Insurance involves transferring risk of loss from one entity to another in exchange for payment. There are key concepts like insurers, insured parties, premiums, and agents. The insurance process involves agents describing policies to prospective clients, selecting suitable schemes, paying claims when insured events occur, and redeeming matured policies. Insurance is categorized into life and general types. The IRDA regulates and promotes the orderly growth of the insurance industry in India through powers like registration, adjudication, and specifying business percentages. India's insurance industry has grown significantly and faces some challenges but has strong future growth prospects.
