Open-source software is a type of software that allows users to access, modify and distribute its source code. It is highly popular among developers because it provides them with the flexibility to customize the software according to their needs.
However, not all operating systems are open-source. In this article, we will explore some of the operating systems that are not open-source.
Windows is one of the most famous operating systems used worldwide. It was developed by Microsoft Corporation and has been around since 1985.
The source code for Windows is not available to the public, making it a closed-source operating system. Although Microsoft allows developers to create applications that run on Windows, they do not allow them access to its source code.
macOS, formerly known as OS X, is an operating system used in Apple’s desktop and laptop computers. It was first released in 2001 and has undergone several updates since then. Like iOS, macOS is also a closed-source operating system.
Solaris is a Unix-based operating system developed by Sun Microsystems (now owned by Oracle Corporation). Although Solaris was initially released as an open-source project under the name OpenSolaris, Oracle discontinued the project in 2010 and made Solaris a closed-source operating system.
AIX (Advanced Interactive eXecutive) is an operating system used in IBM’s servers and workstations. It was first released in 1986 and has undergone several updates since then. Like Solaris, AIX is also a closed-source operating system.
These are some of the popular operating systems that are not open-source. Although closed-source operating systems provide stability and security, they do not offer the same level of flexibility as open-source operating systems. Developers who prefer to customize their software according to their needs may find open-source operating systems more suitable for their requirements.
