Network storage

This is the storage of data on a remote server. Unlike other means of storage we have talked about, this kind of storage utilizes a network connection to store and retrieve data that exists on a remote server. You utilized this storage medium when you created the messenger Android application in the previous chapter. The messenger application relied heavily on a remote server for the storage and retrieval of information. The client-server architecture is primarily in play when a remote server acts as a data source for a client application. The client sends a request for the data required (typically a GET request) to the server via HTTP, and the server responds by sending the required data as a response, thus completing the HTTP transaction cycle.
