IS full form is Information System. An IS refers to the method of collecting, transforming, organising, archiving, and analysing information. It comprises four components, which are functions or structure, tasks, technology, and people. Information Systems are available in various sizes and shapes to meet the needs of an organisation. The goal of each IS is to facilitate operations, decision-making, and management. These are often developed to assist human beings in carrying out tasks for which they are insufficiently prepared. Such tasks or activities include complex calculations, data handling, concurrent processing, etc.
