Client/Server Relationship
Designed with the concept of a client/server relationship. The client would request a starting page, and continue from there. Each document would have a unique resource identity, called a URL, or Uniform/Universal Resource Locator.
Given the starting idea of a web of documents, the connection between the client and server was built as a very simple identification of document information, so the server knew what to do. The only information the client needed to know was the URL, which contained the Protocol, Host, Port, and Resource Reference.
