Day 21 – Chapter 3: Open Source vs Proprietary Software
Class 11 Computer Science
Introduction to Software Types (सॉफ़्टवेयर प्रकारों का परिचय)
Software is broadly categorized into two types based on licensing: Open Source Software and Proprietary Software.
सॉफ़्टवेयर को लाइसेंसिंग के आधार पर दो प्रकारों में विभाजित किया जा सकता है: ओपन सोर्स सॉफ़्टवेयर और प्रोपर्टी सॉफ़्टवेयर।
Open Source Software (ओपन सोर्स सॉफ़्टवेयर)
Open source software is software with source code that anyone can inspect, modify, and enhance. It promotes collaboration and transparency.
ओपन सोर्स सॉफ़्टवेयर वह सॉफ़्टवेयर है जिसका सोर्स कोड सभी के लिए उपलब्ध होता है। इसे कोई भी देख, संशोधित, और सुधार कर सकता है।
- Features:
- Free to use
- Customizable
- Community-driven support
- Examples: Linux, LibreOffice, Mozilla Firefox
Proprietary Software (प्रोपर्टी सॉफ़्टवेयर)
Proprietary software is owned by an individual or company. Its source code is not publicly accessible, and users must purchase licenses to use it.
प्रोपर्टी सॉफ़्टवेयर किसी व्यक्ति या कंपनी द्वारा स्वामित्व प्राप्त होता है। इसका सोर्स कोड सार्वजनिक रूप से उपलब्ध नहीं होता।
- Features:
- Paid licenses
- Restricted access to source code
- Professional support
- Examples: Microsoft Windows, Adobe Photoshop, MS Office
Comparison of Open Source and Proprietary Software (ओपन सोर्स और प्रोपर्टी सॉफ़्टवेयर की तुलना)
| Aspect (पहलू) | Open Source (ओपन सोर्स) | Proprietary (प्रोपर्टी) |
|---|---|---|
| Cost | Free or minimal cost | Requires paid license |
| Customization | Highly customizable | Limited customization |
| Support | Community-driven | Professional and company-provided |
| Source Code | Accessible to all | Restricted access |
