Which of the following demonstrates an information system? Tyra is using the computer to create a birthday card for her friend. Ahmad is installing new software to improve the ease of accessing the database. Shania is creating a printed handbook of company policies for new employees. Ian is making updates to the company website to include the latest product information

An information system is a structured arrangement that collects, processes, stores, and disseminates information to support decision-making, coordination, control, analysis, and visualization in an organization. Out of the scenarios given, Ahmad installing new software to improve the ease of accessing the database clearly demonstrates an information system. This is because Ahmad's actions involve the use of technology (software) to enhance the functionality of a database which is an integral part of an information system, focusing on the organization, retrieval, and management of data.

Extra: Information systems are crucial in modern-day organizations as they provide vital data and information that help in the decision-making process. They typically involve five components: hardware, software, data, procedures, and people. Hardware refers to physical technology like computers and servers. Software includes applications that process data. Data represents the raw facts that are processed into meaningful information. Procedures define the methods and processes that govern how hardware, software, and data interact. Lastly, people are the users and managers of the system who interpret the data and make decisions.

1. Tyra creating a birthday card involves using a computer application, which is just one component of an information system - the software. It does not necessarily involve data processing or information management on a scale that is typical of information systems.

2. Shania creating a printed handbook involves content creation and does not involve processing or managing data through technological means; hence, this is not an example of an information system, but rather an information distribution task.

3. Ian making updates to the company website does involve an information system to an extent, as it requires a content management system (a type of information system) to update and manage the website content. However, Ahmad's task more directly represents the conception of an information system aimed at improving access to an organized collection of data (the database).
