Document Summary

Internet backbone: primary high-speed connections between large networks (long distance, networks connect through internet exchange points (ixps) Internet service provider: large telecommunication companies own the network, digital subscriber line (dsl) and fibre-to-the node (fttn, phone cables and fiber optics, requires modem, cable, television transmission signals, requires modem, mobile (hotspot) Multi-layered protocol hierarchy: explains the hierarchical flow of data through the internet. High level protocols (applications: rules for internet services and applications to exchange data, browser, email, each service has a set of protocols to follow and are hosted at a specific. Initial communication uses a specific network port network port. Transmission control protocol: ensure that data flows from the source to the destination, udp: emphasizes timeliness, so it does not request resending of. If there are errors in transmission, tcp requests the data be resent missing/corrupted data (by the time the data is resent, a new present frame will have been received: live streaming.
