Exam 10: Management of Network Functions

In a network operating system (NOS),____.

In ____ communication schemes,the sender and receiver are linked and ready to send and receive.

____ techniques in an object-based DO/S 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.

Most networks are homogeneous;that is,they support computers running a wide variety of operating systems.

The major difference between a NOS and DO/S involves ____.

Under a DO/S,resources are allocated based on negotiation and compromise among equally important peer sites in the distributed system.

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.

Data redundancy can make files much faster and easier to read.

In a typical NOS environment,a user who wants to run a local process at a remote site must first ____.

The arbitration rule of a system scheduling function is a policy that is used to resolve conflicts between jobs of different priorities.

The find-and-copy technique isn't considered true file sharing because all users wanting access to the data file must copy the file onto their own systems,thereby duplicating the code and wasting space.

To control resource clusters as a group,most process-based systems are configured around complex ____,which manage multiple resources or divide the work among subordinate processes.

In process-based DO/S,resources are controlled by servers called ____ that are responsible for accepting requests for service on the individual devices they control,processing each request fairly,providing service to the requestor,and returning to serve others.

To globally manage the network's entire suite of resources,a DO/S is typically constructed with a replicated kernel operating system.

In an object-based DO/S,if the local device manager cannot satisfy a user's request,the request is sent to ____.

Typically,a DO/S system's scheduling function has three parts: a ____,a priority function,and an arbitration rule.

In a DO/S,the ____ is responsible for process synchronization mechanisms and communication support.

All devices are controlled by a global device manager under a DO/S.

The focus of a network operating system is ____.

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.
