I realize this is a very basic question but here goes...

What are the CPU designations expressed by:

    i286, i386, i486, i586, i686, etc.

I assume the first 2 are Pentium II and Pentium III respectively. What
specifically are the others? I have the latest  Pentium 4 with
hyperthreading. What is that CPU in this naming scheme?

Thanks in advance!
