Thank you for leaving a good review. There are more people like kjk2875 who are suddenly assigned to IT management positions in companies even though they are not IT management positions. This lecture video was created to help those people, and I am really grateful that you made it fun and even completed it. I am glad that it was helpful. Also, I am preparing an advanced version of this basic lecture. Currently, the curriculum has been released and the materials are being created. Since I have to create the materials, produce the video, and register the lecture, it seems like it will take a while. The goal is to open it in the first half of the year, and I will work hard. This advanced lecture will be created by inviting an expert who has been managing IT infrastructure in the field for over 15 years, and I will act as a student and have him act as the instructor. I will prepare it with in-depth practical knowledge about the work that is actually done in the field, so please look forward to it. :) In addition, if you have questions while working but don't have a place to ask, ask them on the SharedIT Q&A bulletin board. Since veteran experts with over 10 years of experience will provide many answers, you will be able to get a lot of help in your work.
