Before the beginning of this semester, my goal was to improve my understanding of computer through tis courses. Through this semester's study of this course, I have more understanding of the computer, I will also engage in some computer work in the future, and then I can effectively use the knowledge I have learned. Here, I would also like to thank my teacher Hairudin, who conscientiously imparted knowledge to us in every class and carefully answered our questions when we were confused. Moreover, she would ease the classroom atmosphere every day so that students could finish every class happily.
