Difference between Open Source Software and Closed Source Software (2024)

Overview

Test Series

When it comes to software, there are mainly two types that are differentiated based on the accessibility of their source code - Open Source Software (OSS) and Closed Source Software (CSS). Open source software, as the name suggests, is a type of software whose source code is readily available to the public. On the contrary, closed source software keeps its source code under wraps, accessible only to the creator or the authorized organization.

Exploring Open Source Software

Open Source Software, or OSS, is a type of software that allows its source code to be publicly accessible. This means that anyone can view, modify, and use the code. The key advantage of OSS is its affordability and the low restrictions on the modification and usability of the software.

Examples: Linux, Apache, WordPress, Drupal, Audacity, LibreOffice, and many others.

Understanding Closed Source Software

Closed Source Software, or CSS, is the opposite of OSS. It keeps its source code confidential, with access granted only to the creator or the authorized organization. The software usually comes with a license, and users are required to purchase the software to use it. This leads to higher costs and restrictions on the modification and usability of the software.

Examples: Windows OS, Adobe Photoshop, iTunes, Microsoft Office Suite, AutoCAD, and many others.

Dissecting the Differences Between Open Source and Closed Source Software

Let's delve into the nuances that set Open Source Software and Closed Source Software apart.

Parameters	Open Source Software	Closed Source Software
Abbreviation	Commonly known as OSS.	Commonly known as CSS.
Source Code Accessibility	The source code is public and open to all.	The source code is closed and protected from public access.
Modification of Software	The code can be freely modified by any user or organization, thanks to its open-source nature.	Only the creator or the authorized organization can modify the code.
Cost	OSS is usually free or low-cost.	CSS is generally more expensive due to licensing fees.
User Restrictions	Minimal to no restrictions on the modification or usage of the software.	Users are bound by license agreements that restrict software modification and usage.
Programmer Recognition	Programmers often compete for recognition in the open-source community.	Recognition of programmers is usually within the organization.
Programmer Feedback	All programmers can suggest improvements, which are incorporated if approved by the software developers.	Only hired programmers within the organization can suggest improvements.
Team Size	A large OSS project may involve numerous programmers working in teams.	The team size in a CSS project is usually limited.
Code Purchase	The source code is included with the software purchase.	The software can be purchased without the source code.
Installation Requirements	OSS can be installed on any device.	A valid license is required to install CSS on a device.
Error Handling	OSS is known for quick error detection and resolution.	CSS provides robust error handling and prevention mechanisms.
Responsibility	Responsibility for OSS is not assigned to any specific individual or organization.	The vendor is responsible for the CSS.
Examples	Linux, Apache, WordPress, Drupal, Audacity, LibreOffice, etc.	Windows OS, Adobe Photoshop, iTunes, Microsoft Office Suite, AutoCAD, etc.
