Exam 10: Management of Network Functions

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

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.

In a network operating system (NOS),____.

Each kernel is operated by the application software which,in turn,is directed by the kernel running on the host computer.

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

Networks were created initially to share data.

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

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

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

The Process Manager has responsibility for the following tasks: creating objects,dispatching objects,scheduling objects,synchronizing operations on objects,communicating among objects,and deleting objects.

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.

____ 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.

The focus of a network operating system is ____.

DO/S was developed before NOS.

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.

In a network operating system (NOS),the network management functions come into play only when the system needs to use the network.At all other times,the operating system operates as if it's a(n)____.

If a process requests access to a region in memory,the process manager determines whether the requesting process has been previously granted rights.

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.
