, 27. The proliferation of technology has resulted in lower costs and
more choices. As a result, managers can lower costs by decentralizing
procurement and reducing centralized computing support. However, this
decentralization can increase management and support costs.
28. Local area networks are typically limited to a single premise
where all interconnections are implemented by and owned by the business.
In contrast, wide area networks typically involve multiple premises and
the interconnections must rely on access to public right-of-ways and
services provided by regulated common carriers.
29. In a circuit-switching network, a dedicated communication path is established
between two stations through the nodes of the network. That path is a connected
sequence of physical links between nodes. On each link, a logical channel is dedicated to
the connection. Data generated by the source station are transmitted along the dedicated
path as rapidly as possible. At each node, incoming data are routed or switched to the
appropriate outgoing channel without delay. The most common example of circuit
switching is the telephone network.
In a packet-switching network, data are sent out in a sequence of small chunks, called
packets. Each packet is passed through the network from node to node along some path
leading from source to destination. At each node, the entire packet is received, stored
briefly, and then transmitted to the next node. Packet-switching networks are commonly
used for terminal-to-computer and computer-to-computer communications.
