another device manager
If the local device manager cannot satisfy a user's request, the request is sent to ________.
exchanging messages between site operating systems
In a distributed system, there is a high level of cooperation and sharing of actions and data maintained by the sites when determining which process should be loaded and where it should be run; this is accomplished by _________.
long on to the local network
In a typical NOS environment, a user who wants to run a local process at a remote site must first ________.
Seven
In the OSI model, Layer ______ provides the interface to users and is responsible for formatting user data before passing it to the lower layers for transmission to a remote host.
host-host
In the TCP/IP model, the ______ layer is equivalent to the transport and session layers of the OSI model.
star
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.
icarus
In the address [email protected], the host name in this address is _________.
Running
Once an object has been scheduled, the Process Manager must wait for the kernel dispatcher to pull it out and place it into the _______ state.
WLAN
The _______ is the most vulnerable to security breaches.
Find and Open
The ________ file function causes the DO/S File Manager to use a master directory with information about all files stored anywhere on the system and set up a channel to the file.
that it does not take global control over management functions
The biggest limitation of a NOS is _______.
MAN
The distributed-queue, dual bus (DQDB) protocol is intended for use with a dual-bus configuration, where each bus transports data in only one direction, and has been standardized by one of the IEEE committees as part of its ______ standards.
topology
The geometric arrangement of connections (cables, wireless, or both) that link the nodes is called a _________.
four
There are ______ layers in the TCP/IP model.
decision mode
Typically, the system's scheduling function has three parts; a ________, a priority function, and an arbitration rule.
site
Usually, the term _______ indicates a specific location in a network containing one or more computer systems.
spooler
When a user wants to print a file by executing a print command the user's File Manager places a copy of the file in the DO/S ______ directory.
page fault
When an application tries to access a page that is not in memory, a ______ occurs and the Memory Manager automatically brings that page into memory.
basic cost, communication cost, reliability, and user's environment
When deciding which configuration to use, designers should keep in mind what four criteria?
a random period
When using CSMA/CD, and a collision occurs, a jamming signal is sent immediately to both sending nodes, which then wait ______ before trying again.

_______ is a good example of a circuit-switched network.
Shared by many transmissions
________ is true of packet switching.
Resources are owned by local nodes.
_________ is true of a NOS.
Concurrency control
__________ techniques give the system the ability to perform concurrent reads and writes, as long as the results of these actions don't jeopardize the contents of the database.
