What does "open source" mean?

Open source is called open source. Open source means that users can modify and learn the source code, but the open source system also has copyright and is protected by law.

In fact, there are two types of users facing the open source system. One is programmers, who are most concerned about the source code and whether it can be redeveloped. Second, ordinary end users, who only care about whether the software function is powerful enough.

The key point of the open source system should be "openness", that is, acceptance, tolerance and development, seeking common ground while reserving differences and mutual benefit.

Extended data:

The most familiar open source software is Android. I believe that smartphone users who use non-Apple will definitely use Android every day. It is also one of the most influential open source software. Without the open source of Android, I believe that there are not so many mobile phone manufacturers and the rise of the mobile Internet today.

If only from the ecological point of view, Apple's ecology is also very open, and now they have also launched an open source Swift. In this respect, the two are actually the same, but the open source and open methods are different.

Linux is undoubtedly the most successful open source software. Whether from its current ecological construction or industry evaluation, including the foundation of cloud computing today, it also depends on the contribution and cornerstone of Linux. Of course, there are OpenStack, Hadoop, Spark and so on. And very successful. These open source projects belong to the underlying technology and are supporting the development of big data and cloud computing today.
