Okay, quicky explanation using really ugly formating...=)

The logical OR means is any of the coninciding bits are set they are
flagged.
When you saw "or" you mean one or the other, so if one of the other bit is
set
its true...plain simple english, all computer languages are at some level or
symbol.

[ 0011 ]  |
[ 0110 ]
--------becomes
[ 0111 ]
--------cause either bit has to contain a 1.

The XOR or exclusive OR means only if they are different.
So think of the word "exclusive", like an exclusive restaurant, only certain
cases
can get in.  So OR's are not allowed in, cause only the ones where they
are exlusively different can get in.  Cause "or" is one or the other.  So it
like saying "you
gotta be one or the other exclusively to get in my restaurant bub!"

[ 0011 ] ^
[ 0110 ]
--------becomes
[ 0101 ]
--------cause they are different.
