everything starting with the Penium Pro and AMD k6 including Pentium II/III/4, Athlon's, ect.

It is a vague cpu architecture label that basically means the (when put in a file name for a binary) that you can't run it on older processors like a K5, or a Pentium/Pentium MMX.

In a nut shell:

The different Intel CPU's
80386 - The oldest processor that linux can run on.
Pentium and compatable- i586
Pentium w/mmx and compatable- i686

In shorthand
i386 for 80386
You will also see x86 for Intel compatable

It basically references the CPU instruction set. Intel designed it to be downward compatable. Anything compiled for a i386 will work on a i686.
