    What I understand is 32 bit windows 7 and 64 bit for windows 8 above 😂

    "That number is so huge, we will never need to access that amount of memory"

    People from the year 3021 with a smartphone.
    "How did people survive in 2021 only being able to access 64 exabytes of memory"

    So with 4 gb of RAM it doesnt matter if its 32 or 64?

  4. …And based on how we perceive the CPU architecture, the main "registers" would be 64 bit registers, contrary to the 32-bit architecture. As a result, the logical and computational departments in the CPU have better handling of the most primitive calculations in comparison to the 32 bit. In fact, they have the capabilities to do any calculations on twice data in the same clock ticks roughly speaking and it yields better overall performance.

    "never need to use that amount of memory" yaaaa thats what they said back in the 20th century with computer beginnings that caused the big Y2K scare. hahahhaaa hmmmm


    1-6GB=32bit OS – if there are drivers for 32 bit OS
    8-..GB=64bit OS

    "64bit" is not just an ability to use more memory! Your missing out on informing folks of the CPU architectural changes, itself. "64bit" is PRIMARILY talking about the CPU and it's ability to not just address more memory, but (crucially), it's ability to OPERATE on 64bits of data – at one time. This is important since discussions about 8bit, 16bit, 32bit and 64bit CPU's is very misleading if you talk about the address buss – which frequently set at a maximum value not what you would expect. Instead, it's all about the data size the CPU's 'general' instructions can operate on ('specialised' instructions can operate on other sizes)

    …its x86 or x64….
    when you say x32, you usually mean x86.

    thank you! how does 2^32 = 4.3 billion become byte instead of bits ?

    Great explanation! I now understand the difference. Thanks.

    Fantastic way to learn something i never have pay attention Thanks

    Can you also make videos on how computer works? Like Transistors, binaries and those?

  13. I'm just glad the comments are roasting you that ignorant ass comment about never needing that much memory. Never say never.

    A simulation of the Earth would need far more than 16 billion GB (16 EB) of RAM, if only because it would need to emulate a billion devices that each have 16GB of RAM.
