Host-only networking in VMware Workstation creates a network between all virtual machines (whose network type is set to host-only as well) and the host computer computer (in your case, your Windows 8 machine).
This link provides more information on the topic of host-only networking.
If you're looking to provide internet connectivity, you can use either NAT Networking, or Bridged Networking.
NAT Networking will provide your GOS (Guest Operating System) with an IP that is NAT'ed from your Host. Bridged networking will allow your GOS to obtain an IP from your physical network (provided there's a DHCP -- usually your wired (or wireless) router serves as the DHCP server in most home networks). Hope that helps!
