Understanding basics of Weblogic .

What is a domain in Weblogic ?
Domain is logical grouping of resources and services and consist of Administration Server, Managed Server and cluster.  There can only be one administration Server in domain and zero to N Managed Server.

What is Administration Server ?
Administration Server is WebLogic Server instance that maintains configuration data for a domain. You can deploy your application on administration Server but it is recommended to create managed Server and deploy your application in managed server and leave Administration domain for configuration and maintenance.

—There will always be atleast one Administration Server in a domain.

Servers that are managed by Administration server , apart from main admin server are all Managed Servers.
