18 Best Open Source Software You Should Know About

In this modern era, everything is directly or indirectly related to software. Not only our digital devices but the way we commute to work, the food we eat, and almost every aspect of our life is affected by the presence of software.

Hardware is hard to alter and modify. But software is very dynamic. You can run different types of software on the same hardware as long as it is compatible.

Understanding Types of Software

It is essential to understand the categories of software before proceeding any further. Software is broadly divided into two categories. The first one is called proprietary software. In such a type, only the person, team, or organization who created it maintains exclusive control over it and can modify it. For example, Microsoft Office, or say the iOS operating system.

On the other hand, open-source software, like you guessed it, are those where the source code is available openly. This allows others to view that code, copy it, learn from it, alter it, or share it. Open-source software has a great advantage in terms of collaboration and modification from different people and sources. It encourages programmers to access, view, and modify them whenever they like, as long as they let others do the same when they share their work.

Now that you have understood the fundamental difference between open-source and proprietary software, let’s take a look at the best open-source software in 2019.
