Therefore, the statement that TPS supports the operational level of management is true.

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.

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.

MIS stands for Management Information System. It is an organized portfolio of formal systems that helps in obtaining, processing, and delivering information to support the business operations and management of an organization. MIS provides managers with the necessary tools and information to make informed decisions and improve the overall efficiency and effectiveness of the organization. It includes various components such as hardware, software, data, procedures, and people to gather, process, store, and distribute information.

The first step in the software development life cycle is problem/opportunity identification. This involves identifying the problem or opportunity that the software is intended to address. It is important to clearly understand the problem or opportunity before proceeding with the development process. Analysis, design, and development and documentation are subsequent steps in the software development life cycle that build upon the initial problem/opportunity identification.

The correct answer is Information. Information technology refers to the use, development, and management of technology to process, store, and transmit information. This includes various components such as computer hardware, software, database management systems, and data communication systems. These components work together to enable the effective handling and utilization of information in various industries and sectors.

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.

RAD stands for Rapid Application Development. This approach to software development emphasizes quick prototyping and iterative development. It aims to deliver high-quality software within a short timeframe by involving users and stakeholders in the development process. RAD focuses on collaboration, flexibility, and adaptability, allowing for rapid changes and updates to the software based on user feedback. This methodology is particularly useful for projects with tight deadlines or evolving requirements.

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.

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."

The cost of information can be valuable because information is often seen as an asset that can provide benefits or advantages. Valuable information can help businesses make better decisions, gain a competitive edge, and increase their profitability. Additionally, individuals may be willing to pay for valuable information that can help them solve problems, gain knowledge, or make informed choices. Therefore, the term "valuable" accurately describes the cost of information in many contexts.

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".

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.

SDLC stands for Software Development Life Cycle. This term refers to the process of developing software, including the planning, design, development, testing, and maintenance stages. It is a systematic approach that ensures the efficient and effective creation of software applications. The other options, System Development Life cycle, Software Design Life Cycle, and System Design Life Cycle, are not the correct answers as they do not encompass the entire process of software development.

DSS stands for Decision Support Systems, which are specifically designed to assist both individual and collective decision making processes. These systems provide analytical tools, models, and databases to help users gather and analyze information, evaluate alternatives, and make informed decisions. DSS can be used by individuals or groups, and they are particularly useful in complex and unstructured decision-making situations where multiple factors need to be considered.

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.

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.
