Networking Fundamentals

Cloud-networking certs (AWS ANS-C01, Azure AZ-700, GCP PCNE, CompTIA CloudNetX) assume you already understand classical networking — OSI layers, TCP/IP, routing, the architecture of the modern internet. Network+ (CompTIA N10-009) tests those fundamentals directly. The book below builds exactly that foundation.
