Google Drive is a file-hosting service and synchronization service developed by Google. Launched on April 24, 2012, Google Drive allows users to store files in the cloud (on Google servers), synchronize files across devices, and share files. In addition to a web interface, Google Drive offers apps with offline capabilities for Windows and macOS computers, and Android and iOS smartphones and tablets. 

Google Drive encompasses Google Docs, Google Sheets, and Google Slides, which are a part of the Google Docs Editors office suite that allows collaborative editing of documents, spreadsheets,  presentations, drawings, forms, and more. Files created and edited  through the Google Docs suite are saved in Google Drive.
