IT Concepts And Management True/False Quiz

The statement is true because information systems can indeed be organized according to the organizational hierarchy or by the nature of the supported task. Organizing information systems based on the organizational hierarchy involves categorizing them according to different levels within the organization, such as departments or the entire enterprise. On the other hand, organizing them based on the nature of the supported task involves categorizing them according to the specific tasks they support, such as operational tasks that support day-to-day operations, managerial tasks that support decision-making, and strategic tasks that support long-term planning.

Alexander Graham Bell is credited with inventing the telephone. He was a Scottish-born scientist, inventor, and teacher of the deaf. In 1876, Bell was awarded the patent for the telephone, which revolutionized communication by allowing people to speak to each other over long distances. His invention laid the foundation for the development of modern telecommunications and had a profound impact on society, transforming the way people connect and communicate with each other.

The statement is true because managerial activities, decisions, and the information systems that support them can indeed be classified into three categories: operational, tactical, and strategic. Operational activities and systems are focused on day-to-day tasks and short-term goals, tactical activities and systems are focused on medium-term planning and resource allocation, and strategic activities and systems are focused on long-term planning and overall organizational objectives. This classification helps managers to effectively allocate resources, make decisions, and achieve organizational goals at different levels of the organization.

Transaction processing systems are critical because they are responsible for handling and recording the day-to-day transactions of a business. These systems ensure that important business operations, such as purchasing materials, billing customers, processing payroll, and shipping, are carried out smoothly and efficiently. Without transaction processing systems, businesses would struggle to manage these essential tasks, leading to potential errors, delays, and inefficiencies in their operations. Therefore, the statement "Transaction processing systems are critical because they support business operations" is true.

Functional area information systems are designed to support the operations and decision-making processes of middle-level managers. These systems gather and summarize data from various sources, such as sales, finance, and human resources, and provide reports that help managers analyze and monitor their department's performance. By providing timely and accurate information, these systems enable managers to make informed decisions and take appropriate actions to achieve their department's goals. Therefore, the statement that functional area information systems provide major support for middle-level managers is true.

Enterprise resource planning (ERP) systems are designed to integrate various functional areas of an organization, such as finance, human resources, supply chain management, and customer relationship management. This integration is achieved through a common database, which allows for seamless sharing of information across different departments. By having a centralized database, ERP systems provide real-time and accurate data to all areas of the organization, enabling better decision-making, improved communication, and increased efficiency. Therefore, the statement that ERP systems tightly integrate functional area information systems via a common database is true.

Information systems are designed to support the operations and processes of organizations. They are built based on the requirements and needs of individuals and groups within the organization. By aligning with the structure of organizations and catering to the needs of its members, information systems can effectively facilitate communication, collaboration, and decision-making within the organization. Therefore, the statement is true.

Clerical workers are supported mainly by office automation systems and functional area information systems. This means that these workers rely on technology and software tools to carry out their tasks efficiently. Office automation systems help with tasks such as word processing, data entry, and file management, while functional area information systems provide support for specific areas of the organization, such as accounting, human resources, or customer service. Therefore, it is true that clerical workers are primarily supported by these systems.

The statement is false because a Transaction Processing System (TPS) does provide input data for other support systems. TPS is designed to capture and process data from business transactions in real-time, and this data can be used as input for other systems such as Management Information Systems (MIS), Decision Support Systems (DSS), or Executive Information Systems (EIS). The data collected in a TPS is often used for reporting, analysis, and decision-making purposes in these support systems. Therefore, the statement is incorrect.

The given statement is false. Point of Sales (POS) systems are not the main IT support systems. While POS systems are important for managing sales transactions and inventory, they are just a part of the overall IT infrastructure in a business. Other IT support systems such as customer relationship management (CRM), enterprise resource planning (ERP), and supply chain management (SCM) systems also play crucial roles in supporting business operations.

The statement is incorrect. M-commerce, which refers to mobile commerce, actually enables users to experience a pervasive computing environment. Through mobile devices, users can access various services, applications, and information anytime and anywhere, contributing to a more pervasive computing experience. Therefore, the correct answer is False.

The statement is false because transaction processing systems do not necessarily integrate the functional area information systems via a common database. While transaction processing systems are designed to process and record transactions, they may not always be integrated with other functional area systems. Integration can vary depending on the organization's specific setup and requirements.

Lower level managers do not make tactical decisions. Tactical decisions are typically made by middle-level managers who are responsible for implementing the strategic decisions made by top-level managers. Lower level managers, on the other hand, focus on day-to-day operations and supervising employees. They are more involved in operational decisions and tasks rather than strategic or tactical decision-making. Therefore, the given statement is false.

Electronic storefronts are not specifically set as trading places for commodities such as stock and shares. While electronic storefronts can be used for buying and selling various goods and services, they are not limited to trading stock and shares. Therefore, the statement is false.

The given statement is false. The intranet refers to a private network that is only accessible to an organization's employees or members. It is used to share information, collaborate, and communicate within the organization. It does not include external networks or databases.
