Question 1

Security is especially important when data or processing is performed at a centralized facility,rather than at remote locations.

Accepted Answer

False

Question 2

Compared to mainframe architecture,distributed systems decrease concerns about data security and integrity because fewer individual clients require access to perform processing.

Accepted Answer

Distributed systems actually increase concerns about data security and integrity because there are more individual clients accessing and processing the data, making it more vulnerable to security breaches and data corruption.

Question 3

Even if a user's Internet connection becomes unavailable,the user will still be able to access certain cloud-based services.

Accepted Answer

False

Question 4

A thin client design locates all or most of the application processing logic at the client.

Accepted Answer

A thin client design places most of the application processing logic on the server rather than the client. The client typically only handles user input and display output.

Question 5

The advantage of the application logic layer is that a three-tier design enhances overall performance by reducing the data server's workload.

Accepted Answer

By separating the application logic layer from the data layer, the workload of the data server is reduced, which can enhance overall performance. This is because the application logic layer can handle tasks such as data validation and processing, leaving the data server to focus on retrieving and storing data.

Question 6

In a typical client/server system,the server handles the entire user interface,including data entry,data query,and screen presentation logic.

Accepted Answer

In a typical client/server system, the server mainly handles data storage and processing, while the client handles the user interface and screen presentation logic. The client sends requests to the server and receives responses, but is responsible for the presentation layer.

Question 7

As the size of a business changes,it is easier to alter the capability of a large-scale central server than it is to adjust the number of clients and the processing functions they perform.

Accepted Answer

As the size of a business changes, it is easier to adjust the number of clients and the processing functions they perform than to alter the capability of a large-scale central server. This is because adding or removing clients and adjusting their processing functions is a more flexible solution that can be done more quickly and easily than upgrading or downgrading a central server.

Question 8

A three-tier design includes a middle layer between the client and server that processes the client requests and translates them into data access commands that can be understood and carried out by the server.

Accepted Answer

This statement is true. The middle layer in a three-tier design is often referred to as the application tier or the business logic tier, and it is responsible for processing client requests, performing necessary calculations or validations, and translating them into data access commands that can be executed by the server.

Question 9

A server is a computer that supplies data,processing services,or other support to one or more computers,called clients.

Accepted Answer

This is the correct definition of a server.

Question 10

A main advantage of ERP is that it describes a specific hardware and software environment,also called a platform,which ensures connectivity and easy integration of future systems,including in-house software and commercial packages.

Accepted Answer

ERP's platform provides a standardized environment for connectivity and integration of future systems.

Question 11

Web 2.0 is a reference to a more technically advanced version of the current web.

Accepted Answer

The answer of Web 2.0 is a reference to a...

Question 12

Client/server architecture does involve performance issues that relate to the separation of server-based data and networked clients that must access the data.

Accepted Answer

Client/server architecture can introduce performance issues, such as increased network traffic and the need for efficient data retrieval and communication between the client and server.

Question 13

In contrast to a centralized system,a client/server design separates applications and data.

Accepted Answer

In a client/server design, applications and data are separated between the clients (who request services) and the servers (who provide services). This decentralization is in contrast to a centralized system where all applications and data are located in a single location or server.

Question 14

In a closed design,the remote user's keystrokes are transmitted from his or her terminal to the mainframe,which responds by sending screen output back to the user's screen.

Accepted Answer

The answer of In a closed design,the remote user's keystrokes...

Question 15

Middleware can be seen as representing the slash in the term client/server.

Accepted Answer

This statement is true. Middleware acts as the communication bridge between the client and server, representing the slash (/) in the term client/server.

Question 16

The cloud computing concept envisions a cloud of remote computers that provide a total online software and data environment that is hosted by third parties.

Accepted Answer

The statement is true. The concept of cloud computing involves a network of remote servers that provide online software and data storage, among other services, which are managed by third-party providers.

Question 17

In a bus network,a single communication path connects the central server,departmental servers,workstations,and peripheral devices.

Accepted Answer

In a bus network, all devices are connected to a single communication path, known as the bus. This includes the central server, departmental servers, workstations, and peripheral devices.

Question 18

A web-based application encounters all of the connectivity and compatibility problems that typically arise when different hardware environments are involved.

Accepted Answer

The answer of A web-based application encounters all of the...

Question 19

A router is a device that connects network segments,determines the most efficient data path,and guides the flow of data.

Accepted Answer

This statement is true. A router is a networking device that connects multiple networks or network segments, determines the best path for data transmission, and manages the flow of data between them.

Question 20

Batch processing means that data is managed in groups or batches.

Accepted Answer

Batch processing is a technique of managing data in groups or batches, hence the statement is true.
