Final answer:
The correct abbreviation for CMS is 'Content Management System,' which is a software for creating and managing digital content used in enterprise content management and web content management.
Step-by-step explanation:
The correct abbreviation for CMS in the context of digital platforms is "Content Management System." A Content Management System is a software application or set of related programs that are used to create and manage digital content. CMSs are typically used for enterprise content management (ECM) and web content management (WCM). An ECM facilitates collaboration in the workplace by integrating document management, digital asset management, and records retention functionalities, and providing end-users with role-based access to the organization's digital assets. A WCM, on the other hand, powers websites and allows non-technical users to easily create and manage website content.
