QuestionAnswer
Name three Network Services Files Services, Print Services, Web Services
What is an Application Server? Application servers run certain software applications that can be accessed by users.
What is a Database Server? Computers dedicated to running database programs
Describe a Gateway A gateway is used to connect two dissimilar systems (such as an Ethernet and Token Ring network) and translate the data back and forth so two dissimilar systems can communicate.
What does a Router do? A router is designed to connect two or more network segments that may or may not be dissimilar. Routers provide alternate paths between network segments and can select the best path based on criteria such as line cost, line speed, and traffic load.
What is a Bridge? Segments a subnet by recording MAC addy and the associated segment where the device is located. A bridge is similar to a router in that it connects 2 or more physical network segments; segments connected by a bridge are one logical network segment.
What is a Firewall? A firewall filters traffic from the Internet
Define a Proxy? It hides your private network from the Internet and from public networks. A server running as a firewall can also be a proxy.The proxy server has clients connect to it to request a resource available on another server.

What is a Dedicated Application Server? A dedicated application server model has one physical hardware server and one application.
What is a Distributed Application Server? A distributed application server model is similar to a dedicated application model in that it is used for only one network application. However, in a distributed application server model, the network application is run on many servers concurrently.
What is a Peer 2 Peer? ? A (P2P) app server model is similar to a distributed app server -- multi instances of an application can be running on multi systems. Each system can run the apps as either a server, or as a client with the app being provided by another OS functioning a
