Exam 9: Network Organization Concepts

When using a ring topology,a ____ can be used to connect to another network that uses the same protocol.

Circuit switching is a communication model in which a dedicated communication path is established between two hosts.

Addressing protocols are normally unrelated to the network topology and geographic location of each site.

Usually,the term "____" indicates a specific computer system whose services and resources can be used from remote locations.

A ____ includes information technology that operates within a radius of approximately 10 meters of an individual and is centered around that one person.

Which characteristic is true of packet switching?

A ____ is a device and software used to connect two or more local area networks or systems that use different protocols; it translates one network's protocol into another,resolving hardware and software incompatibilities.

The geometric arrangement of connections (cables,wireless,or both)that link the nodes in a networked system is called a ____.

Round robin access control is an inefficient technique when there are many nodes transmitting over long periods of time.

Under the Domain Name Service (DNS)protocol,in the address someone@name1.name2.name3.name4,the host name is ____.

In the OSI transport protocol model,Layer Seven,the ____ layer,provides the interface to users and is responsible for formatting user data before passing it to lower layers for transmission to a remote host.

The physical topology of a network may not reflect its logical topology.

When deciding which network topology configuration to use,designers should keep in mind four criteria: ____.

In a bus network topology,devices are physically connected by means of cables that run between them,and the cables pass through a centralized controller mechanism called the bus.

In the ____ path-selection approach,the destination and sequence number of a packet are added to the information uniquely identifying the message to which the packet belongs; each packet is then handled independently and a route is selected as each packet is accepted into the network.

The Transmission Control Protocol/Internet Protocol (TCP/IP)reference model is the basis for Internet communications and is the most widely used network layer protocol today.

Bridging between two homogeneous networks occurs at Layer 2 of the OSI transport protocol model,the data link layer.

The ___,which makes technical recommendations about data communication interfaces,took on the task of creating a universal network architecture,resulting in the OSI Reference Model.

The tree topology is a collection of rings.

Ethernet is the most widely known CSMA/CD protocol.
