I would like to purchase a computer sytem for a new office. Three computers will be netowrked togeth

I will need a router. There are certain requirements from the software for the hardware....do they mean all three computers or just the router to support the software. If there is a router to connect all three computers how do people in other offices get the internet wirelessly. Do we need a wireless router. AND what kind of computers Dell? Compaq? HP? and a service department not in India (are there any?) Thanks

Dell are ok.

If you think you might expand your network in the future then you need a server. This contains the software and the 3 PCs access the server. The server is also connected to the Internet with firewall.

You might be better off hiring a company that does networking.
HP's service department is in a country south of the Himalayas. Their computers are good, but their tech support would be better if they used Answers - I've seen better technical expertise here - from people who can't have graduated from high school - than I've gotten from HP Tech Support.

If you want internet connectivity, you'll need a router - whether you want to use wireless or not is your choice, but wired is faster (between computers - wireless is still far faster than your internet connection), more secure and easier to maintain. (Just look at all the "I get limited connectivity on wireless" questions here.) If all you want is to connect the computers to each other, all you need is a switch or hub, although you won't save much by not buying a router - maybe $25.
