Did someone say... Celsius?
0 - freezing
10 - cold
20 - cool
30 - warm
40 - hot
There you go. Freezing, Cold, Cool, Warm, Hot, starting at 0. Celsius is sooooo much easier then Fahrenheit.
AS FOR BINARY, Another lowdown!
Binary is base 2. We normally use base 10.
00, 01, 02, 03, 04, 05, 06, 07, 08, 09
10, 11, 12, 13, 14, 15, 16, 17, 18, 19
That's base 10. Base two is...
00, 01
10, 11
There you go. Now, binary is stored in Bytes. Each Bytes has 8 bits. In laymens terms, the computer stored stuff in chunks of 8 digits.
00000000
So, how can you easily see what is being shown?
01001011
It's not easy to look at a huge stream of 1's and 0's and figure stuff out. So, it's split into two four-digit groups, called Nybbles. Nybbles, Bytes, get it? haha?
Anyway, split into two different groups of 4 digits.
0000
0000
Each group of four digits can count up to a max of 16.
0000 - 0
0001 - 1
0010 - 2
0011 - 3
0100 - 4
0101 - 5
0110 - 6
0111 - 7
1000 - 8
1001 - 9
1010 - 10
1011 - 11
1100 - 12
1101 - 13
1110 - 14
1111 - 15
Since we started at 0, thats 16 different possible numbers. Well, heck, lets just count in base 16! Base 16 is:
00, 01, 02, 03, 04, 05, 06, 07, 08, 09, 0A, 0B, 0C, 0D, 0E, 0F
10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 1A, 1B, 1C, 1D, 1E, 1F
As you can see, the extra numbers are replaced with letters. Now we can represent bytes with two hex digits, like so.
FF = 1111, 1111
F0 = 1111, 0000
etc, etc.
NOW YOU KNOW!
(The same applies for base 8, but that's for 3 bits, 000)
