A MOOC is a free online course designed for large numbers of students from various geographic locations. They integrate social networking, online resources, and are facilitated by experts. MOOCs allow for self-organized participation based on learning goals and interests. Key advantages include no tuition fees, exposure to top professors, open access, and global collaboration. However, they can enable dropping out and limited feedback or real-world engagement due to large class sizes. Cloud-based learning delivers online education resources virtually via web-enabled devices, increasing flexibility, collaboration, accessibility via mobile devices, while reducing costs through an on-demand model where users only pay for what they use.
