the ability of an operating system to run multiple programs?
multitasking
many operating systems support multitasking which enables many computer programs to appear to run simultaneously on one computer. operating systems may run multiple programs through process scheduling – a software mechanism to switch the cpu among processes often so users can interact with each program while it runs. within hardware, modern day multiprocessor computers or computers with multicore processors may run multiple programs.

first introduced in freebsd version 4, jails are a security mechanism and an implementation of operating-system-level virtualization that enables the user to run multiple instances of a guest operating system on top of a freebsd host. it is an enhanced version of the traditional chroot mechanism. a process that runs within such a jail is unable to access the resources outside of it. every jail has its own hostname and ip address. it is possible to run multiple jails at the same time, but the kernel is shared among all of them. hence only software supported by the freebsd kernel can be run within a jail.
