Hate to disagree, but I think you really wanted a Router, probably with a
firewall built it, and possibly with wireless capabilities as well.

Typically, the service provider only allows you to have a single IP address,
usually dynamically assigned. They think that corresponds to one computer.

The router will do NAT, making all the internal computers look like one
external one. It will also limit how much of your internal network is visible
from the outside. Most routers also include a 4-port switch.

Prices are under $100 US.

Some routers even have embedded linux internally, and there are projects that
allow custom versions of linux with special features. See OpenWRT.org

What you need to find out is what's connecting the other two users to the internet connection at the moment, a router may well be in place already.

If your connection is not high speed then this may all be purely academic.

The Hub or Switch decision will have little impact on an internet connection smaller than approx 4.5 Mbps, which is the theoretical maximum you can get from a 10 Mbps half duplex hub (The Hub equivalent of the lowest for of life). A Switch will give you a "dedicated" or rather switched 100 <or insert switch port and corresponding NIC speed here> Mbps across the LAN, but you can never achieve 100 Mbps over an internet connection which is not 100 Mbps or more in capacity so having a 100 Mbps link to it .

A Switch will however let you copy files from one PC to the Other more quickly, so for that size of network it can't really hurt A firewall is also a VERY good idea, some might even say essential.
