• The client-server-DNS-routing-packet layer model of a network request
• The distinction between a protocol (a rule set) and physical network infrastructure
• Packet reassembly using sequence numbers despite out-of-order arrival
• TCP’s retransmission/reliability guarantee as the cause of differing outcomes between two contrasted network scenarios
• Bandwidth, latency, and fault tolerance as distinct causes of network performance problems
• The real end-to-end sequence of network layers for a specific, novel URL
• Application of the layer model (client, DNS, routing, packet, server) to an unfamiliar, real-world infrastructure failure scenario
• Accountability for harm in a decentralized network, applied to a specific real incident not covered in class
• The function of DNS as name-to-address translation
• Packet-switching’s fault-tolerance advantage over single-stream transmission, as an integrated explanation

Every lesson is written for a parent with no teaching background: it opens with a short script to read aloud, names the specific wrong idea a student is likely to reach for and how to correct it, and closes with a practice sheet you may copy for your household. Scripture references are King James Version throughout. Black-and-white, 8.5 x 11 in. The whole year of this course is also in this store as a single book.
