How to connect a virtual machine to the internet (vmware)?

I have windows 7 64bit as my
native OS (as of now). I am trying to
run windows xp professional 32bit and again 7 on
a vmware virtual machine.
Everything is working perfectly,
except I cannot figure out how to
connect to the internet.
I know nothing about internet
connections or terms. NAT, host-only,
TCP, these all go over my head. I
know nothing. Please, can you
explain in layman's terms how to
connect to the internet from the
virtual machine?

Also please tell me that in my laptop
window the data usage will be
considered under vmware workshop 10
or under the softwares in virtual
machine....
My laptop has windows 7 and i installed
7 and xp in vmware for testing purposes.........


ps. I am connecting to a secured
network via wi-fi. (i could connect to
an unsecured network if i really had
to, but i'd prefer not to have to)

I also want to know that does vmware uses internet via host windows or directly connects to wifi....
In second case i can't connect to wifi because i will have to register the new mac address.... So does it uses Internet via host window or not...?

whs said:

You connect like on a real machine - no difference.

Ok i don't want to connect to physical network just use the Internet provided to the host window.... So which options should i use.... NAT or host only
