What is a macrokernel?
macro-kernel based operating systems like windows and Linux device drivers are part of kernel ..to interact withkernel need not switch to kernel mode...speed is high
Can there be a open kernel that uses windows graphics drivers or why not?
Most Windows drivers are binaries which are not accepted by many Linux distributions, since they are proprietary and the source can not be audited. Graphics manufacturers have limited incentive to develop the feature-rich drivers found in Windows, due to the relatively small market share of desktop Linux.
What small programs stored on the hard drive that tells the computes how to communicate with a specific hardware device?
On Windows, those are usually referred to as "drivers." On Mac OS X, they are referred to as "kexts", or "kernel extensions." On Windows, if they are not already built into the kernel, they are called "modules."
How a device can be added in Linux?
Generally in Linux you can just plug in the device and go, no need to even install drivers because chances are they're already available. Once you plug in a device, a component of Linux called udev catches the messages from the kernel detecting the insertion of the hardware, searches its rules to see what the appropriate response for the device would be, then loads the appropriate kernel module for the device, all within at most a few seconds. It's definitely faster than Windows' response to Plug-and-Play. Sometimes you might plug in a device that doesn't have drivers in the kernel tree, in which case its best to first Google the device to see if there are any drivers you have to get yourself.
Why Linux OS has not required device drivers?
It does. Most drivers are developed in-kernel, not provided separately by third-party vendors.
Functions of kernel?
The kernel is one of the primary nodes of an operating system for a computer. It contains operating system core functions and the device drivers.
What is the purpose of windows vista 64 bit kernel patch protection?
- It prevents third party drivers from modifying the operating system kernel.
How do you check whether a particular device driver is available in windows and Linux and What is the command?
Windows (at least in Vista)The commandDRIVERQUERY /FO LISTshould return a list of drivers in use and their locations.LinuxThe commandlsmodwill return a list of kernel modules currently in use.modprobe -lwill return a (very long) list of all the kernel modules in the system.
What is kernel and shell and what is the difference between these two?
A kernel is the heart of the operating system and acts as a middle ground between hardware and software. Some (if not all) device drivers are kernel-level drivers as kernelmodules. A shell is a command terminal that allows the user to interact with the user.
What is the name of the software program that lets your computer communicate with a hardware device?
The name of the program that lets your computer to communicate with hardware devices is call KERNEL. Kernel communicates between hardware and software of a computer and manages how hardware resources are used to meet software requirements
Where the kernel reside in computer and what is it?
The kernel resides in your OS of the computer. the kernel has one main function that is to act as translator from applications to your CPU, Memory, and various other devices. In the world of Microsoft it's a go between for applications and the device drivers. In Linux, Mac OS, and, any other Unix based OS the kernel directly talks to the hardware with out the need for device drivers. For more info see the related link
What is the name of the windows 7 kernel program?
Windows 7 does not have a kernel.
