This is a book about how computers work. However, you must not arbitrarily assume that it is obscure and difficult to understand just because of words like "working principle". The author uses rich imagination and clear writing to explain the seemingly complicated theories in an easy-to-understand manner. You will not feel boring or stiff at all. More importantly, you will gain a deeper understanding of how computers work. This understanding is not at an abstract level, but has a certain depth, which is not even inferior to the understanding of "electrical engineers" and "programmers".
