If you want to connect multiple PCs to the Internet you'll need a
router, which also forms the basis of your Local Area Network (LAN) i.e.
it provides a DHCP server to define a LAN address, provide network
addresses to your PCs, and other good stuff.

May I suggest a router which is firmware upgradeable - IPV6 approaches!

My router only has four Ethernet sockets, so to connect more than four
machines a switch is required to expand the number of connections.
According to what I understand, a switch performs pretty much the same
function as a hub but in a more intelligent fashion.

The router is the part that may require setting up, and that requires
some networking knowledge.

No, but if you want to run any sort of corporate email, web site, etc.
you'll want something that runs 24/7 i.e. a server that it protected by
a UPS etc.
