During the Corona era, I took a lot of online classes on computers, and I was curious about the operating system, output, and overall computer concepts, so I signed up for the course. Since the explanations are pretty and clear, even non-majors can understand them well. Also, the voice when explaining is really nice ^^, so I can concentrate well ^^ I completed the course 100% 👍 The course period is unlimited, so I think it would be good to be able to watch the lecture again. I highly recommend the course 👍 I want to take other courses too.
