memory locations.

    I was following along until about halfway when we were talking about the .i or the .o and all that. So when you said "obviously" after throwing up all those graphics of a whole computer I thought, "Oh yeah, this is the most obvious thing to any person ever."
    I suppose i'm off to search how a transistor works. Cuz i know that language is converted into binary through a series of steps, and has stuff added to it to create and executable that has more binary for the machine to run. But I suppose i don't understand well enough how a binary code is sent to a transistor/lots of transistors

    A great job. I am wondering if you can take it a step deeper. For example, can you show how, specifically, a computer can evaluate an if statement? How does it know Apple becomes before Bananna or 10 is geater than 5. Even more so, when one has a very complex logic request, nested ifs. Every video I listen to, takes me through the stages, but I never understand or see how he darn thing comes up with the answer. I know there are layers on layers, but i is amazing how computers are able to be so intelligent with just zeros and ones. Thanks.

    My question, is how does the computer know to even read the data... What a 1 or 0 even means, and that it has a meaning. How the hell do transistors turn into knowledge in the first place?! I've never seen anyone explain that part.

    • @amaze2n
      @amaze2n Год назад +1

      It's electronics. A 1 represents a voltage above a certain threshold, a 0 represents a voltage below a certain threshold. Every computation can be broken down into basic logical operations (AND, OR, NOT). So at the lowest level, everything starts with electronic circuits that implement these operations. For example, an AND gate is designed to output a voltage above a threshold only if both inputs are above the threshold. By chaining these gates together you can implement arbitrarily complex logic (from simple addition to anything you can think of). Conceptually, it's similar to the fact any sound wave, no matter how strange it looks, is just a superposition of simple sine waves.
      Knowledge is just an abstraction represented by these electrical impulses. Computer scientists designed a coherent system for representing and operating on data depending on its type. Type just determines the way we interpret a certain set of 1s and 0s in memory. A lot of it is convention. Floats and strings can be represented in different ways, we just decide on a specific convention to use. By putting all of these building blocks together, we can print out words to a screen, do math and print the correct answer in Arabic numerals on the screen, etc.
