____ area networks can cover large geographic distances,including the entire Earth.

A(n)____________________ is a collection of nodes and interconnecting telecommunications links.

When all the routing information is in one place,it is difficult to make updates to the routing information.

A(n)_________________________ is a collection of computers and computer-related equipment interconnected to perform a given function or functions and typically using local and long-distance telecommunications systems.

In ____,before one node sends a series of n packets to another node,the sending node inquires in advance whether the receiving node has enough buffer space for the n packets.

A(n)____________________ is a device that allows one or more stations to access the physical network and is a transfer point for passing information through the network.

The path in a circuit-switched network exists only in the software.

____ applications do not negotiate a connection,and the transfer of data is rarely,if ever,acknowledged.

A ____ profile describes various characteristics about the connection,such as basic data transfer rates,basic burst rates,excess data transfer rates,and excess burst rates.

The type and number of interconnections between nodes and the way network data is passed from node to node are the responsibility of the ____.

Briefly explain the most important aspects of a Metro Ethernet.

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)_________________________.

A(n)____________________ network application does not require a logical connection to be made before the transfer of data.

A network that expands into a metropolitan area and exhibits high data rates,high reliability,and low data loss is called a(n)___________________________________.

With _____________________________________________,the frame relay router experiencing congestion sends a signal back to the originating station,which then slows down its transmission.

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

A(n)____________________ is a device that a user interacts with to access a network,and it contains the software application that allows someone to use the network for a particular purpose.

The SONET network topology is a ____.

The ability to reroute in the event of a failure is called ____________________.

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