    Sir this is really useful and helpful and all and I appreciate the explanation, but I have a small question. How come in this part of the video (8:21), why is 12/2=6 how is there a remainder of 1, but when you did 6/2=3 and there is no remainder? Same with 3/2=1 but there isn't a remainder I am confused.

    • @stings7
      @stings7 Місяць тому

      if we divide with 2 and it is a perfect division for example 2 divided by 12 equals 6 which does not have any remainder therefore it will not have 1 remainder the remainder you are talking about is from the upper box where we divided 2 by 25 which is an imperfect division thus having a remainder

    at 9:08 when converting 67 into binary numbers, isn't the answers supposed to be 1000011 instead, I am confused p.s nvm I know why did u put an extra zero in the front now

    • @mrbulmerslearningzone
      @mrbulmerslearningzone  4 місяці тому

      ok... it is an 8 bit register, therefore the numbers refer to 128, 64, 32, 16, 8, 4, 2, 1... there are no 128s, 1x64 and 1x2 and 1x1 . So yes, you are correct with 1000011, but the extra zero at the front does signify an 8 bit register.

      Most of the syllabuses follow a similar pattern…especially with Data Representation…

  • @xml_rblx9576
    @xml_rblx9576 4 місяці тому

    so the byte is a bunch of information stored as numbers and it is actually numbers too so for example we have the number 28365016 so how will the computer know what this information of numbers is?

    • @mrbulmerslearningzone
      @mrbulmerslearningzone  4 місяці тому

      The number 28,365,016 can be represented in various number systems:
      • Decimal (Base 10): The form humans typically use, which is 28,365,016.
      • Binary (Base 2): The form computers use, which for 28,365,016 is 1101011111111010110111000.
