Exam 9: Network Organization Concepts

____ is an example of a circuit-switched network.

Typically,a host at one site,called the client,has resources that a host at another site,called the server,wants to use.

The objective of a hybrid configuration is to select among the strong points of each topology and combine them to meet that system's communications requirements most effectively.

If a collision occurs when using CSMA/CD,a jamming signal is sent immediately to both sending nodes,which then wait ____ before trying again.

In the routing information protocol (RIP),the entire routing table is updated only when changes have occurred; this decreases internetwork traffic and positively affects the delivery of messages.

When using the distributed-queue,dual bus (DQDB)protocol,transmission on each bus consists of a steady stream of fixed-size slots.

The TCP/IP reference model has ____ layers that roughly correlate to the OSI's seven layers.

Star topology permits easy routing because a central station knows the path to all other sites.

The maximum circumference for a MAN is ____.

When using the routing information protocol (RIP)to transfer data from one network to another,the path ____ is chosen.

In the virtual circuit approach to data transmission,the destination and packet sequence number are added to the information identifying the packet's message.

In a single loop ring topology network,each data packet is passed from node to node in both directions,and the destination station copies the data into a local buffer.

A common goal of all networked systems is to provide a convenient way to share resources while controlling users' access to them.

Carrier sense multiple access (CSMA)is a ____-based access protocol.

A router is an internetworking device,primarily software driven,which directs traffic between two different types of LANs or two network segments with different protocol addresses.

In the ____ topology configuration,hosts are connected to each other through a central controller which assumes all responsibility for routing messages to the appropriate host.

A local area network (LAN)is generally owned,used,and operated by a single organization and allows computers to communicate directly through a common communication line.

Token passing networks generally use either collision detection or collision avoidance techniques to deal with potential collisions.

In the distributed-queue,dual bus (DQDB)protocol,a node can use Bus 2 to send a ____ to its upstream neighbors.

In the ____ topology,all sites are connected to a single communication line running the length of the network.
