Q1. Define the term SYSTEM. Requirement analysis and definition is the foundation for any
systems development. It is independent of the approach you take for design. Explain this
statement with example.
Information system
An information system (IS) – or application landscape – is any combination of information technology and peoples activities using that technology to support operations, management, and decision-making. In a very broad sense, the term information system is frequently used to refer to the interaction between people, algorithmic processes, data and technology. In this sense, the term is used to refer not only to the information and communication technology (ICT) an organization uses, but also to the way in which people interact with this technology in support of business processes.
Some make a clear distinction between information systems, and computer systems ICT, and business processes. Information systems are distinct from information technology in that an information system is typically seen as having an ICT component. Information systems are also different from business processes. Information systems help to control the performance of business processes.
