How Linux Works


Linux is the operating system that powers everything from supercomputers to smartphones and tablets. It is the world’s most popular open source operating system, and many businesses rely on it. It powers the cloud, containers, IoT, edge computing, big data and much more. If you want to be a developer, work in IT or run a business, you need to understand how this massive piece of software works.

In 1991, Linus Torvalds developed the kernel that would become linux. He intended it to be a replacement for the Unix operating system. But it grew into something far bigger than that. Its success has allowed it to spawn an entire ecosystem of software tools, including many widely used programming languages. It has also given rise to other technologies, such as Android phones, virtualization, and open hardware standards.

Because Linux is free and open source, it has a huge community of users. Those users contribute to the operating system’s code, as well as use it for personal and commercial purposes. In the past, some people criticized this model of open source development, but it has proven successful in making a reliable and adaptable operating system.

Linux has a wide variety of user interfaces and features that make it flexible for nearly any use. It can be installed on any hardware and runs on a wide range of processors. It can even be used on embedded devices such as cell phones and tablet computers. The linux operating system also has an expansive ecosystem of software tools that can be downloaded and installed.

Unlike other operating systems, linux is based on a monolithic kernel design. The kernel manages hardware resources and provides low-level services for the rest of the operating system. The kernel has a graphical user interface (GUI) and supports a wide variety of programming languages.

It is also known for its advanced security features, including a comprehensive set of audit tools and a centralized file system. It is also highly stable, which makes it a great choice for mission-critical applications.

Although Linux is often considered a technical operating system, it is very easy to get started with for basic functions such as browsing the Internet and using social media. It can even be used for light gaming. It has an extensive support community and a large number of applications available. Some of these are designed for specific tasks, such as ubuntu for software development and kali linux for ethical hacking and security testing. The foundation that oversees the Linux operating system is a nonprofit. Its funding comes from donations and the contributions of programmers from major tech companies. These programmers help to keep linux stable and secure and improve its functionality. The Linux Foundation reports that in 2017, thirteen per cent of all fixes and improvements to the operating system came from paid contributors. This includes employees of companies such as Google, Intel, and IBM. Other contributors include individuals who write their own software to augment or enhance the Linux ecosystem.
