Let's talk about Linux. Many people think Linux is an operating system. But actually Linux is not an operating system, rather it is a kernel. The kernel gave a light concept to the post about boot loader, ROM, and kernel. But writing this post seems like posting a detail about the kernel. However, the kernel basically helps to establish relationships between hardware and software.
Developers create applications for the Linux kernel. So if you want to run Linux on your computer, you have to use the application or package written on this kernel. And these packages of Linux are called Distribution or Distro. There is a lot of distro on the Linux kernel. And they are ready for various tasks. This kernel makes your computer hardware suitable for various applications. Linux Distro provides various applications, tools, and desktop environments for each computing field. And these tasks are combined with the Linux kernel, so it has become a full computer operating system.
Now if someone says that he is using Linux on his computer, it means that he is using the Linux kernel and running the application written on the kernel is running on the PC. What is the matter?
