Opensource Technology

You are here


Open source technology

Open source software is software in which the source code used to create the program is freely available for the public to view, edit, and redistribute. Open source technology is defined as the production and development philosophy of allowing end users and developers to not only see the source code of software, but modify it as well. The Linux operating system is a one of the best-known examples of open source software technology.

One issue that has come up repeatedly in open source has to do with the copyrights assigned to the original software and any modifications made to it. As outlined in most open source license agreements, ownership of the software can never transfer to anyone who modifies the software.

Although most open source software is available to download free, license remains with the original creator of the software and does not transfer to anyone regardless of any modifications, improvements, or add-ons made to the open source software. Although free to download, the software is not free in the sense that the end user can do whatever he/she wants to it including selling it.

Open source vs. closed source

Open source software (OSS) is distributed under a licensing agreement which allows computer code to be shared, viewed and modified by other users and organizations. Closed source software can be defined as proprietary software distributed under a licensing agreement to authorized users with private modification, copying, and republishing restrictions. Closed source is actually the sort of arrangement that you would expect from most businesses, protective of their product and keen to maintain control over their brand and the user experience offered to their customers.

Key differences

  1. Cost
  2. Service
  3. Innovations
  4. Usability
  5. Security
