    23:00 Never ever actually thought how the conditions were checked inside the ALU , It was so interesting to know how (a>b) uses (a-b) and checks if the result is -ve or +ve to get the result.... mind blown, you took such a great example to clear this concept, hats off to you sir.

    How will memory know, when do CPU wants to read and from where?
    firstly CPU decodes the instruction from its instruction register to know whether it has to read or not and from which location, then according to that, control signals for read operation are given to the memory along with the address. So that it can fetch the content of that particular address using data bus.

    CPU is the one which controls all the other units. So it only makes sense if CPU sends the read/write signal to the memory telling it which function to perform . if the memory sends the read write signal to the CPU, the cpu will have no function to perform with it.

    sir apne addres register ko define karte time likha h "it is used to send address to memory"....
    jabki ye kaam address bus karte h , adress register is just like memory that is used to store the adress

    CPU send read signal to memory because, when signal is received by memory then memory realize cpu is ready to do operation on data, that's why memory start reading data and send data to cpu by data bus.
