@@dr_davinci my question is not that i am asking how cpu or alu know that this is a negative number and then make sign bit as 1 i understand if sign bit is 1 then the number is negative but how cpu or alu will know that this number is negative

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 that has to be send to the memory................ooops quite correction there.. by the way your lecture delevering technique is so good
@@surajdev1186 just like your calls are sent through telephone lines, but the sender is your cellphone/telephone, in the same way, the part of cpu which stores and send the address to memory is the address register AR. The address itself is sent by electric signals through the address bus but the sender is the AR.
In memory write operation CPU will first send Enable write signal to the Memory or firstly it will send data then it will send enable write signal...?? Please Ans sir
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.
so from ar register, it takes the address that is in CPU and then goes to the memory or their memory is having its own ar register? (might be a foolish question)

how alu check that result is positive or negative??
@@KabbadiStar you do a - b , if you get the sign bit as 1 then a < b otherwise maybe equal of greater !!

thanks mam
I was here for my semester exams and these lectures are very very good
Very nice lecture from a very nice teacher 😁
Start Time: 10:10
Although I joined made easy but regularly I watch unacademy videos
Because memory does not have any operational unit , it is just a storage device and to make it understood what to do RD is send from processor.
excellent explanation sir. Thank You
मज़ा आ गया वाह 😎😎😍
People should like the video of they
Are getting benifits from free education
sir maza a gya , you are wonderful
Cpu sends read signal to memory becouse firstly memory will also have to understand the content which is in memory.then it can send data to memory.
first time in my life i got addicted to a study related playlist
Thank you sir for free lectures
Love you Sir
Love for your lecture
Sir 🧑💻🧑💻🧑💻🧑💻👌👌👌👌🙏🙏🙏🙏
Excellent 👍
Completed.thanku sir to providing such a good quality education free
Beautiful explanation 😊
Read signal sended by cpu to enable read mode and after that data of read is sended to the memory to the cpu using address bus.
Awssm lectures
Please provide more and more lectures
Sir you are awesome 🥰
Sir you are best
Thank you very much sir and whole unacademy team for providing such great subject contents.
Bro where are ppts uploaded? Link in description not working

i love your lectures

Stack is just a data structure which we implement to organize data, it not something physical , how come there is stack pointer?
Is micro-operation present in EC syllabus
From where I can get the notes ?

address is sent to memory via address bus but the one sending that address is the address register

great
so from ar register, it takes the address that is in CPU and then goes to the memory or their memory is having its own ar register? (might be a foolish question)
Address that's in CPU
Think of accessing data of an element with pointer
the address points the location of the memory cells that needs to be accessed, it does not store the address in memory.
Sir read signal is going from cpu to memory for checking that memory is free or not
best video
sir I wont do these micro operations, i will say either find fridge or sit quietly
memory to cpu and write cpu to memory
Sir address and data register about which memory you have taking ( primary memory or secondary memory)
Primay memory
27:20 nice one XD
Can someone tell me from where I can get these lecture notes🙏🙏

Thanks sir
Have you got iit

Hi-day-1
👍👍
Becouse cpu have control unit
He not solve gate examples questions
Already separate PYQ sessions have been taken.
You can go through it before putting any offhand comment.
Thank you sir
