Linux Kernel

The Linux kernel is the core component of the Linux operating system, acting as the essential interface between a computer's hardware and its software processes. Originally developed by Linus Torvalds in 1991 in Finland, it has since evolved into one of the largest collaborative software projects in history, with contributions from thousands of developers worldwide.

Technically, the kernel manages system resources such as CPU time, memory allocation, and peripheral devices through drivers. It operates in a protected memory space called kernel space, ensuring that user applications cannot directly interfere with critical system operations. Its monolithic architecture allows for high performance, while its modular design enables users to load and unload drivers dynamically.

Today, the Linux kernel powers a massive portion of modern technology, including the vast majority of web servers, cloud infrastructure, supercomputers, and every Android smartphone. It is released under the GNU General Public License v2.0, ensuring it remains free to use, modify, and distribute for the global community.
