It's annoying when I read text, like a book, and I see a mistake or typo. Gotta point it out. Mistake on page 338 of this hardback book: at the top it should say "(2^32)" not "(232)".

The book is titled "CompTIA A+ Certification All-in-One Exam Guide, Tenth Edition (Exams 220-1001 & 220-1002"; ISBN13 978-1-260-45403-1; 1524 pp.; 28 chapters; Chapter 9: Implementing Mass Storage; English; non-fiction; 2019; San Francisco; McGraw Hill Education; LCCN 2019007718; microcomputers, study guides, certification; Mike Meyers & Scott Jernigan

It also a chapter on how CPUs work, starting on page 79.
