What is the easiest way to learn the binary system?

Answer 1

By Kathleen Fung / I just forgot to sign in b4 i did this

Ok because I love Binary Code I think I can explain how it works so here you go....

Binary Code

When reading binary code you HAVE to read it from Right to left not normally from left to right. There are slots you use. 8 actually. So how it works is slot are worth diffrent amount of #'s

1= 1

2= 2

3= 4

4= 8

5= 16

6= 32

7= 64

8= 128

So there all the numbers ahead of them times themselves....so its nxn in an algebra expression.

Question: (answer them)

a) 100

b) 0001000

c)100000

d)0010

Answers:

a)4

b)4

c)32

d)2

To get the total value of a binary # add the values corresponding to each slot. so for example three in binary would be 00000011 or just 11

The above corresponds to three because if you add the total values of all the slots, that is to say a one from the slot to the right, and a two from the second slot to the right, then it equals three.

(e.g) let's say you wanted to represent 5 in binary terms. Then you would nees a value of one to be a value of two:

101 (101= 1(equals four)+0(equals two)+1(equals one)= 5 so its 4+1=5

additional (e.g)

001011 (1+1+0+1+0+0/ thirty two+sixteen+eight+four+two+one=11

ASCII is essentially the letters, numbers, and symbols that are stored in our computers throught the use of fonts. When the keyboard repays the buttond you pressed, it sends in a code which is then converted to the ASCII equivalent of 'k' or '5' or whatever key you press.

(e.g) 0100100001100101011011000110110001101111

there are only so many letters, #, and symbols stored for ASCII. having setd of 8 didgets for their binary equivalent is more than enough to represent all of these letters and the like. As such, all strigns that represent text like the one above are separated into bits of 8 for simplicity.

01001000 01100101 01101100 01101100 01101111

So our example message was separated into 8 didget strigns the decimal value for each of these strigns in the example I calculate for you.

01001000 = 72

01100101 = 101

01101100 = 108

01101100 = 108

01101111 = 111

Now there is something called ASCII Table. It coresponds to the binary # from 1/ or to the equivalent #'s/Letters/ Symbols. But since we found the decimal values of these strings we can use a major short cut.

By pressing ALT and (#) on the phone looking/number pad you will get the ASCII equivalent for that #. for e.g my message was.....

72 = H

101 = E

108 = L

108 = L

111 = O

Question:

0100001101101111011011100110011101110010011000010111010001

1101010110110001100001011101000110100101101101111011011100

111001100100001

(its all together)

so do what i just showed you with the 'HELLO' one. separate them into slots/strigns of 8.

i did this one when i was learning this as well so this is all from my sheet of work i did....

67 = C

111 = o

110 = n

103 = g

114 = r

97 = a

116 = t

117 = u

108 = l

97 = a

116 = t

105 = i

111 = o

110 = n

115 = s

33 = !

Because in our # slots we only go up to eight this is the # slots for you...

______ _____ _____ ______ _____ _____ _______ _______

128 64 32 16 8 4 2 1

REMEMBER READ FROM RIGHT TO LEFT

and because It took so long for me to test all the letters #'s and symbols i could get these are the ones i got....

and the symbols if you want them ou have to try and find yourself though there throught #'s 1 and 38 and some more that i didn't get to.

so another E.G before i go is

1101001010000110001011100001011000110110101001101010011001110110

which is my name Kathleen.

So good luck with this Code and remember a 13 year old can learn this to because that's me :)
