Question 3

A(n)____ is the record of a user that contains all of his properties,including rights to resources,password,name,and so on.
A) shell
B) container
C) account
D) directory

Accepted Answer

A user account contains all the necessary information about a user, such as their username, password, access rights, and other properties. A shell is an interface between the user and the operating system, a container is a virtualization technology, and a directory stores and organizes files and folders. None of these options accurately describe a user account.

Question 4

A benefit to using an NTFS partition is that it can be read by older operating systems,such as Windows 95,Windows 2000 Professional,and early versions of UNIX.

Accepted Answer

NTFS is not supported by older operating systems like Windows 95 or early versions of UNIX. It was introduced with Windows NT 3.1 and is compatible with newer versions of Windows and some Linux distributions.

Question 5

In every NOS,groups form the basis for resource and account management.

Accepted Answer

Groups are essential for resource and account management in most network operating systems (NOS). Groups enable administrators to manage resource access and permissions by assigning users to groups with specific privileges. Group policies can also be applied to multiple users simultaneously, simplifying the management of large networks.

Question 6

The core of all UNIX and Linux systems is called the kernel.

Accepted Answer

The kernel is indeed the core of all UNIX and Linux systems, providing the essential services for other programs to run and interact with the hardware.

Question 7

The printer queue is a ____ representation of the printer's input and output.
A) virtual
B) logical
C) physical
D) hierarchical

Accepted Answer

Accepted Answer

The answer of ____ is one of the most important...

Question 9

A(n)____ is a pictorial representation of computer functions that,in the case of NOSs,enables administrators to manage files,users,groups,security,printers,and so on.
A) snapshot
B) shortcut
C) icon
D) GUI

Accepted Answer

A GUI (Graphical User Interface) is a pictorial representation of computer functions that allows users to interact with the computer system. In the case of NOSs (Network Operating Systems), GUIs enable administrators to manage files, users, groups, security, printers, and other network-related tasks.

Question 10

A(n)____ is a routine of sequential instructions that runs until it has achieved its goal.
A) process
B) thread
C) activity
D) job

Accepted Answer

A process is a sequence of instructions executed by a computer system's operating system to run a program. It runs until it has achieved its goal, which is the completion of the program. Threads are smaller units of a process, activities are typically used in project management, and a job can refer to any work assignment, not necessarily a sequence of instructions.

Question 11

Active Directory organizes multiple domains hierarchically in a domain ____.
A) OU
B) directory
C) tree
D) bucket

Accepted Answer

Active Directory organizes multiple domains hierarchically in a domain tree. This hierarchy starts at the root domain, which is also known as the forest root domain, and branches out into child domains. The domain tree provides a way to partition the namespace and delegate administrative control over each branch of the hierarchy. A domain tree can contain multiple domains, and each domain can have multiple organizational units (OUs) for grouping resources and delegating administrative control.

Question 12

A workgroup is a group of interconnected computers that share each other's resources without relying on a central ____.
A) OU
B) domain
C) database
D) server

Accepted Answer

A workgroup does not rely on a central server to share resources. Instead, each computer in the workgroup can share its resources with other computers in the same workgroup. Therefore, the best choice is D - server.

Question 13

The term ____ memory refers to the RAM chips that are installed on the computer's system board and whose sole function is to provide memory to that machine.
A) virtual
B) logical
C) physical
D) hierarchical

Accepted Answer

Physical memory refers to the actual RAM chips installed in the computer, as opposed to virtual memory which is a portion of the hard drive used to supplement the RAM. Logical memory and hierarchical memory are not related to the specific memory chips installed on the system board.

Question 14

____ memory may be logically carved out of space on the hard drive for temporary use.
A) Virtual
B) Logical
C) Physical
D) Hierarchical

Accepted Answer

Virtual memory is a technique where a portion of the hard drive space is used as an extension of the computer's physical memory. This way, the computer can run more programs than its physical memory can support. The virtual memory system logically carves out space on the hard drive for temporary use, but it still needs to move data in and out of physical memory as needed, which can slow down system performance.

Question 15

A(n)____ is a self-contained,well-defined task within a process.
A) task
B) thread
C) activity
D) job

Accepted Answer

A thread is a self-contained, well-defined task within a process.

Question 16

The support and use of multiple processors to handle multiple threads is known as ____.
A) multiprocessing
B) multitasking
C) multithreading
D) multisharing

Accepted Answer

Multiprocessing refers to the use of multiple processors to handle multiple threads, which is the most appropriate option given. Multitasking refers to the ability of an operating system to run multiple applications or processes at the same time. Multithreading refers to the ability of a program to run multiple threads within a single process. Multisharing is not a recognized term in computer science.

Question 17

The term domain model refers to a type of peer-to-peer network that relies on domains rather than on workgroups.

Accepted Answer

The term domain model refers to a representation of the real-world concepts and rules within a specific problem domain, often used in software engineering and object-oriented programming. It is not related to peer-to-peer networks or workgroups.

Question 18

A(n)____ is a list that organizes resources and associates them with their characteristics.
A) file inode
B) container
C) account
D) directory

Accepted Answer

A directory is a list that organizes resources (such as files) and associates them with their characteristics. It is like a folder in a file system that helps to group and organize files in a logical manner. A file inode is a data structure used by some file systems to store information about a file, but it is not a list that organizes resources. A container is a way to group related items together for easier management, but it is not specifically used for organizing resources and their characteristics. An account is a user's personal space on a system with associated settings and permissions, but it is also not specifically used for organizing resources and their characteristics.

Question 19

In UNIX,you combine commands using a pipe,which is entered as a forward slash ( / ).

Accepted Answer

In UNIX, you combine commands using a pipe, which is entered as a vertical bar or pipe symbol ( | ), not a forward slash (/).

Question 20

The process of copying directory data to multiple domain controllers is known as ____.
A) replication
B) duplication
C) correlation
D) sharing

Accepted Answer

The process of copying directory data to multiple domain controllers is known as replication. Replication helps to ensure consistency of data across all domain controllers in the network. Duplicate refers to an exact copy of something, and correlation is a statistical measure of the relationship between two variables. Sharing refers to the act of allowing others to access or use something that belongs to you.
