why am I paying tuition?
Bcz you are dumb
😂
Legit trying to pass the course using chatGPT to explain stuff
Maybe for practical 🗿
Who is Neso Academy?
To the blind, he is the light.💡
To the starving, he is the bread. 🍞
To the sick, he is the cure. 💊
To the lonely, he is companion. 🙌🏼
To the sad, he is joy. 😁
To the prisoner, he is freedom. 🏃🏽⛓
To the poor, he is treasure. 🎁
For me, he is EVERYTHING.
On the real...This topic is gonna be in my computer science exam tommorow, and I don't really understand it, but here comes Neso Academy, saving uni students lol. Glad and grateful for your channel
8:52 "Why there is a 10 bits fixed memory space?
is it for the decimal number system?
Or just for the 4 bit situation?
*What happens if there is a 32 bit situation??"
It would be a great help to clear my doubt..
bro, u r so lucky if this is what's in your exams
0:13 intro is very annoying
The entire video is
The entire video is
I pay tuition fee in campus but here is where I really get to learn .
same here 🤣🤣🤣🤣

Absolutely
Here too, you are paying to wifi provider, this youtube channel and precious time
Yt channel dead?
I still can't understand this shit
Woaah!! 2.12M subs. You deserve it bro. Your channel popped out of nowhere in my feed. You're the one who made me pass so many of my subjects in college and you had very less subs at that time and I used to comment you'll be big and here you are. I'm also doing really fine now, having studied from your videos during college.
5:30 then what rhs means in definatiion you moved the radix to the left side
same here...i think it should be lhs
Your teaching way is so adorable I wish to god your growth increase so soon 🎉
8:47 , why is it stored in 10 bit fixed memory?
very nice explanation thank you so much.. .but i have a doubt...about implicit representation...why we shift decimal towards left in that??
Here bias is 8 for 4 bit exponent i.e. (2^(n-1)).
But in IEEE standard why bias is 127 for 8 bit exponent, why not 128?

10 bit given is just for example. For 32bit, 1 bit is for sign, 8 bits for exponent, and 23 bits for mantissa
in Biasing for 4 bit is 7(2^(n-1) -1), at 7:52 add 8 to all numbers in a range instead of 7!
10:52 how did you know it's a positive number can I know please?
im wondering the same :o
because it was 5 (positive number) and he converted it in four bit notation it is (0101) with 0 indicating postivity
God send you to help us through out our university exams and better understanding of concepts.... Just got a crystal clear concept after watching a video just 1 time .... Thanks a lot man 🙏🏻❤
same hereeee
at 10:55 i have a confusion i think if msb is 1 then sign should be 1 because number is negative if not then please explain me how to find sign ?? and how it is 0 in the mentioned timeline
How do we decide where to use implicit and explicit normalisation, like you used explicit for 0.0101 but implicit for 101.101?
Didn't get the explanation of implicit normalization
Thank you so much for the great tutorials.

12:53 so 101.101 is 3.3? bcoz it cant be 101.101 bcoz we only can use 0 and 1 bcoz wecant magically bring back 201.101 in implicit methos LOL
but we can do it 201.101x 10exp bcoz we use decimal now LOL
or bcoz you do programming not matter if this bytes are 201 and these bytes are .101 its not matter how you do it you program it doing it
give your chunk of memory to someone else. its like crypted message if not tell its floating point using binary 4bit exponent 5 bit data.
still why its not universal this is it.. well later it is when computers can store more and faster we have 1million bits for exponent and 1million bits for value LOL and dats that its universal
8:08 its allready signes why need convert it back to int when its allready int on memory. we just read it as signed LOL. go on allready tell this magic floating number OR was that allready
sign bit exponent bits can be how much you want(you need) then mantissa also how many you want. how this is universal so others can read it not just you that make program to read it LOL
Allen Gary Martin Cynthia Brown Larry
5:37 not matter we allready told 2 exp 3. just not understand what 2 is we have 3 thats mount we move point lol and i not see any diff is 2 is 10 exp is that move point lol. its same as 2+2=4 when 1+3=4 result is same LOL
9:10 got it got it, but we can use 2 bits also bcoz its -1 who this is universal way when its not fixed. you need know what is stored before can use lol.
that could be "hello world!" string in memory and that could be floating number if we tell to read it and way we want this time we use 4 bit exponent. why is not fixed?
6:50 now you take of what you allready said LOL and yes signed int is -+ half of bits you have lol and biggest + is 1 less
Where is compiler design lectures please finish those...
Thank you..

awesome tutorial for computer engineers thanks for making sir
1:48 yes simple as that 5625 in memory and exponent 1 or just write 5 and 625 . is middle lol
you are amazing . it was very helpull thank you a lot
8:22 not matter if you try make case one is better than other they are not now (101.101) both lol
could you explain more on why 2's complement is not used due to the ordering
Haaaaaaloo everyone😂😅😅😂😂
east or west , NESO academy is the best❤🔥❤🔥❤🔥❤🔥
Hi! Thanks for this video, but could I simply ask why did you add 8 (+8) to the equivalent values of 2's complement?
He added that bias to make the negative Power to positive...abd which is again balanced in the human readable formula 2^(E-bias)
In fact, the formula is E=exponent+BIAS, as the BIAS is the excess, in this case it is 8. -1 is the exponent of 2. So E=-1+8=7.
Ok, explaied to understand where is it? What it is 🎉 thank god you are here
9:40 yes that signed -1 in 4 bit why we need calculate 7
One of the best free resources on the internet which are high quality.

I think there is a mistake because you are adding 8 as bias for 4-bits, whereas the bias for 4 bits should be 7.
Is this correct?
ENSIA students ✨⭐🌃
Ur dad
In implicit normalization .... We need to move to the Right side, right?
But sir, u moved to the left...
No, we move to the right of the most significant bit, which means moving to the left
Sorry for the comment spamming.I will delete the duplicates as soon as I get the answers.
annoying as hell
Duplicates mean?
thanksssssss
thanks
wonderful video, thank you.
i loved it, thank you for your service sir!

How implicit sign is 0 +ve i did not understand
this question comes for 2 marks and one has to solve it in 1min. It's not possible 🥲🥲
this is so much easier to follow than my lecture - thank you !
thanks sir explanation top notch
Thnku very much sir for the help
great video
YOU ARE MY HERO
observe
I LOVE you man.
Good explanation

One is the smallest number after zero...i cant have 0.5 of one...two cannot have fractions...but can be split in half...i cant subtract more than i have...i cant do it at all...if i have 5 i cant take away 10...i can only subtract 5...same for division..i can only divide if its less than the number...3/2...not 2/3...minus numbers dont exist...i can't have a minus a billion Lamborghinis...i cant have zero of everything...i just dont have 1 of something...
Me watching in 10x 😂
