Mobile application requesting data
Similar to how the browser requests a web page from the web server, a mobile application can request data in JSON or XML format from the application server via HTTP or HTTPS. It uses the same protocol to send similar types of requests with headers followed by two new line characters and gets a reply back in the same format with headers followed by two new lines and data as plain text in JSON format.
JSON is a lightweight data format used to exchange data on the web by mobile, desktop, and web applications. It stands for JavaScript Object Notation and is easy to read and write as it is in plain text. It has become the de facto format for exchanging data on the web and for mobile applications, and has quickly replaced XML as a medium for exchanging data.
