What the difference between Unix and Linux
Unix and Linux are two operating systems that share many similarities, but there are also some key differences between them.
Unix is an older operating system that was first developed in the 1960s and 1970s. It was designed to be a portable, multi-user, and multitasking operating system that could run on a variety of computer hardware. Unix is a proprietary operating system, which means that it is owned and controlled by a single company (originally AT&T, now owned by The Open Group).
Linux, on the other hand, is a newer operating system that was first developed in the early 1990s. It was based on the Unix operating system, but it was developed as an open-source operating system, which means that it is free and anyone can contribute to its development. Linux is also designed to be a portable, multi-user, and multitasking operating system, and it can run on a wide variety of computer hardware.
One of the main differences between Unix and Linux is that Unix is a proprietary operating system, while Linux is an open-source operating system. This means that Unix is developed and owned by a single company, while Linux is developed by a community of developers who contribute code and make decisions about the direction of the operating system.
Another difference between Unix and Linux is that Unix tends to be used more in commercial settings, while Linux is often used in academic and research environments, as well as in servers and embedded systems. Unix is also typically more expensive than Linux, due to its proprietary nature.
Overall, while Unix and Linux share many similarities in terms of their design and functionality, there are some key differences between them that may make one more appropriate than the other depending on the specific needs of a particular user or organization.
Three common Operating System
There are many different operating systems available today, but some of the most commonly used ones include:
- Microsoft Windows: This is a proprietary operating system developed by Microsoft Corporation. It is the most widely used operating system for personal computers and is known for its user-friendly interface, support for a wide range of hardware and software, and compatibility with a large number of applications.
- macOS: This is a proprietary operating system developed by Apple Inc. It is used exclusively on Apple’s Macintosh computers and is known for its sleek design, integration with Apple’s hardware and software ecosystem, and support for creative applications such as video and music editing.
- Linux: This is an open-source operating system that is freely available and can be modified by anyone. It is known for its flexibility, security, and stability, and is widely used in servers, supercomputers, and other specialized applications. There are many different versions or “distributions” of Linux, each with its own unique features and applications. Some of the most popular Linux distributions include Ubuntu, Debian, and Fedora.
