The paper outlines chapter six where Goleniewski focuses on local area networks and chapter seven where she discusses wide area networks. The paper describes how she divides chapter seven into two main subsections of circuit-switched networks and packet-switched networks, and posits that her descriptions of these three main types of networks help demonstrate how information moves from one host to another, both in local and wide area networks. The paper does point out, however, that the information on LANs and circuit-switched networks sounds pedantic if the future of the Internet is only packet-switched WANS.
From the Paper:"In chapter six, Goleniewski discusses local area networks (LAN). LANs are typically closed systems with a relatively small amount of users. LANs are generally made up of several key elements: network nodes, NICs, transmission systems, software and data, user interface, and an operating system (Goleniewski). Network nodes are addressable entities (Goleniewski). NICS are network adaptors that make it possible for computers to connect to the network (Goleniewski). Transmission systems perform the actual connections (Goleniewski). Software is how computers create data packets, which are what networks move from point to point (Goleniewski). User interfaces are the ways that users interact with the system (Goleniewski). Finally, the operating system runs the network (Goleniewski). LANs are generally grouped according to four characteristics: the types of transmission media over which they can operate, the transport technique that they use; the access method, and the mapping of the network (Goleniewski). The choice of transmission media is going to depend on bandwidth, cost and ease of connectivity, sensitivity to interference and noise, and security requirements (Goleniewski). Many LANs are baseband Ethernet LANs (Goleniewski). LANs can be accessed in different ways, including token passing and CSMA/CD. Token passing is a deterministic method that involves an active master inserting a specifically formatted packet into a ring; the token circulates around the ring, regenerated by each workstation it passes, until it reaches its destination workstation (Goleniewski)."
