In 1991, Linus Torvalds created the kernel for the Linux operating system, which is free and open-source. Taking inspiration from UNIX and MINIX, Torvalds set out to create a free and adaptable system for desktop computers. The original version of the Linux kernel promoted development teamwork, which drew developers and fans from all over the world. Fully functional operating systems, sometimes called Linux distributions, were produced by integrating several open-source software packages with the Linux kernel. Linux has solidified its position as an integral part of contemporary computing, serving as the operating system for a wide range of devices from servers and PCs to smartphones. Developers, companies, and schools often choose it because of its adaptability, longevity, and robust community support.
Linux, should we?
For direct control of a computer’s hardware and resources including memory, storage, and central processing unit (CPU), Linux is the most famous and widely used open source OS. Between programs and hardware, Linux acts as an OS. By doing so, it links your programs to the computational resources available in your hardware. Supercomputers, smart devices, and internet infrastructure hardware all use Linux as their operating system. Android, Google’s operating system, is the most famous of these.
