An online learning management system (LMS) is a software platform that helps educators create, manage, and deliver educational courses and training programs over the internet. It allows teachers to upload course materials, track student progress, and facilitate communication between students and instructors. LMS platforms often include features like quizzes, discussion forums, and grading tools, making it easier for both learners and educators to stay organized. Popular examples of LMS include Moodle, Canvas, and Blackboard, which are widely used in schools, universities, and corporate training environments.
