COTS Software
COTS (Commercial Off-The-Shelf) software refers to pre-packaged software applications or systems that are commercially available and ready for purchase or licensing from software vendors. These software products are designed to meet the needs of a wide range of users or organizations without the need for extensive customization or development. COTS software is typically developed and maintained by third-party software companies and is sold to customers under various licensing models, such as perpetual licenses, subscription-based licenses, or usage-based licenses.
