Binary strings use only the digits 0 or 1.
In computing, binary strings can represent many things.
Here we will restrict the use to whole numbers: 0, 1, 2, 3, ...
For an 8-bit binary number, the column weightings are:
128
64
32
16
8
4
2
1
Digits are grouped in fours from the right for easier reading.
The smallest binary number 0000 0000
represents 0x128 + 0x64 + 0x32 + 0x16 + 0x8 + 0x4 + 0x2 + 0x1 = 0.
The largest binary number 1111 1111
represents 1x128 + 1x64 + 1x32 + 1x16 + 1x8 + 1x4 + 1x2 + 1x1 = 255.
The place value of the bold digit in the binary number 1011 0110
is 1x32 = 32.
