Disadvantage of writing OS in high level language such as C?
Nothing. Every modern OS is written in C, except for some little special parts (like interrupt-handling) that are written in Assembly.
What is a disadvantage to server virtualization?
A significant disadvantage of server virtualization is the potential for resource contention, where multiple virtual machines compete for the same physical resources, such as CPU and memory. This can lead to performance degradation if not managed properly, especially under heavy workloads. Additionally, the complexity of managing a virtualized environment increases, which may require specialized skills and tools to ensure optimal performance and security.
What is the advantage and disadvantage of Blender software?
1. it's free www.blender.org to download 2. Supports programming in python 3. it can develop games. 4. very fast, lightweight, and no install needed 5. run's on many os's win32, linux, mac osx, etc. = Disadvantage = 1. Learning curve for non standard gui
What is a disadvantage for a screw?
The disadvantage of the screw is you have to put greater distance.
What disadvantage of transistor did the circuit eliminate?
One significant disadvantage of transistors is their susceptibility to thermal instability, which can lead to fluctuations in performance as temperature changes. The circuit design may incorporate feedback mechanisms or temperature compensation techniques to stabilize the transistor's operation, thus mitigating issues like thermal runaway. Additionally, certain circuits may use complementary pairs of transistors to balance performance and improve efficiency, further addressing the inherent limitations of individual transistor components.
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 kernel is Mac OS X based on?
Mac OS X is based on the XNU kernel, a microkernel Mach kernel with a BSD userland, which makes Mac OS X's kernel a hybrid-kernel.
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).
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.
What is the difference between microkernel and nanokernel?
Microkernel I Smaller Than A Nanokernel
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 are the key differences between a monolithic kernel and a microkernel in terms of their architecture and performance?
A monolithic kernel has all operating system services running in the same address space, while a microkernel keeps only essential services in the kernel space and runs other services in user space. This makes microkernels more modular and easier to maintain, but can lead to slightly lower performance due to increased communication overhead between components.
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.
Advantages and disadvantages of spanning tree protocol in networking?
the disadvantage os stp that it is time consuming.
Is Mac OSX is a distribution of Linux?
OS X was forked from the FreeBSD 2.x/3.x branch. with kernel mods and the quartz userland. the various OS X releases have corresponding FreeBSD releases. it uses the FreeBSD mach microkernel with os9 compatibility. Darwin is the development builds of OS X versions. the FreeBSD guys backport OS X tech into their OS. OS X is opensource aside from the quartz userland. OS X also includes kernel components from the NeXT step operating system.
What is Mac OS X Darwin?
Mac OS X Darwin is the open-source core of Apple's macOS operating system, providing the foundational elements such as the kernel, device drivers, and system libraries. It is based on the XNU (X is Not Unix) kernel, which combines components from both BSD Unix and the Mach microkernel. Darwin serves as the underlying architecture for macOS, facilitating compatibility and performance while allowing developers to access its source code for customization and development purposes. It plays a crucial role in the stability and functionality of the macOS environment.
