The technology that enables real-time collaboration in online documents typically involves cloud computing and web-based platforms. Tools like Google Docs and Microsoft Office 365 utilize these technologies to allow multiple users to work on the same document simultaneously, with changes reflected instantaneously. This collaboration is facilitated through services that manage user interactions, track changes, and enable communication. Real-time editing, version control, and commenting features enhance team productivity and streamlined workflows, making them essential for project coordination and remote collaboration in today's work environments.
