5.
EIS should offer the capability to _____________into the data.
Correct Answer
A. Drill down
Explanation
The correct answer is "Drill down". EIS (Executive Information System) should offer the capability to drill down into the data. This means that users should be able to navigate from summarized or aggregated data to more detailed or specific data. By drilling down, users can explore and analyze data at different levels of granularity, allowing for a deeper understanding of the information and the ability to identify trends, patterns, and insights. Drill up refers to the opposite action, where users can navigate from detailed data to higher-level summaries. Drill diagonal is not a valid term in this context.
6.
AI is short form of
Correct Answer
B. Artificial Intelligence
Explanation
The correct answer is "Artificial Intelligence." AI is the acronym for Artificial Intelligence, which refers to the development of computer systems that can perform tasks that would normally require human intelligence. This field focuses on creating machines that can learn, reason, and problem-solve, ultimately aiming to replicate human-like intelligence in machines.
7.
The basic component(s) of DSS is (are)
Correct Answer
D. All of the Above
Explanation
The correct answer is "All of the Above" because the basic components of a Decision Support System (DSS) include a database, model base, and DSS software program. A database is necessary to store and retrieve data relevant to the decision-making process. The model base consists of mathematical and statistical models used to analyze the data and generate insights. The DSS software program provides the interface and tools for users to interact with the system and make informed decisions based on the data and models available. Therefore, all three components are essential for the functioning of a DSS.
8.
GDSS is the form of
Correct Answer
C. Group Decision Support System
Explanation
A Group Decision Support System (GDSS) is a form of technology that is designed to facilitate and enhance group decision-making processes. It provides a platform for group members to collaborate, share information, and analyze data in order to reach a consensus or make a decision. GDSS typically includes features such as electronic voting, brainstorming tools, and communication channels to support effective group discussions and decision-making. Therefore, the correct answer is Group Decision Support System.
9.
One of the following is the valid record-based data model.
Correct Answer
B. Relational Model
Explanation
The relational model is a valid record-based data model because it organizes data into tables, where each table represents a specific entity and each row represents a record or instance of that entity. The relationships between entities are established through keys, allowing for efficient data retrieval and manipulation. This model is widely used in database management systems and provides a structured and standardized approach to data organization and querying.
10.
LAN Stands for
Correct Answer
C. Local Area Network
Explanation
LAN stands for Local Area Network. It is a computer network that spans a relatively small area, typically within a building or a group of buildings. LANs are commonly used in homes, offices, schools, and other small-scale environments to connect computers and other devices together, allowing them to share resources and communicate with each other. The other options, Legal Area Network and Last Area Network, are not valid terms and do not exist. Therefore, the correct answer is Local Area Network.
11.
TPS supports the operational level of the management.
Correct Answer
A. True
Explanation
TPS, which stands for Transaction Processing System, is a type of information system that supports the operational level of management. It is designed to process and record day-to-day transactions such as sales, purchases, and inventory updates. The data captured by TPS is used by operational managers to monitor and control the ongoing operations of the organization. Therefore, the statement that TPS supports the operational level of management is true.
12.
There is no difference between MIS and DSS.
Correct Answer
B. False
Explanation
The statement "There is no difference between MIS and DSS" is false. MIS (Management Information System) and DSS (Decision Support System) are two different types of information systems used in organizations. MIS focuses on providing information to support managerial decision-making, while DSS is designed to help users make decisions by providing analytical tools and models. MIS typically provides structured and predefined reports, while DSS allows for more ad-hoc and interactive decision-making. Therefore, there are clear distinctions between MIS and DSS in terms of their purpose, functionality, and capabilities.
13.
DBA Stands for:
Correct Answer
D. Database Administrator
Explanation
DBA stands for Database Administrator. A database administrator is responsible for managing and maintaining an organization's database system. They ensure the database is secure, efficient, and reliable. They handle tasks such as database design, implementation, performance monitoring, backup and recovery, and user access management. A DBA plays a crucial role in ensuring the smooth operation of the database system and its availability to users.
14.
A schema describes:
Correct Answer
D. All of the Above
Explanation
A schema describes all of the above options, which include record relationship, data elements, and record and files. A schema is a conceptual framework that defines the structure, organization, and relationships of data in a database system. It provides a blueprint for how data is organized and stored, including the relationships between different records, the attributes or data elements within each record, and the organization of records and files within the database. Therefore, the correct answer is "All of the Above."
15.
In this topology, there is a central controller or hub.
Correct Answer
A. Star
Explanation
In a star topology, all devices are connected to a central controller or hub. This central controller acts as a central point of communication and manages the flow of data between devices. Each device has a dedicated connection to the central controller, which allows for efficient communication and easy troubleshooting. This topology is commonly used in local area networks (LANs) as it provides high reliability and scalability.
16.
Physical or logical arrangement of network is
Correct Answer
C. Topology
Explanation
Topology refers to the physical or logical arrangement of a network. It defines how the devices in a network are connected and the way data flows between them. This includes the layout of cables, devices, and nodes, as well as the paths that data takes to reach its destination. Different types of network topologies include bus, star, ring, mesh, and hybrid. Therefore, the correct answer for this question is "Topology".
17.
Data communication system spanning states, countries, or the whole world is
Correct Answer
C. WAN
Explanation
A Wide Area Network (WAN) is a data communication system that spans across states, countries, or even the entire world. It allows for the exchange of information over long distances, connecting multiple local area networks (LANs) or metropolitan area networks (MANs). This type of network is typically used by large organizations or internet service providers to connect their offices or users across different geographical locations. Therefore, WAN is the correct answer in this case.
