Computer Systems Design and Architecture 2nd Edition
Heuring

This text has coverage of the developments in microprocessors, including ALU, pipelining, memory hierarchy, networks and the Internet. And, rather than focusing on a single type of architecture, Heuring and Jordan describe both CISC and RISC models at the ISA level using the formal description language of RTN (Register Transfer Notation), allowing for a more in-depth appreciation of different machine structures and functions.

Computer Networks 4th Edition
Tanenbaum

Tanenbaum takes a structured approach to explaining how networks work from the inside out. He starts with an explanation of the physical layer of networking, computer hardware and transmission systems; then works his way up to network applications. Tanenbaum's in-depth application coverage includes email; the domain name system; the World Wide Web (both client- and server-side); and multimedia (including voice over IP, Internet radio video on demand, video conferencing, and streaming media.
