Exam 9: Introduction to Metropolitan Area Networks and Wide Area Networks

All wide area networks are collections of at least two basic types of equipment: a station and a ____.

A local area network works as a ____ network in that clusters of workstations are connected to a central point (hub or switch) through which workstations can transmit messages to one another.

Compared to Dijkstra's least-cost routing algorithm, the flooding technique seems more complex.

Many of the same technologies and communications protocols found in local area networks are used to create metropolitan area networks.

Local area network Ethernet allows users to set their own data transfer rates.

SONET rings typically have a failover time of ____ milliseconds.

____________________ is a data transfer service that can connect your business to another business (or businesses) using a standard Ethernet connection.

The speed at which a failover is performed is the ____________________.

A classic algorithm that calculates a least-cost path through a network is ____ algorithm.

You can assign many meanings to the weights in a weighted network graph.

Ciccuit-switched networks will someday replace packet-switched networks.

In a network graph, the edge between each pair of nodes can be assigned a weight or associated cost to form a structure called a(n) _________________________.

In a(n) ____________________ network, all data messages are transmitted using fixed-sized packages, called packets, and no unique, dedicated physical path is established to transmit the data packets across the subnetwork.

Any network is as strong as its strongest link.

Provide and explain an example of a circuit-switched network.

Almost all MANs are based on one of two basic forms of supporting technology: ____ or Ethernet.

A virtual circuit breaks a large amount of data into n packets.

When a node on a wide area network ____ network transmits its data, the data is received by all the other nodes.

When routing tables adapt to network changes, the routing system is called ____.

When a network or a part of a network becomes so saturated with data packets that packet transfer is noticeably impeded, ____ occurs.
