What equipment must be purchased in order for each employee's computer to be connected to the network? (1.1) To start things off I would ensure that all of the cabling running throughout each building is sufficient for the networks. I would do this by ensuring that either category 5 Ethernet cable or Fiber cables are connecting the computers to the networks. A Star-wired bus topology is the easiest topology to install and maintain. The computers will each need network interface cards (NIC), I would I would suggest either a fiber NIC or Gigabit NIC which would provide 10/100/1000 Mbps auto-negotiation and centralized management over Category 5 or 5e UTP cabling-simplifying your migration to a Gigabit Ethernet later. We will connect the computers to switches which in turn will be connected to the servers and the servers will be connected to routers and then to the ISP via our T-1 connection.
What protocols will you need to set up on each server and on all of the workstations? (1.2a) Since you have both Windows and UNIX running over the same
