The major contemporary general-purpose kernels are shown in comparison. The tables specifically do not include subjective viewpoints on the merits of each kernel or operating system.

There are also a wide variety of minor BSD operating systems, many of which can be found at comparison of BSD operating systems. Linux distributions that have highly modified kernels - for example, real-time computing kernels - should be listed separately. See comparison of Linux distributions for a detailed comparison. Please see the individual products' articles for further information.Įven though there are a large number and variety of available Linux distributions, all of these kernels are grouped under a single entry in these tables, due to the differences among them being of the patch level. The following tables compare general and technical information for a number of widely used and currently available operating system kernels. A comparison of system kernels can provide insight into the design and architectural choices made by the developers of particular operating systems. A kernel is a component of a computer operating system.
