user space

(redirected from Userspace)

user space

(1) The memory allocated to applications in a computer that uses an operating system like Linux. Such operating systems keep their kernel in one area of memory (kernel space) with user applications in another. The system prevents the user's applications in user space from accessing any instructions in kernel space.

Programs in user space are typically swapped to and from disk when other programs take precedent (see virtual memory); however, all or most of the kernel resides in physical memory at all times.

(2) A designated part of a website that is set up for users to download files or contribute material.
