Using a router on a small network

General question: You suggested to me in a previous posting to use a router verses the hub/sygate set up I currently have. Therefore, I must ask a dumb question:
Does a router act as a hub also to connect the 2 pc's together and share printers, hard drives, etc.?
I have a nic in each PC, use a Linksys 5 port hub and connect to a cable modem (@home). All is connected using sygate 4.0. I share printers and hard drives currently. I'm having some server recognition problems on the host so I'm considering the router move.

There are combination broadband routers/switches. For example, SMC makes two versions of the Barricade (http://duxcw.com/digest/Reviews/Network/smc/smc7004br/smc7004br.htm), which includes a 4-port or 8-port Ethernet switch in addition to the router function. With the 4-port version, you can plug 4 PCs in on one side of the box and your cable or DSL MODEM in on the other side. The PCs can then share the MODEM/Internet and do other Microsoft, etc. networking functions, such as share files and printers, just like they would if they connected to a hub, only better (http://duxcw.com/faq/network/hubsw.htm). Furthermore, a hub or switch can be connected to one of the Barricade’s PC ports to expand the network and provide Internet sharing to still more PC’s. There are other routers that do not include the PC ports. They can be connected directly to your existing hub, but I don’t think you would save much by buying one and you would have to have both boxes on to access the Internet. If you live in California, that could be a measurable expense. Larry
