Roland and Bob

I have glass fiber (100 MB/sec) that comes through one router which is not a 
NAT and has no firewall built in. I have been told that this is one hop from 
the backbone. I have attached the glass fiber to a modem, which gives me 
eight 10 MB/sec ethernet outlets. The modem is dumb and contains no firewall. 
That puts my computer two unprotected hops from the backbone (if I understand 
this correctly). 

One could say that I am exposed, without risking great exaggeration. But that 
doesn't matter, because there is really nothing on the machine. I am only 
using it to learn on. 

What does IMHO mean? 

What does h4x0r3d mean?
