E-learning platforms are online systems that provide educational content and resources to learners. They allow students to access courses, videos, quizzes, and interactive materials from anywhere with an internet connection. Popular examples of these platforms include Coursera, Udemy, and Khan Academy, which offer a wide range of subjects and skills. These platforms often feature tools for communication, such as discussion forums and chat options, enabling students to interact with instructors and peers. E-learning is convenient and flexible, making it easier for people to learn at their own pace and fit education into their busy lives.
