This chapter has dealt with the low-level implementation of common data structures you'll find in various languages. For more information on data types, you can head off in two directions at this point - lower or higher. To learn more about the low-level implementation of various data types, you'll probably want to start learning and mastering assembly language. My book The Art of Assembly Language (No Starch Press) is a good place to begin that journey.
Higher-level data-structure information is available in just about any decent college textbook on data structures and algorithm design. There are literally hundreds of these books available covering a wide range of subjects.
For those interested in a combination of low-level and high-level concepts, a good choice is Donald Knuth's The Art of Computer Programming, Volume I: Fundamental Algorithms . This text is available in nearly every bookstore that carries technical books.
