Along with reading, writing, and arithmetic, computational thinking is an essential skill that everyone living in the AI era must possess. Simply put, computational thinking can be defined as thinking like a programmer or a computer scientist. This course replicates an actual full-semester university lecture and covers essential content for those new to programming or beginners planning to major in computer science. Furthermore, through this course, non-computer science majors or those with a background in the humanities can develop the ability to communicate easily with professional programmers. Even in an age where learning prompts for "AI vibe coding" is necessary, computational thinking will help you develop the ability to instruct AI more accurately and effectively.

This lecture explains the principles of computer architecture, which is the knowledge underlying programming, for non-majors. The goal of the lecture is to become familiar with the principles of program operation.

I will transform the Engineer Information Processing written exam (Subjects 1–5) from a "test you solve by memorizing" into a "test where you connect clarified points directly to your score." This is an ultra-compressed lecture designed to help you grasp the entire flow within 3 days. It extracts only the core concepts repeated in past exams, structured to be understood even if viewed right before the test. The course is designed for short-term success by clearly distinguishing between frequently confusing concepts, trap points in multiple-choice options, and what needs to be memorized versus what only needs to be understood. "I'm short on time, but the scope is too broad." "I feel like I know the material when reading the book, but I keep getting the questions wrong." This lecture is for students facing these exact challenges.

You can learn about the basic structure and operating principles of computer hardware, design methods, and OS, and acquire the knowledge necessary to create good programs.

This is exactly why we haven't succeeded until now. It's because of our perspective on the world. Let me ask you something. To succeed, you need to work hard, right? Wrong! You're mistaken! This is why it didn't work out. You don't need to work hard. You're probably thinking this sounds ridiculous, right? Let me explain. What do you feel when you think about working hard? I'm going to do this passionately! Even while having these thoughts, you feel a strange burden. That burden! A burden already forms inside you. This is how the unconscious mind operates. When you think of A, it brings out B. And it ends up making you maintain your current level. That's right. The word "hard" is associated not with passion, but with burden. What's been programmed in our collective unconscious is that the word "hard" seems related to passion, but it's actually related to burden. Now let's remove the word "hard" from our perspective on the world.
