Comparison of operating system kernels

A kernel is a component of a computer operating system. A comparison of system kernels can provide insight into the design and architectural choices made by the developers of particular operating systems. The following tables compare general and technical information for a number of widely used and currently available operating system kernels. Please see the individual products' articles for further information. Even 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. See comparison of Linux distributions for a detailed comparison. Linux distributions that have highly modified kernels — for example, real-time computing kernels — should be listed separately. There are also a wide variety of minor BSD operating systems, many of which can be found at comparison of BSD operating systems. The tables specifically do not include subjective viewpoints on the merits of each kernel or operating system. The major contemporary general-purpose kernels are shown in comparison. Only an overview of the technical features is detailed. A comparison of OS support for different binary formats (executables): Physical s: List of Linux-supported computer architectures This table indicates, for each kernel, what operating systems' executable images and device drivers can be run by that kernel. This may be usable on some situations like file system encrypting. This may be usable on some situations like compression file system.

Protecting ML classifiers from adversarial examples is crucial. We propose that the main threat is an attacker perturbing a confidently classified input to produce a confident misclassification. We consider in this paper the attack in which a small number ...

Kernel (operating system)

The kernel is a computer program at the core of a computer's operating system and generally has complete control over everything in the system. It is the portion of the operating system code that is always resident in memory and facilitates interactions between hardware and software components. A full kernel controls all hardware resources (e.g. I/O, memory, cryptography) via device drivers, arbitrates conflicts between processes concerning such resources, and optimizes the utilization of common resources e.

Comparison of open-source operating systems

These tables compare free software / open-source operating systems. Where not all of the versions support a feature, the first version which supports it is listed.

NetWare

NetWare is a discontinued computer network operating system developed by Novell, Inc. It initially used cooperative multitasking to run various services on a personal computer, using the IPX network protocol. The original NetWare product in 1983 supported clients running both CP/M and MS-DOS, ran over a proprietary star network topology and was based on a Novell-built file server using the Motorola 68000 processor.
