22. Information Technology and Systems Information System: An Information System (IS) is the system of persons, data records and activities that process the data and information in a given organization, including manual processes or automated processes. Mr.Omer Salih Dawood

23. Applications of information systems Information systems deal with the development, use and management of an organization's IT infrastructure. The study of information systems, focuses on why and how technology can be put into best use to serve the information flow within an organization. Mr.Omer Salih Dawood

25. Flow of Control Flow of control: Flow control is the management of data flow between computers or devices or between nodes in a network so that the data can be handled at an efficient pace. Mr.Omer Salih Dawood

26. Batch and Interactive Processing Batch processing: collecting jobs in a single batch and then execute them without further interaction what the user. Interactive processing: Allows a program being executed to carry on a dialogue with the user through remote terminals. Requires real-time processing. Mr.Omer Salih Dawood
