The user mode is capable of sending IO requests to the relevant kernel mode device drivers by using the IO manager. However, the programs running in the kernel model has no restrictions to access system memory, hardware, and resources. The programs running in the user mode has limited access to system resources. These services operate in the kernel mode.įurthermore, the windows system can operate in two modes: the user mode and kernel mode. Windows architecture consists of windows kernel, hardware abstraction layer (HAL), drivers and other supporting services. It is capable of working with both uniprocessor and symmetrical multiprocessor-based computers, and therefore, referred to as hybrid kernel as well. This kernel is called the Windows NT kernel. The devices with the Microsoft Windows operating system consist of the windows kernel. – Comparison of Key Differences Key Terms What is the Difference Between Windows Kernel and Linux Kernel Moreover, devices in Windows and Linux have different kernels. Various operating systems have different kernels depending on the type of OS. It performs functionalities such as communicating with hardware devices, process management, file handling, and many other tasks. The kernel is the core of the operating system. The main difference between Windows Kernel and Linux Kernel is that Windows kernel, which is in Windows Operating System, is a commercial software while Linux Kernel, which is in the Linux Operating System, is an open source software.
