Who developed Linux kernel?

The Linux kernel was developed by Linus Torvalds. He started the development as a project while he was a student at the University of Helsinki in Finland. He wanted to create a free and open-source Unix-like operating system, and thus, Linux was born. Here are the steps of its development:

1. In 1991, Linus Torvalds started to work on a non-commercial replacement for MINIX, which was a Unix operating system.

2. On August 25, 1991, Torvalds announced this system in a Usenet posting to the newsgroup "comp.os.minix."

3. He wrote the program specifically for the hardware he was using and independent of an operating system because he wanted to use the functions of his new PC with an 80386 processor.

4. Debugging was done via code reviews in Usenet discussions. The first version of the Linux kernel (0.01) was released on September 17, 1991.

5. After that, many programmers around the world started contributing code to the Linux kernel. It became a collaborative project of multiple developers worldwide.

6. Today, the Linux kernel is used by millions of individuals and companies, as it's the core of various operating systems, most notably Android and all Linux distributions.

The Linux kernel was developed by Linus Torvalds. He started the development as a project while he was a student at the University of Helsinki, Finland. He announced the project in 1991 and released the first version of the Linux kernel, version 0.01, later that year. The kernel was initially designed for personal computers but has since been ported to more hardware platforms than any other operating system.
