A node is an administrative grouping of application servers for configuration and operational
management within one operating system instance (virtualization allows multiple operating
systems on one machine).
A cell is a grouping of nodes into a single administrative domain.
In the Base and Express
configurations, a cell contains one node. That node contains one server.

The deployment manager is the central administration point of a cell, which consists of
multiple nodes and node groups in a distributed server configuration.
A proxy server is a specific type of application server that routes requests to content servers
that perform the work.
The web server plug-in
will send the request to the application server using the host name and port number in the
transport setting for that server.
An unmanaged node does not have a node agent to manage its servers.
If your web server is the IBM HTTP Server, you can
configure the server on an unmanaged node, and still be able to administer the web server
using the WebSphere administrative tools. This unmanaged node does not need a node
agent on the web server machine.
A managed node has a node agent for managing web servers.
