Lol
Do you get the binary concept?
128-64-32-16-8-4-2-1
-------------------------------
0 0 0 0 0 0 0 0 | = 0
0 0 0 0 0 0 0 1 | = 1
0 0 0 0 0 0 1 0 | = 2
0 0 0 0 0 0 1 1 | = 3
Isn't it
I like this -
heh
Decimal is a Base10 counting system. That is, we count 0,1,2,3,4,5,6,7,8,9 then +1 to the next column and start again
10,11,12,13,14,15,16,17,18,19.
Binary is Base2, meaning we have 0 and 1.
In computing, things are usually set in Bytes, which is 8 bits which is 00000000.
same as in decimal, we count upwards from the right adding to the left.
Counting to Decimal 10 using 4 bits ( a nibble) looks like this:
0000
0001
0010
0011
0100
0101
0110
0111
1000
1001
1010
Decimal counting goes like this: HTU (Hundred, Ten, Unit) which all know well, and each above unit is a multiple of 10.
Binary counting goes like this: ABCDEFGH
A is 128 - B is 64 - C is 32 - D is 16 - E is 8 - F is 4 - G is 2 and H is 1
each one is a power of 2 (2*2 x times, so 2 to the power of 4 is (((2*2)*2)*2) which is 16)
9 is the highest you can do in decimal, 1 is the highest in binary.
I'm half asleep so I hope this makes sense lol -

It is easy. 256 128 64 32 16 8 4 2 1
ok when you want to turn a number into a binary number, all you have to do is use simple division. lets say you want to turn 18 into a binary number..
all you would have to do if figure out the smallest number that would go into it. 256 128 64 32 do not go into it. so all of those numbers would be 0. 16 goes into it 1 so you put a 1 there. but you still have 3. 8 and 4 doesn't go into 3 so those would be 0 also but 2 and 1 go into it so they would be 1 so it would look like this.
256=0
128=0
64=0
32=0
16=1
8=0
4=0
2=1
1=1
000010011=18 -

For ASCII capital chars:
01000001 would be A
01000010 would be B
01000011 would be C
so on............ -

wait, im not wanting to know binary letters lol
