A modern computer operating system usually segregates virtual memory into kernel space and user space. Kernel space is strictly reserved for running a privileged operating system kernel , kernel extensions, and most device drivers. In contrast, user space is the memory area where application software and some drivers execute. The term userland or user space refers to all code that runs outside the operating system's kernel. Each user space process normally runs in its own virtual memory space, and, unless explicitly allowed, cannot access the memory of other processes. This is the basis for memory protection in today's mainstream operating systems, and a building block for privilege separation.
A processor in a computer running Windows has two different modes: user mode and kernel mode. The processor switches between the two modes depending on what type of code is running on the processor. Applications run in user mode, and core operating system components run in kernel mode. While many drivers run in kernel mode, some drivers may run in user mode. When you start a user-mode application, Windows creates a process for the application. The process provides the application with a private virtual address space and a private handle table. Because an application's virtual address space is private, one application cannot alter data that belongs to another application.
