Question 1

The collection of computing systems used by an organization is called Information Technology IT) or an Information System IS).

Accepted Answer

The collection of computing systems used by an organization is called Information Technology (IT) or an Information System (IS).

Question 2

When transactions are typically processed as each transaction occurs, it is called "instantaneous processing".

Accepted Answer

When transactions are processed as each occurs, it is called "real-time processing" or "online processing," not "instantaneous processing."

Question 3

According to your text, an Information System IS) is part of an organizational culture that consists of the IS, company policies, and legal regulations.

Accepted Answer

An Information System (IS) is a component of organizational culture, but it is not accurate to say it consists of the IS, company policies, and legal regulations. Instead, an IS supports organizational culture and may interact with company policies and legal regulations, but these elements are distinct from the IS itself.

Question 4

When transactions are typically processed as each transaction occurs, it is called "real-time processing".

Accepted Answer

Real-time processing means processing transactions as they occur in real-time or near real-time.

Question 5

A Management Information System MIS) is a general purpose IS designed to provide reports to managers for tracking operations, monitoring and control.

Accepted Answer

This statement is true as it describes the main purpose of a Management Information System (MIS).

Question 6

Organizations strive to maintain high data quality by validating data - detecting and eliminating obvious errors and omissions, because the more efficiently and thoroughly an organization gathers, stores, processes, retrieves and uses its data, the more productive it is.

Accepted Answer

Maintaining high data quality is important for organizations and one of the ways to achieve it is by validating data, which involves detecting and eliminating errors and omissions. Efficient and thorough management of data can lead to increased productivity for the organization.

Question 7

When transactions are typically processed all together for a defined time window
e.g. end of a day, shift or other time period), it is called "cluster processing".

Accepted Answer

The correct term for processing transactions together for a defined time window is "batch processing," not "cluster processing."

Question 8

A Decision Support System DSS) is an interactive application that aids managers in making decisions that would otherwise require a great deal of time to figure out.

Accepted Answer

A DSS is designed to assist managers in making decisions by providing them with relevant information and analysis tools to support their decision-making process. It is interactive, meaning that the user can modify input data and assumptions, and see how the output changes in response. A DSS is useful when the decision is complex, involves a large amount of data, or requires a lot of computations.

Question 9

Data from sales orders, payroll, accounting, financial, marketing, purchasing, inventory control, and so forth are processed by a combination of hardware and software called Financial Processing Systems FPS).

Accepted Answer

These types of data are processed by Enterprise Resource Planning (ERP) systems, which integrate various functional areas of an organization, not just financial processing. FPS primarily focuses on financial transactions.

Question 10

The critical difference between a DSS and an MIS is that a DSS is often Web-based, whereas an MIS is restricted to company computers for security reasons.

Accepted Answer

The critical difference between a DSS (Decision Support System) and an MIS (Management Information System) is not about their web-based or computer-restricted nature. DSS is a computer-based information system that combines data, analytical tools, and models to support semi-structured and unstructured decision-making tasks. Meanwhile, an MIS is a computer-based system that provides managers with tools to organize, evaluate, and manage information to support decision-making processes within an organization. Both DSS and MIS may be web-based or computer-restricted depending on the organization's security policies and other requirements.

Question 11

The critical difference between a DSS and an MIS is that a DSS is only a software app, whereas an MIS consists of both hardware and software.

Accepted Answer

The critical difference between a DSS and an MIS is not that a DSS is only a software app and an MIS consists of both hardware and software. Both DSS and MIS can be software-only or hardware-software combination systems. The main difference is their purpose and functionality. A DSS is designed to support decision-making processes, while MIS is used for managing and organizing data to support business operations.

Question 12

Data from sales orders, payroll, accounting, financial, marketing, purchasing, inventory control, and so forth are processed by a combination of hardware and software called Transaction Processing Systems TPS).

Accepted Answer

The statement is true. Transaction Processing Systems (TPS) are used to process data from various transactions such as sales orders, payroll, accounting, financial, marketing, etc.

Question 13

The functional difference between a DSS and an MIS is that a DSS contains models that use information to make decisions while an MIS is used to create reports from data.

Accepted Answer

A DSS (Decision Support System) is designed to analyze data and provide recommendations or decision options based on the information. It uses models and algorithms to generate predictions and simulate scenarios. An MIS (Management Information System) is focused on collecting, storing, and retrieving data, and presenting it in a structured and organized way through reports and dashboards. Although both systems deal with data and support decision-making processes, they differ in their main functionalities.

Question 14

A Decision Support System DSS) is a general purpose IS designed to provide reports to managers for tracking operations, monitoring and control.

Accepted Answer

A Decision Support System (DSS) is specifically designed to assist in making decisions, analyzing complex data, and solving problems, rather than just providing reports for tracking operations, monitoring, and control.

Question 15

According to your text, an Information System IS) is part of an organizational culture that consists of the IS, market demands, technology.

Accepted Answer

An Information System (IS) is indeed a crucial part of an organization, but it primarily consists of components such as hardware, software, data, procedures, and people, rather than being described as part of an organizational culture that includes market demands and technology. Organizational culture influences how these systems are used and developed, but it is not a component of the IS itself.

Question 16

According to your text, an Information System IS) is part of an organizational culture that consists of the IS, business processes, and people.

Accepted Answer

The text states that an Information System (IS) is part of an overall organizational culture that includes not only the technology, but also the business processes and people who use and interact with the system.

Question 17

Because data in databases are constantly in use or undergoing changes, data must be extracted, transformed and loaded into a data warehouse prior to use in complex decision making or problem solving tasks.

Accepted Answer

Data from databases need to go through the ETL process before being used in a data warehouse for complex decision making or problem-solving tasks.

Question 18

The central feature of a DSS is a model or formula that enables sensitivity analysis, what-if analysis, goal seeking and/or risk analysis.

Accepted Answer

The central feature of a Decision Support System (DSS) is a model or formula that enables sensitivity analysis, what-if analysis, goal seeking, and/or risk analysis.

Question 19

Given the huge number of transactions, the data in databases are constantly in use and/or undergoing change. This characteristic of databases, referred to as variability.

Accepted Answer

Databases are designed to store and manage data that is subject to change and frequent usage, making variability a characteristic of databases.

Question 20

When transactions are typically processed all together for a defined time window
e.g. end of a day, shift or other time period), it is called "batch processing".

Accepted Answer

Batch processing is a technique of processing large volumes of data in batches at a defined time interval or end of a specific period. It is commonly used in industries such as finance, banking, and payroll processing.
