Data throughput versus responsiveness is often a trade-off that the scheduler works with. It allocates time for different parts of the system depending on how to make the system efficient. The scheduler handles how the CPU execution resources are used for the entire system. The functionality of the Linux kernel is often described to be: The separation of generic and hardware specific code makes it relatively easy to port code to new devices. Most drivers automatically detects hardware existing in, or plugged into, the system and initializes is respectively. Some drivers are very device specific but most drivers are designed and coded to be as generic as possible and isolates the hardware specific code into small isolated parts. All hardware accesses are managed from within kernel space by a lot of different hardware device drivers. In kernel space execute all the central parts of the system to manage an efficient overall system with excellent throughput, execution performance and responsiveness. This enables for the kernel to run with higher priority and to manage how functionality, resources and permissions are used and distributed over the entire system. The separation between kernel and user space is one of the fundamentals in Linux. Many Linux distributions have been released based upon the Linux kernel. The Linux kernel was initially conceived and created by Finnish computer science student Linus Torvalds in 1991.Linux rapidly accumulated developers and users who adapted code from other free software projects for use with the new operating system.The Linux kernel has received contributions from thousands of programmers. ![]() The Linux kernel is released under the GNU General Public License version 2 (GPLv2) (plus some firmware images with various non-free licenses), and is developed by contributors worldwide. ![]() It is one of the most prominent examples of free and open source software. The Linux kernel is the operating system's kernel used by the Linux family of operating systems.
