* Easier to manage than a P2P network
* More scalable than a P2P network
* Typically - More secure than a P2P network
* Accounts can be managed from one computer
* Resource rights can be easily granted to users or groups
* Network problems can be tracked, diagnosed and fixed from one location
* Servers are optimized to handle heavy loads and many requests
* Response times are typically faster
* A server can connect more than a handful of computers on a network
* The most popular type of network for medium to large networks
* Network+ covers mostly these types of networks

* Each computer can be configured to share only a part of its resources
* Simple and inexpensive to setup
* Not always as scalable or flexible
* Often less secure than a client server network
* Not as practical when connecting a large number of computers because they do not centralize resources
