Exam 2: Lan/Wan Interconnectivity

____ is the process of transmitting a data-carrying packet over radio waves through short bursts.

Token ring is defined through the IEEE 802.3 specifications.

The P in PDU stands for ____.

____ is a process used by routers that involves gathering information about how many nodes are on a network and where they are located.

____ does not guarantee the most efficient use of the network medium, because transmission occurs on only one channel at a time.

When using FDDI, it is possible for several frames from several nodes to be on the network at a given time.

Broadcast storms are more common on token ring networks than on Ethernet networks.

____ are used least frequently on networks.

What is a redirector? What OSI layer is it used in?

Flow control software and capabilities are found in the ____ layer of the OSI model.

Throughput is the transmission capacity of a communications medium, which is typically measured in bits per second or hertz, and which is determined by the maximum minus the minimum transmission capacity.

Modern networks combine the logical communications of a(n)____________________ with the physical layout of a(n)____________________.

Two computers can communicate within a LAN or across a WAN even if they are not both operating under the same communication model.

Each token ring network designates one node as the ____________________, which is responsible for packet timing on the network and for issuing new token frames if problems occur.

Discovery is the process of checking communication cable for a specific voltage level indicating the presence of a data-carrying signal.
