Question 1

Which of the following is NOT a benefit of distributed data processing?
A)increased responsiveness to organizational needs
B)better correspondence to organizational patterns
C)greater user involvement and control
D)enhanced centralization of data definitions

Accepted Answer

Enhanced centralization of data definitions is not a benefit of distributed data processing. Distributed data processing aims to decentralize data processing to avoid a single point of failure and increase responsiveness, user involvement, and better correspondence with organizational patterns. Centralizing data definitions goes against the philosophy of distributed data processing.

Question 2

Which of the following does distributed processing typically not support?
A)applications
B)device controllers
C)data
D)mainframes

Accepted Answer

Distributed processing is designed to work across multiple processors, computers, and devices to share resources and workload. Mainframes are large centralized computers that are not typically included in distributed processing systems.

Question 3

Database applications are always distributed applications.

Accepted Answer

Database applications can be either centralized, running on a single computer, or distributed, running across multiple interconnected computers. Not all database applications are distributed.

Question 4

The three types of requirements for networking resulting from DDP are connectivity,availability,and performance.

Accepted Answer

The three types of requirements for networking resulting from DDP are indeed connectivity, availability, and performance.

Question 5

There has been a decreasing trend toward distributed data processing.

Accepted Answer

There has been an increasing trend towards distributed data processing due to advances in technology such as cloud computing, big data, and the Internet of Things.

Question 6

Centralized data processing typically involves terminals connected to large computers in a central data processing facility.

Accepted Answer

Centralized data processing involves terminals that are connected to a central data processing facility where large computers process the data.

Question 7

In a centralized architecture,the data processing for an application takes place on the user's computing device.

Accepted Answer

In a centralized architecture, the data processing takes place on a central server or computer system, not on the user's computing device.

Question 8

Which of the following is not a function provided by servers in client / server systems?
A)printing services
B)data entry
C)database services
D)gateways

Accepted Answer

Data entry is typically performed by users, not servers in client/server systems. Servers are responsible for providing specific services and resources to clients, such as printing, database access, and gateways for connecting to other networks.

Question 9

Intranets use the same communication protocols and applications as the Internet.

Accepted Answer

Intranets use the same communication protocols and applications as the Internet, such as TCP/IP and HTTP, but they are private networks meant for internal use within an organization. It is possible for an intranet to have additional security measures and restrictions on access compared to the regular internet.

Question 10

A partitioned database is by definition not a replicated database.

Accepted Answer

A partitioned database is split into separate sections or partitions, whereas a replicated database has multiple copies of the same data in different locations for redundancy and high availability. These are two distinct architectural choices and a database cannot be both partitioned and replicated at the same time.

Question 11

Replicated databases involve copying all or part of the database to additional computers.

Accepted Answer

Replicated databases involve creating copies of the existing database and distributing them to additional computers. This allows for increased availability, data consistency, and fault tolerance.

Question 12

Retail point-of-sale systems are an example of horizontal partitioning of data processing.

Accepted Answer

Retail point-of-sale systems are an example of vertical partitioning, where different systems or components are responsible for specific functions (e.g., sales transactions, inventory management) rather than horizontal partitioning, which involves dividing a database into fragments stored on different servers but each fragment containing the same or similar types of data.

Question 13

Big data and the evolution of data processing and communications technologies continue to reshape the balance of centralized and distributed processing within enterprise networks.

Accepted Answer

This statement is true, as big data and advancements in technology are leading to a shift towards more distributed processing within enterprise networks.

Question 14

Like the Internet,intranets are difficult to manage.

Accepted Answer

Intranets are typically easier to manage than the Internet because they are confined to a single organization, allowing for more centralized control and security measures.

Question 15

Accessibility refers to the percentage of time that a particular function or application is available for users.

Accepted Answer

Accessibility refers to the design of products, devices, services, or environments for people with disabilities, ensuring they can use them effectively.

Question 16

A data processing facility may depart in varying degrees from the centralized data processing organization by implementing a DDP strategy.

Accepted Answer

DDP (Distributed Data Processing) strategy implies that data processing is done in a distributed manner rather than being centralized. Therefore, a data processing facility may depart from the centralized data processing organization by implementing a DDP strategy.

Question 17

Which of the following is NOT a feature of an Intranet?
A)uses Internet based standards,such as HTML and SMTP
B)is used to connect both local and remote sites into one network
C)is used to distribute content to the general Internet
D)can be effectively managed

Accepted Answer

An intranet is a private network that is used within an organization to share information, resources, and communication. It differs from the Internet in that it is not publicly accessible. Therefore, distributing content to the general Internet is not a feature of an intranet. The other options are all features of an intranet, as it uses Internet-based standards, connects local and remote sites, and can be effectively managed.

Question 18

The three ways of organizing data for use by an organization are:
A)centralized,replicated,and partitioned
B)centralized,structured,and partitioned
C)structured,replicated,and partitioned
D)centralized,replicated,and structured

Accepted Answer

Centralized, replicated, and partitioned are the three primary ways of organizing data for use by an organization. Centralized data is stored in a single location, replicated data is duplicated across multiple locations for redundancy and accessibility, and partitioned data is divided into segments that can be stored in different locations for efficiency and scalability.

Question 19

Extranets use different protocols and applications than are used in Intranets.

Accepted Answer

Extranets and Intranets often use the same protocols and applications (such as HTTP, FTP, and web browsers) but differ mainly in terms of access control and network reach, with extranets allowing access to external users.

Question 20

Traditionally,data processing has been organized in a distributed model.

Accepted Answer

Traditionally, data processing was organized in a centralized model, with a mainframe computer or server handling all the processing and storage tasks. However, with the advent of cloud computing and distributed computing systems, data processing is becoming more distributed.
