I am charged to design a LAN for a private hospital. The client simply wants all the computers to be able to communicate with each other and also have a centralized control unit. He wants to use the Hospital management system software to keep all records and so on and also all the computers can access information from the software. What is the most effective way to go about that and also what do I need? E.g router, switch, server and so on. Also, I need help with the basic configurations. Thanks a lot.
