BITS & COMBINATIONS

A bit
A bit is a "yes" or a "no": yes or no electricity (RAM memory), yes or no light (DVD), yes or no positive magnetic force (Hard disk), and in text "no" = 0, and "yes" = 1

A group of 8 bits is called a byte. I personally would like to drop that name because it is confusing: Kb = kilo bit, and KB = kilo byte (eight times more than a Kb). Any number of bits can make a combination, a group of 8 is common but nothing more than that. Let's also drop the kilo being 1024, because we agreed 1 kilo = 1000. At this moment, one Kilo Byte = 8 * 1024 = 8192 bits.

This is how to read 8 bits:
the first bit on the right can be 0 or 1
bit #2 can be 0 or 2
bit #3 can be 0 or 4
bit #4 can be 0 or 8
bit #5 can be 0 or 16
bit #6 can be 0 or 32
bit #7 can be 0 or 64
bit #8 can be 0 or 128
All "yes" bits together are 255, but there's also zero when all bits are "no", so the total number of combinations is 256.
11111111 = 128 + 64 + 32 + 16 + 8 + 4 + 2 + 1 = 255
00000000 = 0 + 0 + 0 + 0 + 0 + 0 + 0 + 0 = 0



By combining the bits, any whole number from 000 to 255 can be created, for example:
01001011 = 0 + 64 + 0 + 0 + 8 + 0 + 2 + 1 = 75
10110100 = 128 + 0 + 32 + 16 + 0 + 4 + 0 + 0 = 180

COMBINATIONS

One bit can be one out of two combinations:
0
1

Two bits can together be one out of four combinations:
00
01
10
11

Three bits can together be one out of eight combinations:
000
001
010
011
100
101
110
111

The amount of combinations that can be made with a certain amount of bits is:
2 ^ the amount of bits.
2^1 = 2
2^2 = 2x2 = 4
2^3 = 2x2x2 = 8
2^4 = 2x2x2x2 = 16
And so on. Note that every bit extra, simply doubles the amount of combinations:
2^5 = 32
2^6 = 64
2^7 = 128
2^8 = 256
2^9 = 512
2^10 = 1024
2^11 = 2048
2^12 = 4096
And so on.
On a calculator, search for: Yx


256 RGB pixels (a tiny 16x16 image) are together:
16x16x24 = 6144 bits,
thus the amount of combinations is:
2^6144 =
