Costs and ConsiderationsNetwork ManagementOnce the network is in place someone has to manageall the updates, passwords, training, privacy, and backup.There are ongoing support costs. For every 50-75 usersthere should be one full time support person in placeto manage the network.
Costs and Considerations Cost Software Hardware Electronics Infastructure
Cost ConsiderationsReplacement of components Client Stations 18-36 months Network Electronics 3-5 years Infrastructure 10-20 years
