In the past, when we talked about educational resources, we first thought of universities and colleges, because they were places where we could learn more and improve our skills. Now, with the advent of the Internet, we have provided more open learning resources. When we want to learn some kind of skill, we can have more choices. For example, in the field of computer science, if you want to learn programming or its associated knowledge and skills, in addition to choosing a university or college,
