A canned program is a prewritten computer software application available for purchase, intended to address common requirements and tasks without needing extensive customization or bespoke development.
Overview of Canned Programs
Definition and Purpose

These programs are developed by software companies and sold to the consumer market. Examples include word processors, spreadsheets, accounting software, and database management systems.
