Exokernel is an operating system kernel developed by the MIT Parallel and Distributed Operating Systems group, [1] and also a class of similar operating systems. Operating systems generally present hardware resources to applications through high-level abstractions such as (virtual) file systems.

However, the OpenTag RTOS employs an exokernel architecture (as of version 0.4), so a monolithic kernel is not required. Applications developed for OpenTag may safely reference the library or directly access the hardware, as befits the exokernel design model.
A monolithic kernel is an operating system architecture with the entire operating system running in kernel space. The monolithic model differs from other architectures such as the microkernel [ 1 ] [ 2 ] in that it alone defines a high-level virtual interface over computer hardware .
The Windows NT operating system family's architecture consists of two layers (user mode and kernel mode), with many different modules within both of these layers.One prominent example of a hybrid kernel is the Microsoft Windows NT kernel that powers all operating systems in the Windows NT family, up to and including Windows 11 and Windows Server 2022, and powers Windows Phone 8, Windows Phone ...
BareMetal is an exokernel-based single address space operating system (OS) created by Return Infinity.. It is written in assembly to achieve high-performance computing with minimal footprint [3] [4] with a "just enough operating system" approach. [5]
Microsoft's new topological architecture was used to develop its Majorana 1 processor, offering what the company called in its press release "a clear path to fit a million qubits on a single chip ...
The unikernel architecture builds on concepts developed by Exokernel and Nemesis in the late 1990s. Design In a library operating system, protection boundaries are ...
