How do user programs and system services interact in a microkernel?
by message passing
What are the advantages of a microkernel?
The microkernel was designed to address the increasing growth of kernels and the difficulties that came with them. In theory, the microkernel design allows for easier management of code due to its division into user space services. This also allows for increased security and stability resulting from the reduced amount of code running in kernel mode. For example, if a networking service crashed due to buffer overflow, only the networking service's memory would be corrupted, leaving the rest of the system still functional.
List and briefly explain seven potential advantages of a microkernel design compared to a monolithic design?
roubustness scalability security flexibility extensibility portability interactivity
What is prex OS?
Prex OS is an open source portable real-time operating system for embedded systems. Prex is designed specifically for tiny, resource-constrained platforms. It is written in ANSI C based on traditional microkernel architecture. Prex is royalty-free software released under BSD License.

Why you dont use a microkernel in Linux?
Because the communication between different parts of the system is more complex in a microkernel.
What microkernel does the Hurd currently run on?
mach
What is the Architecture of microkernel for solaris?
None. Solaris has a monolithic kernel.
What are the windows version in mickrokernal?
No version of Windows currently uses a microkernel
How do user programs and system services interact in a microkernel?

How do user programs and system services interact in a microkernel architecture?
by message passing
What are the main advantages of the microkernel approach?
The main advantages are that new services do not need to modify the kernel and it's easier to port between hardware. Also, microkernels provide more security because of less time in privileged mode.
What are the disadvantages of a microkernel?
suffer from performance decreases due to increased system function overhead. Consider the history of Windows NT. The first release had a layered microkernel organization. However, this version delivered low performance compared with that of Windows 95. Windows NT 4.0 partially redressed the performance problem by moving layers from user space to kernel space and integrating them more closely. By the time Windows XP was designed, its architecture was more monolithic than microkernel.

How is Linux is converted into RTLinux?
It isn't. RTLinux is a separate microkernel that runs Linux as a process. The Linux kernel is essentially unmodified.
What is microkernal?
In computer science, a microkernel is the near-minimum amount of software that can provide the mechanisms needed to implement an operating system (OS).
