I need to find all the items (products) for a local area network for 12 users with a speed of 100 Mbps. A system that allows users to send and receive at the same time. I dont want a workgroup. All of the users also need access to high performance network printing. I need a brief description off all the products I need for this to work since two stores I have gone to have no idea how I can attain this and an estimated good price for all the products would also be aprreciated but is not necessary. Other than the microcomputers all of the pieces of equipment needed would be appreciated thanks in advance.
