List the features of an e-learning system. Explain the features of any five synchronous tools that can be used for e-learning. Also explain the need of SCORM for e-learning.

Features of an e-learning system include:

1. Content Management: Organizing and delivering educational materials such as text, videos, and quizzes.
2. User Management: Managing user accounts, profiles, and access levels.
3. Assessment and Feedback: Creating and grading assessments, providing feedback to learners.
4. Collaboration Tools: Facilitating interaction between learners and instructors through forums, chats, and video conferencing.
5. Progress Tracking: Monitoring learners' progress, completion status, and performance.
6. Customization: Tailoring the learning experience to individual needs and preferences.
7. Mobile Compatibility: Accessing content and resources on various devices.

Five synchronous tools for e-learning are:

1. Virtual Classroom: Facilitates real-time interaction through video conferencing and chat.
2. Webinars: Conduct live presentations, lectures, and discussions over the internet.
3. Instant Messaging: Enables quick communication between learners and instructors.
4. Screen Sharing: Allows instructors to demonstrate concepts or guide learners through tasks.
5. Whiteboard Tools: Collaborative digital whiteboards for brainstorming, drawing, and problem-solving.

SCORM (Sharable Content Object Reference Model) ensures interoperability and reusability of e-learning content across different learning management systems (LMS). It defines standards for packaging and describing e-learning content, enabling seamless integration and tracking of learner progress across various platforms.
