The Architecture of Computer Hardware, Systems Software, & Networking by Irv Englander offers a clear, accessible introduction to the core components of computer systems. It covers hardware, operating systems, and networking in a way that’s beginner-friendly but still detailed enough for IT students and professionals. The real-world examples and structured layout make complex topics easier to understand. While some readers noted the lack of a glossary and lower paper quality in the paperback, most agree it's a well-written and valuable resource for learning how modern computing systems work.
