Read the Following description and draw the layered diagram. In a Google Drive/Docs Layered architecture, components are organized in layers. Components on a higher layer make down calls (send requests to a lower layer). While lower layer components can make up calls (send requests up), they usually only respond to higher layer requests. User-interface management Layer: You request to authorize your details. Interface layer: you request to see the latest doc from your drive. Processing layer: processes your request and asks for the information from the data layer. Data layer: stores persistent data (aka your file) and provides access to higher-level layers. The data layer returns the information to the processing layer which in turn sends it to the interface where you can view and edit it. While it feels like one cohesive process, it's broken down into three (or more) components on three distinct layers. Each layer may or may not be placed on a different machine
