Is The RPC a Protocol or a winXP-Service?

[Mr Babak Memari <memari () mail15 com>]

What is The RPC exactly  ?
The RPC  is a Protocol  or a winXP-win2000-Service or a Port?
www.Rabertgraham.com  says that it is a Protocol .
My windows says it is a Service .
Some other articles says that it is a Port .

And another questions :
www.Rabertgraham.com in its FireWall-FAQ  says these lines:

[""Various errors with 127.0.0.1 :
Some servers are misconfigured to map this address.
On the other hand, it is also a hacker technique
to cause names within the hacker domain to resolve
to addresses within a company (including localhost/127.0.0.1).""]

And my question is :
How do they (Crackers) do that ?
