Question 1

When using file servers on local area networks,excessive data movement is one limitation.

Accepted Answer

Excessive data movement can occur when multiple users are accessing and modifying large files on a file server, which can result in slower network speeds and increased network traffic.

Question 2

In the client/server architecture,the client workstation is most often responsible for managing the user interface.

Accepted Answer

In a client/server architecture, the client workstation typically manages the user interface, while the server manages the backend data and processing. Therefore, option A is correct.

Question 3

In a client-based LAN,the file server handles all data manipulations.

Accepted Answer

In a client-based LAN, the file server primarily stores and manages files, while data manipulations are typically performed on the client machines.

Question 4

The database engine is the front-end portion of the client/server database system that provides the user interface and data manipulation functions.

Accepted Answer

The database engine is the back-end portion of the client/server database system that manages the storage, retrieval, and manipulation of data. The front-end portion provides the user interface and data manipulation functions.

Question 5

In a file server environment,the DBMS runs only on the file server.

Accepted Answer

In a file server environment, the DBMS can run on either the file server or on a separate database server. It depends on the specific setup and requirements of the organization.

Question 6

An advantage to using file servers on local area networks is the ability to centralize data control.

Accepted Answer

The answer of An advantage to using file servers on...

Question 7

When designing distributed and Internet systems,you should consider information about the site,processing needs,and data for each location.

Accepted Answer

It is important to consider the characteristics of each site, the processing requirements, and the data that will be stored and accessed at each location when designing distributed and Internet systems. Failure to properly account for these factors can lead to inefficiencies, security vulnerabilities, and other issues.

Question 8

Downsizing is the process of migrating mainframe applications to personal computers,workstations,and networks.

Accepted Answer

The answer of Downsizing is the process of migrating mainframe...

Question 9

File server-based architectures benefit from having a very fast hard disk and cache memory in both clients and the server,enhancing their ability to transfer files to and from the network,RAM,and hard disk.

Accepted Answer

File server-based architectures do benefit from having a fast hard disk and cache memory in both clients and the server. This enhances their ability to transfer files to and from the network, RAM, and hard disk.

Question 10

An advantage to using file servers on local area networks is the ability to use thin clients.

Accepted Answer

The answer of An advantage to using file servers on...

Question 11

The primary characteristic of a client-based LAN is that all data manipulation is performed at the client PC,not at the file server.

Accepted Answer

In a client-based LAN, the client PC is responsible for processing and manipulating data, while the file server primarily stores and manages files.

Question 12

In a typical client/server architecture,all database recovery,security,and access management is localized at the client.

Accepted Answer

In a typical client/server architecture, the database recovery, security, and access management are centralized on the server, not localized on the client. The client may have some security measures, but the bulk of it is managed by the server.

Question 13

In a file server environment,each PC stores a copy of the database.

Accepted Answer

In a file server environment, the database is stored on the server, not on individual PCs. PCs may access and manipulate the database through the server, but they do not store a copy of it.

Question 14

In the client/server architecture,the server executes all requests for data so that only data that match the requested criteria are passed across the network to client stations.

Accepted Answer

In the client/server architecture, the server is responsible for processing data requests and filtering the results to send only the relevant data to client stations. This helps to reduce network traffic and improve performance.

Question 15

Corporate downsizing has lessened the individual manager's span of control.

Accepted Answer

Corporate downsizing often increases a manager's span of control as fewer managers are left to oversee the same or even larger number of employees.

Question 16

In a basic LAN environment,all data manipulation occurs on the file server.

Accepted Answer

In a basic LAN environment, data manipulation can occur on both the file server and individual client computers.

Question 17

In a client-based LAN,the file server acts as a shared data storage device,provides additional resources,supports collaborative applications,and provides access to shared data.

Accepted Answer

In a client-based LAN, the file server serves as a centralized data storage device that multiple clients can access and share. It can also provide additional resources such as printers or backup services, support collaborative applications such as email or chat, and grant access to shared data.

Question 18

Upsizing is the process of linking previous stand-alone computers together to form networks that support workgroup computing.

Accepted Answer

Upsizing is indeed the process of connecting individual computers together to form a network that allows for workgroup computing.

Question 19

When designing distributed and Internet systems,the primary deliverables from this stage are decision tables,structure charts,and throwaway prototypes.

Accepted Answer

While decision tables and structure charts may be used in the design stage, throwaway prototypes are typically developed during the prototyping stage rather than the design stage. Design deliverables may include detailed system specifications, data models, and architectural diagrams, among other items.

Question 20

Private network refers to the cabling,hardware,and software used to connect workstations,computers,and file servers located in a confined geographical area.

Accepted Answer

The answer of Private network refers to the cabling,hardware,and software...
