SSLC IT Chapter 10 Notes
Class 10 IT Chapter 10 Software and Freedom Notes
1. Software and Programs
❖ Source Code
- The human-readable form of a program (written in Python, C, Java, etc.).
- Can be easily edited and learned.
- Example: calculator.py (Python program).
❖ Object Code / Executable Code
- The machine-readable form of software (e.g., .exe, .pyc).
- Cannot be easily modified.
- To make changes, you must have the source code.
2. Why Software Freedom Matters
When source code is available:
- Users can verify how a program works and trust it.
- Learners can study and modify the program.
- Programmers can improve it and share updates.
- Collaboration reduces bugs and security risks.
- Software becomes affordable because no company can monopolize it.
3. Editing a Python Program
Goal: To understand how source code can be modified.
Steps:
- Locate Calculator.pyc (object file) and calculator.py (source file) in the Class 10 folder.
- Open calculator.py in a text editor.
- Find the line that sets button colours or name.
- Change the colour or name (e.g., “Tom” ’ → “YourName” ).
- Save the file and run it with Python 3.
- Observe the changes in the interface.
4. Software Publishing
After developing software, you must publish it for others to use.
❖ When publishing:
- Make it easy to download and use.
- Publish the source code if users can modify it.
- Allow improvements and forks (new versions).
- Clearly specify license terms.
❖ Common Publishing Platforms:
- GitHub-https://github.com
- GitLab-https://gitlab.com
- GNU Savannah – https://savannah.gnu.org
- SourceForge – https://sourceforge.net
- Gitea-https://about.gitea.com
5. Software Licenses
A license defines what users are allowed to do with software.
| Rights/License | GNU GPL | Apache/BSD | EULA (Proprietary) |
| Use of any purpose | ✓ | ✓ | ✗ |
| Read source code | ✓ | ✓ | ✗ |
| Copy/Edit | ✓ | ✓ | ✗ |
| Distribute copies | ✓ | ✓ | ✗ |
| Redistribute modified versions | ✓ | Conditional | ✗ |
| Combine with other software | ✗ | ✓ | ✗ |
Types of Licenses:
- Free Software (GPL) → Freedom to use, modify, share; must remain free.
- Open Source (Apache/BSD) → Freedom to modify and use with other software.
- Freeware → Free to use but not editable.
- Testware → Trial version for limited time.
- Proprietary → Paid and restricted (e.g., Windows, iOS).
6. Free vs Open Source vs Proprietry
| Type | Source Code | Rights | Example |
| Free Software | Open | Full freedom, must remiam free | GIMP |
| Open Source | Open | Flexible sharing | Android, Apache |
| Freeware | Closed | Free use, no change | Adobe Reader |
| Propriety | Closed | Paid, restricted | MS Windows |
FLOSS is a free/Libre and Open Source Software, that combines both ideas.
7. Versions and Forks
- Version = Updated release with improvements.
Example: Kazium v21.12.3 → 21st main version, 12th update, 3rd patch. - Fork = Modified copy of an open project (allowed under its license).
Examples:- LibreOffice (The Document Foundation)
- Apache OpenOffice (Apache Software Foundation)
8. Copyleft and GNU Project
- Copyleft: Uses copyright law to ensure freedom – users can share and modify software, but must keep the same freedoms in redistributed versions.
- GNU Proj ect: Started by Richard Stallman (1983).
- Created free software alternatives to commercial ones.
- GNU = “GNU’s Not Unix”
- Free Software Foundation (FSF): Formed in 1985 to support GNU and promote user freedom.
9. GNU + Linux = GNU/Linux
- Kernel = Core part that interacts with hardware (Linux).
- Shell = Interface that interacts with users (GNU Bash).
- The two together form GNU/Linux, the free operating system.
Creator of Linux kernel: Linus Torvalds.
He also created Git, a version-control tool used to manage collaborative software projects.
10. Free Software Development
How open software is developed:
- Developers publish the concept and prototype online.
- Global users test, suggest improvements, and contribute.
- Code versions are tracked and stored systematically.
- If something goes wrong, previous versions can be restored.
Tools used:
- Git (by Linus Torvalds) – for version control.
- Apache Subversion – centralized version management.
Platforms: GitHub, GitLab, GNU Savannah, etc.
11. GNU/Linux Distributions
Different groups modify GNU/Linux to suit specific needs.
Examples:
- Debian GNU/Linux
- Ubuntu (based on Debian)
- Red Hat Linux
- Slackware Linux
- Kite GNU/Linux (used in schools)
12. Cathedral vs Bazaar Model
- Cathedral Model: Centralized, closed development (used by proprietary software like Microsoft).
- Bazaar Model: Open, public collaboration (used in Linux and other open-source projects).
(Idea by Eric Raymond)
13. Android – A Case of FOSS Success
- Android = Open-source OS based on Linux kernel.
- Used in phones, tablets, TVs, etc.
- Allows manufacturers to make low-cost smart devices.
14. Open Hardware
- Open design concept applied to hardware.
- All circuit layouts, chip designs, and drivers are freely shared.
- Example: Arduino microcontrollers (used in robotics, education).
- Encourages innovation and learning.
