Distinguish "Timeout" and "Network Unreachable"

I often tested network using ping command.

When I test,displayed "Timeout" and "Network

Unreachable".

I understood if "Timeout" displayed,ICMP cannot

reach distination network cause of IP filtering or

Physical problem etc...

And if "Network Unreachable" displayed,cause of

routing-table problem.

Is this understanding correct?or if "Network Unreachable" displayed,can replied cause of

others?

The RFC answers it best. http://www.faqs.org/rfcs/rfc792.html
