What else can I help you with?
A single task such as the task of printing a file that process request from the kernel?
Thread
Witch ranks higher a kernel or a general?
A General.
Why Disable all interrupts was allowed in kernel mode?
It usually doesn't. You may think of one of the followings: 1. When processing a higher priority interrupt, more interrupts with lower priority are not allowed. 2. During the context-switch (user-mode<->kernel-mode, entering/exiting interrupt/exception handler), interrupts may be disabled. 3. When in a critical operation (eg. manipulating shared data), interrupts may have to be disabled (for a very short time-interval).
What is the Linux kernel?
The Linux kernel is the central component of the GNU/Linux operating system. The kernel is the lowest level of interaction between the hardware and the operating system. Individual applications are at a higher level. The kernel along with supporting applications make up the operating system.
What are different types of kernel?
Basically, there are three types of kernel: - Monolithic Kernel- Micro Kernel- ExoKernel Monolithic:As the name itself suggests, the kernel has every services like, FS Management, MM, Process Management, etc. in the kernel space. It does not run as a separate process. So, as you guess, there is no context switching, when you ask for a service. But, the probability of a monolithic kernel getting struck is more. Because, if there is a bug in the kernel itself, nothing can rescue it. Linux and Windows are good examples of Monolithic kernel. Linux, being a monolithic kernel, you can insert modules into the kernel dynamically using insmod command. Micro Kernel:Micro kernel runs all the services as a daemon in the user space. So, if a problem occurs in any of the service, the kernel will be able to decide what to do next. But, you pay-off the time to switch to a service in this type of kernel. Micro kernels are some what difficult to design and build than the monolithic kernel. There are always a discussion over the internet, talking about the advantage and disadvantages of monolithic and micro kernel. Exo Kernel:Exo kernel is not yet stabilized. It's under design and research. The user mode processes running in this type of kernel has the ability to access kernel resources like process tables, etc directly.
How do you implement svm algorithm in java?
A kernel is used to implement the SVM algorithm in practise. An input data space is transformed into the appropriate form using a kernel. The kernel trick is a technique used by SVM. The kernel transforms a low-dimensional input space into a higher-dimensional space in this case. To learn more about data science please visit- Learnbay.co
What is the difference between Hard and Soft real-time systems?
A hard real-time system guarantees that critical tasks complete on time. This goal requires that all delays in the system be bounded from the retrieval of the stored data to the time that it takes the operating system to finish any request made of it. A soft real time system where a critical real-time task gets priority over other tasks and retains that priority until it completes. As in hard real time systems kernel delays need to be bounded
What is Linux virtual kernel for?
The virtual kernel is a kernel that can be used in unbuntu guest. It is a very lean kernel, this helps in reducing overhead. It installs the server kernel via a new name.
What is the core of an operating system?
The Kernel
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 type of kernel does Ubuntu use?
Ubuntu uses the Linux kernel, which is a monolithic kernel with loadable modules.
