Answer briefly the following questions
PART II
1. How Expert System is different from other three classes of information systems
2. Discuss components of system
3. Discuss the skills and roles of system analyst
4. Differentiate open vs closed system
1. Expert systems differ from other classes of information systems in that they are designed to mimic human expertise and decision-making. They use knowledge-based rules and algorithms to analyze data and provide solutions or recommendations in complex problem domains.
2. The components of a system typically include hardware, software, data, processes, and people. Hardware refers to the physical devices that make up the system, software includes the programs and applications that run on the hardware, data is the information that is stored and processed, processes are the tasks and actions that are performed, and people are the individuals who use and interact with the system.
3. The skills and roles of a system analyst include analyzing and understanding user requirements, designing and documenting system specifications, coordinating with developers and stakeholders, evaluating and testing system functionality, and providing ongoing support and maintenance. They need strong analytical, communication, problem-solving, and technical skills to effectively perform these tasks.
4. An open system is one that interacts and exchanges information with its environment, allowing for the flow of inputs and outputs. It is adaptable and can integrate with other systems. In contrast, a closed system is self-contained and does not interact with its environment. It operates on predetermined rules and processes and does not have the ability to incorporate external inputs or outputs.
