Now to the heart of the matter:
If you want to understand how a computer works from the silicon up, Patt & Patel is superior to CS:APP in the hardware fundamentals. If you want to optimize C code on Linux, CS:APP is better. | Used copies cheap | | MIT OpenCourseWare: 6
Unlike many introductory texts that treat hardware and software as separate entities, Patt and Patel bridge the gap. By the end of the book, a student doesn't just know how to write a "Hello World" program in C; they understand exactly how those characters are stored as bits and how the CPU processes each instruction. If you want to optimize C code on Linux, CS:APP is better
