Closed-sourced, also known as proprietary software, refers to computer software whose source code is not made publicly available. The developers of closed-sourced software retain exclusive control over the software's intellectual property and restrict access to its source code, licensing it to users under specific terms and conditions. This contrasts with open-source software, where the source code is freely available for modification and distribution. Closed-sourced software typically requires a license for its use, and modifications or redistribution are often prohibited.
Close-sourced meaning with examples
- Many businesses rely on **closed-sourced** CRM systems like Salesforce for managing customer relationships. The software's source code is a closely guarded secret, ensuring data security. While effective, this means customizing the system requires purchasing the developer's services. The proprietary nature also limits integration with third-party applications unless specific APIs are provided.
- A common example of **closed-sourced** operating system would be Microsoft Windows. Its source code is not available for public inspection or modification. Users access features and functionalities as defined by Microsoft. The software's development is entirely under the control of Microsoft, with users granted license but unable to alter the core code directly.
- The popular video game, *Call of Duty*, is a prime instance of a **closed-sourced** game. Its source code is tightly controlled by Activision. Players can enjoy the game and utilize it with their purchased license, but modding or altering the fundamental game code is prohibited, preventing players from building their versions.
- Adobe Photoshop, widely used for image editing, is a **closed-sourced** application. Its source code is proprietary, preventing independent developers from modifying or distributing their version of it. While Adobe offers its service with features, users can not have the ability to change anything without permission. The advantage is stability.
- Many embedded systems within automobiles utilize **closed-sourced** software. The software controlling critical functions like the engine control unit is often kept as proprietary, protecting the car's proprietary technology. This limits access for diagnostics and modifications to the system's manufacturers or authorized service providers.
