Software is a program or collection of programs that enable hardware to process data.

Database is a collection of related files or tables containing data.

Network is a connecting system (wireline or wireless) that permits different computers to share resources.

Procedures are the set of instructions about how to combine the above components in order to process information and generate the desired output.

People are those individuals who use the hardware and software, interface with it, or use its output.

Types of Information Systems:-

Functional area information systems (FAIS): support particular functional areas (HR, Marketing, Manufacturing) in an organization.
Enterprise resource planning (ERP) systems: tightly integrate the functional area information systems via a common database
Transaction processing systems (TPS): support the monitoring, collection, storage, and processing (real time) of data from the organization’s basic business transactions.
Interorganizational information systems: connect two or more organizations.
Office automation systems (OAS): support the clerical staff, lower and middle managers, and knowledge workers. These people use OASs to development documents, schedule resources, and communicate.
Business intelligence systems (BI): provide computer-based support for complex, non-routine systems, primarily for middle managers and knowledge workers.
Expert Systems: attempt to duplicate the work of human experts by applying reasoning capabilities, knowledge, and expertise within a specific domain.
Dashboards: support all managers by providing rapid access to timely information and direct access to structured information in the form of reports.
