i'm using a broadband connection and i don't have a router. but on my config. there is still a gateway IP address. does all connections have a gateway address?

Yes they do. When you browse to an address that is not on your local network then your computer forwards the request to the gateway address.
Without a gateway address you would not be able to browse the web.

All internet connections have a gateway address, even if you do not have a router in place somewhere along the way there is going to be a modem or something that the connection is passing thru.
If you go to your start menu, then select 'Run...', and then open 'cmd' (if you are running an older version of windows you may need to enter 'command').
When the 'black' window pops up enter 'ipconfig' and then press enter. this will give you all the info on your connection.

your broadband modem (either cable or DSL) has a built in router. this is how your local computer(s) on your LAN access the Internet. all IP network connections must use routing to get from one network to another.
here is an example:
computer A has a IP network address of 192.168.1.10. that computer resides on the 192.168.1.0 network, essentially A's location is .10 on that network. computer B has a network address of 192.168.1.2. since A & B are on the same network (192.168.1.0) they do not need a router to communicate with each other.
computer C has a IP network address of 192.168.2.25, it is on the 192.168.2.0 network. in order for A to communicate with C the traffic must be "routed" from one network to the other. the default gateway is the address of the interface by which traffic sent from A must use to get to C
A
IP address of 192.168.1.10
default gateway of 192.168.1.1
B
IP address of 192.168.1.2
default gateway of 192.168.1.1
C
IP address of 192.168.2.25
default gateway of 192.168.2.1
IP router
Interface 1 has an IP address of 192.168.1.1
Interface 2 has an IP address of 192.168.2.1
so for A to send data to C the connection looks like this:
192.168.1.10 ---> 192.168.1.1 (router interface 1) --> 192.168.2.1 (router interface 2) -----> 192.168.2.25
and just the opposite for C to send data to A
192.168.2.25----> 192.168.2.1 (router interface 2) --->192.168.1.1 (router interface 1) ------> 192.168.1.10
so the default Gateway for A would be 192.168.1.1 and for C the default Gateway is 192.168.2.1

In telecommunications, the term gateway has the following meanings: *In a communications network, a network node equipped for interfacing with another network that uses different protocols. *#A gateway may contain devices such as protocol translators, impedance matching devices, rate converters, fault isolators, or signal translators as necessary to provide system interoperability. It also requires the establishment of mutually acceptable administrative procedures between the two networks. ...

yes. All connections will have a gateway and a subnet mask. Even if you do not have a router putting out wireless for subnets to grab onto.

go to start, run, type in cmd, then type in the black box ipconfig and it will give you everything you are asking for.
