Why we make 4-bit group in hexadecimal number system and make 3-bit group in octal number system???????? Plz give answers 🧐🧐🧐🧐🧐🧐🧐🧐

[@josephchal8709]

​@@feel__motive because the binary 0 and 1 will be arranged in 2 to the power manner ,for example can you represent 13 in 3bit manner if do it can't because 3bit have highest value is about to 7 so we make it 4bit for hexadecimal and 3bit for octal

[@poojashah6183]

Thanks for this(to the point)information 🙏🏻👍🏻

[@tarjbaxi2400]

Very well explained sir! Doing a great job by uploading these videos. :):)

[@ignatii_ars]

Great video!

[@vinuramendis2273]

You are the best❤️

[@mayurshah9131]

JUST SUPERB 👍👍

[@barlolabalaraju1497]

Very useful tq soo much

[@ArjunFacts_]

Very good explanation sir

[@UE_devlover]

Very awesome explanation sir 👍🏻

[@mohanaddalol]

i couldn't thank you enough

[@justpaulo]

In the - Decimal to Octal Conversion - Decimal to Hexadecimal Conversion I also recommend to convert it to binary 1st, and then covert it to Oct or Hex. The reason being that it is much easier to divide and multiply by 2 and going from Bin to Oct or Hex it's trivial.

[@Ineoa20k]

Kind of teacher i need to understand

[@Harshavardhan-zr2ip]

Sir pls make a video on CMOS technology

[@justcurious1940]

can u convert hexa to octa or octa to hexa without going through binary ?

[@pranavsharma4308]

good

[@aaryamhatre7351]

Sir I got full marks in computer by listening your lesson

[@ALLABOUTELECTRONICS]

Great.. keep it up 👍🏻

[@sumit3416]

wht test? how many videos?

[@vinuramendis2273]

❤️

[@challengemania4447]

the binary representation of hexadecimal number C3 is ??

[@shameditz7520]

Hi sir.... Any easy method to calculate fraction negative value like (7*8^-2) and (1*8^-1)?

[@theflamecoreguy7929]

Plz plz plz make a video about amplifier low and high freq response I can't understand it and I have exams on 6th aug 😣

[@puneethvm]

👌

[@tambwepungwe]

Hi please tell me, why do we use a set of 3 symbols ex: 011, 111,101 while converting from binary to octal and use a set of 4 symbols while converting from binary to hexadecimal ex: 0111, 1010, 1101 etc. Thanks

[@ALLABOUTELECTRONICS]

Because in the octal system we have total 8 different digits and in binary, they can be represented using 3 bits. That’s why during binary to octal conversion, the groups of three digits are made. The same is true for the Hexadecimal number. In hexadecimal system, we have total 16 different digits and to represent them in binary we require 4 bits.

[@dhruvsinghsolanki7845]

How will we convert decimal to hexadecimal with upto 4 decimal places like 1234.5678 and why are we only multiplying 16 0r 8 4 times like at 21:06. Will we always do it just 4 time or is there some rule.

[@ALLABOUTELECTRONICS]

No, there is no hard & fast rule to do conversion only upto 4 places only. If you required you can go further also.

[@feel__motive]

Sir why we make 4- bit group in hexadecimal number system and make 3- bit group in octal number system??? Plz reply me with satisfactory answer

[@ALLABOUTELECTRONICS]

Hexadecimal number system consists of 16 symbols. Using the 4 bits ( 2^4) all 16 symbols can be represented. Therefore, during binary to hex conversion, we are making the group of 4 bits. Same way, in octal number system, there are 8 symbols and they can be represented using 3 bits. I hope, it will clear your doubt.

[@feel__motive]

@@ALLABOUTELECTRONICS sir apki baat theek hai laikin group bnana lazmi hai kya in both conversation...... ..... But thanks for your help 😘😘😘. Plz help some more........

[@avidrationalist7281]

where are 8 symbols at time lap 2:21????????????????????????????? where is 5 ????

[@ALLABOUTELECTRONICS]

0 to 7 are the 8 symbols in octal number system. In binary we have only two ( 0 and 1). In decimal we have 10 ( 0 to 9). Similarly in octal number system we have 8 symbols ( 0 to 7).

Not able to understand anything

[@mathit9014]

Sir would you mind please providing the notes in pdf or ppt formats....It would be extremely helpful to revise the topics.
