Proprietary Software

Proprietary software refers to a type of software for which exclusive rights of modification in the source code remain with the owner. This means that the owner has complete control over the software and can decide who can modify, distribute, or use it. The source code, which is the human-readable form of the software, is typically not made available to the public or the end-users.

Key Features of Proprietary Software:
1. Exclusive Rights: The owner of proprietary software holds exclusive rights to modify, distribute, and use the software. They have full control over its development, licensing, and distribution.

2. Closed Source: Proprietary software is usually closed source, meaning the source code is not available for public viewing or modification. Only the compiled version of the software is distributed, which limits the users' ability to customize or modify it.

3. Limited Redistribution: The owner of proprietary software can restrict or regulate the redistribution of the software. This means that users typically need to obtain a license or permission from the owner to distribute or share the software with others.

4. Commercial Nature: Proprietary software is often developed and sold by companies for profit. The owner may charge a fee for the software, and additional licenses may be required for multiple users or installations.

5. Support and Updates: Proprietary software is typically accompanied by support and maintenance services provided by the owner or the company selling the software. This ensures that users can receive assistance and updates when needed.

Examples of Proprietary Software:
1. Microsoft Windows: The Windows operating system is a proprietary software owned by Microsoft. Users need to purchase a license to use the software and abide by the terms and conditions set by Microsoft.

2. Adobe Photoshop: Photoshop is a popular image editing software developed by Adobe. It is proprietary software that requires a license for use and restricts unauthorized modification or redistribution.

3. Oracle Database: Oracle Database is a relational database management system developed by Oracle Corporation. It is a proprietary software that requires licensing for use and offers various editions with different features.

4. AutoCAD: AutoCAD is a computer-aided design (CAD) software used in architecture, engineering, and construction industries. It is proprietary software developed and sold by Autodesk Inc.

In conclusion, proprietary software grants exclusive rights to the owner, who has control over its modification, distribution, and use. It is typically closed source, commercially developed, and may require licenses for use. Examples include Microsoft Windows, Adobe Photoshop, Oracle Database, and AutoCAD.
