Question 1

In response to the Write command,the File Manager sends a command to the remote server to unlock the specified file.

Accepted Answer

The File Manager typically sends a command to write data to the specified file, not to unlock it. File locking and unlocking are separate operations from writing data.

Question 2

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

Accepted Answer

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

Question 3

An object-based DO/S provides process management through the use of client/server processes synchronized and linked together through messages and ports,also known as channels or pipes.

Accepted Answer

An object-based Distributed Operating System (DO/S) primarily manages resources and provides services through the abstraction of objects, not necessarily through client/server processes, messages, and ports, which are more characteristic of communication in distributed systems or network operating systems.

Question 4

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

Accepted Answer

There is no such thing as DO/S (as far as we know), and even if there was, it is unlikely that all devices would be controlled by a single global device manager. Different devices may have different operating systems and require different types of management systems.

Question 5

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

Accepted Answer

The answer of If a process requests access to a...

Question 6

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.

Accepted Answer

The statement correctly defines the find-and-copy technique and why it is not considered true file sharing.

Question 7

In a network,the Processor Manager provides the policies and mechanisms to create,delete,abort,name,rename,find,schedule,block,run,and synchronize processes.

Accepted Answer

The Processor Manager is responsible for managing processes in a network and provides the policies and mechanisms for various tasks related to process management.

Question 8

One advantage of process-based DO/S is that the processes can be assembled to communicate and synchronize with each other to provide a distributed network of resources,with each process knowing the location of its distributed peers.

Accepted Answer

The answer of One advantage of process-based DO/S is that...

Question 9

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

Accepted Answer

The answer of The arbitration rule of a system scheduling...

Question 10

A DO/S must keep a global accounting of each network device and its availability,maintain each device's status record and control block,and distribute this information to all sites.

Accepted Answer

A DO/S (Director of Operations/Systems) is responsible for keeping track of each network device's availability and status as well as ensuring that this information is distributed to all sites to maintain efficient network operations.

Question 11

A distributed operating system does not need to deal with the possibility of deadlock caused by circular waits.

Accepted Answer

A distributed operating system still needs to handle the possibility of deadlock caused by circular waits, as distributed systems can still have processes or components that are dependent on each other and could potentially create a circular waiting situation.

Question 12

Networks were created initially to share data.

Accepted Answer

The answer of Networks were created initially to share data....

Question 13

Location transparency,the essence of cloud computing,is provided by mechanisms and directories that map logical data items to physical locations so that users don't need to be concerned with the physical locations of their files.

Accepted Answer

Location transparency is a key feature of cloud computing that hides the physical locations of data and resources from users, allowing them to access them as if they were local. This is achieved through mechanisms and directories that map logical data items to physical locations, ensuring that users don't need to be concerned with the underlying infrastructure.

Question 14

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.

Accepted Answer

In a distributed system, sites need to cooperate and share information in order to determine which process should be loaded and where it should be run, as all sites are interconnected and reliant on each other.

Question 15

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

Accepted Answer

The answer of Data redundancy can make files much faster...

Question 16

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.

Accepted Answer

This statement accurately describes the responsibilities of a Process Manager.

Question 17

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

Accepted Answer

A replicated kernel operating system allows for multiple instances of the kernel to be run simultaneously on different nodes in the network, ensuring high availability and fault tolerance. This is essential for managing a large and complex network with a wide range of resources.

Question 18

Execute-only access allows users to read the page; however,they are not allowed to modify it.

Accepted Answer

Execute-only access means users cannot read or execute code, but they can still modify it. Restricted or read-only access allows users to view the page but not make modifications.

Question 19

DO/S was developed before NOS.

Accepted Answer

NOS, or Network Operating System, was developed before DO/S. NOS was first introduced in the 1970s, while DO/S was developed by IBM in the 1980s.

Question 20

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

Accepted Answer

Each application software runs on the kernel, not the other way around. The kernel is the core component of the operating system that manages the system resources and provides services to the application software.
