What kind of Linux is this?

[prasath_digit]

I'm running a copy of the Fedora 9 (Sulphur) which is bundled in this month's DVD. I want to install

1. Java Development Kit 6 Update 6 for developing Java programs ( & running out of time )

My CPU is an AMD Athlon 64 X2 3600+ [Dual-Core] [64-bit]

I went to sun's website to download jdk, it gives either an i586 (OR) x64 version. I don't know which version to download.........Because the System Info in fedora 9 shows that my copy is i686.........What is i686?.........whats the diff between i586 & i686 & x86-64?...........My CPU is an x86-64 Arch right?.........Is i686 32-bit or 64-bit?..........

Which version should i download?

And what is the convention used for a:

1.32-bit Version of Linux
2.64-bit Version of Linux

plz HELP I'm TEARING MY HAIR OUT...................

You're saying the complete opposite. i686 is meant for Pentium-II and upwards (P3, P4, onwards ...) and is no-way "backward-compatible" on architectures dating before it (aka 80386, 80486 and i586 (Pentium)).
