Processor question

I have a dell server (4600) I think. I have 2 xeon 2.4 ghz processors in it. Can someone tell me why it says there are 4 processors in taskmanager performance page? It also shows four if I select afinity for a process. I know I only have 2.

Thanks, Troy

Xeon processors are Hyperthreaded - Hyperthreading makes the CPUs appear to be 2 CPUs for each one installed.
Like in a single Pentium 4 machine.. Youll see 2 processors..  
mattisflones - that's not necessarily true.  There are P4 chips that DO NOT support hyperthreading.  Those will only be seen as one CPU by Windows.  Hyperthreading is key.
Like xeon`s without hypertreading...
