Logarithm

So here's an interesting topic and one I think I'll remember because I already half know it under another guise.

The reason I'm posting about logarithms is because wireless networking uses a logarithmic scale in decibels. Binary is also a logarithmic scale.

Logarithm is essentially the power of, or "base". For example the logarithm of binary is base 2.

For example:
Log10 (1000) = 3 - You read this as Log of 1000 to base 10 is 3 - 10 x 10 x 10 = 1000 = 10 power3
