trying to figure out network address usage

As a relative newcomer to networking, I am trying to straighten out my
understanding of the use of the network address (the one with all 0's
in the host section of the address). Is this address actually used to
contact a particular host or what, like putting it on the gateway
router somewhere? How is it used to find or contact the network?
Thanks for any replies.

My understanding (also learning)
Do you mean the subnet mask?
11111111.11111111.11111111.00000000

The zero's indicate the host address and the 1's indicate the network
address.

192.168.1.0 w/ mask 255.255.255.0
is a network address, not the address of a host
a host would normally be assigned an address between .1 and .254

If I got it wrong please chime in! I would hate to be saying (and
misunderstanding) something wrong..
 
Re: trying to figure out network address usage

You really just need to google for something like "subnet mask". There's a
bit of a learning curve, but its not a very difficult idea, for example:

Hope that helps,
