What is Userspace?
A safe area where user applications run without interfering with the computer's kernel.
Overview
Operating systems are divided into two main parts: kernel and userspace. Userspace is where the browser, music player or code editors you use run. An error here will not crash the entire computer, it will only affect that application.
