An online course is a learning experience that takes place over the internet. It typically includes a series of lessons or modules on a specific topic, which may be delivered through various formats such as videos, readings, quizzes, assignments, and interactive discussions.
Online courses can be self-paced, allowing learners to complete the material at their own speed, or they can follow a structured schedule with set deadlines. They are often offered by educational institutions, companies, or individual experts and can range from free to paid, with some providing certificates or credits upon completion.
These courses offer flexibility, as learners can access the material from anywhere and often on any device, making them a popular option for professional development, hobby learning, or academic study.
