Processing and reporting
When the measurement code collects data, it packages that information up and sends it to Google Analytics to be processed into reports. When Analytics processes data, it aggregates and organizes the data based on particular criteria like whether a user’s device is mobile or desktop, or which browser they’re using.
But there are also configuration settings that allow you to customize how that data is processed. For example, you might want to apply a filter to make sure your data doesn’t include any internal company traffic or developer traffic.
