Final answer:
COTS (Commercial off-the-shelf) and open-source projects are different from internal/contract projects in terms of their origin, ownership, and accessibility.
Step-by-step explanation:
COTS (Commercial off-the-shelf) and open-source projects differ from internal/contract projects in terms of their origin, ownership, and accessibility.
COTS projects are developed by external companies and are sold as ready-made products. They are designed to meet the general needs of customers without customization.
On the other hand, open-source projects are developed and maintained by a community of contributors. They are freely available for anyone to use, modify, and distribute.
Internal/contract projects, as the name suggests, are developed internally by organizations or contracted to external developers. They are tailored to specific requirements and often kept confidential.
