Document Summary

Generally, we have two types of networks regardless of the topology: peer-to-peer network; in this fashion, there is no dedicated server. Workstations are connected to each other without a centralized server to manage services. Say you share a printer between multiple work stations in bus topology. Recall that in peer-to-peer the maximum number of nodes which can be connected is (node = any device with an ip) ten. Each computer is a client and a server, but they are very active" clients and passive" servers: client/server network. The server is the centralized manager and can have an unlimited number of clients. So, at the heart of this system there is a dedicated server. The server uses special operating systems: windows 2003, 2008, unix, linux(?). The dedicated server is running a nos (network operating system). Client/server network requires an existing network infrastructure (topology). Though we have numerous topologies, the most popular topology today is: .
