Exam 9: Network Organization Concepts

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

The Internet layer is equivalent to the data link layer of the OSI model.

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

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.

When using RIP the entire table is updated only when changes have occurred; this decreases internetwork traffic and positively affects the delivery of messages.

When using a bus topology, ____ sites can successfully send a message at a time.

In the TCP/IP model, the ____ layer is equivalent to the transport and session layers of the OSI model.

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.

The IEEE standard 802.11b is not compatible with 802.11g.

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

Usually, the term "____" indicates a specific location in a network containing one or more computer systems.

A ____ is typically a cluster of personal computers or workstations located in the same general area.

In a bus 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.

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

____ is true of packet switching.

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

The tree topology is a collection of rings.

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

A MAN is a high-speed network often configured using a physical ring topology.

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