Document Summary

Study questions: summarize the functions of the five layers of the hybrid network model and describe the major tcp/ip protocols used at layers 3, 4 and 5, application layer: layer 5, service, governs how apps work together. Must convert all info to bits: transport layer: layer 4, packets are called segments, tcp and udp used here, fixes problems and does fragmentation and assembly. Uses port numbers: internet layer: layer 3, ip protocol is used here, data link layer: layer 2, physical layer: layer 1, governs transmission through single networks. Converts bits to electric signal: ethernet and wi-fi operate at layers 1 and 2. They are the physical delivery vehicles for network packets: (cid:498)interesting stuff(cid:499) happens at l3-5/7, layer 2 networks are good at providing fast packet transmission. Divided into four segments: what is dotted-decimal notation, dotted decimal notation is, what is the difference between a public and a private ip address, and public ip address is assigned by icann.
