The document outlines four basic types of eLearning platforms: Learning Management Systems (LMS) for course management, Virtual Learning Environments (VLE) for simulated learning experiences, Course Management Systems (CMS) for organizing course materials, and Collaborative Learning Platforms (CLP) that enable student and educator collaboration. Each type serves distinct functions, with examples such as Blackboard, Moodle, and Google Classroom provided for illustration. Overall, these platforms support the creation, management, and delivery of online courses.
