e. In computing, a virtual machine (VM) is the virtualization or emulation of a computer system. Virtual machines are based on computer architectures and provide the functionality of a physical computer. Their implementations may involve specialized hardware, software, or a combination of the two. Virtual machines differ and are organized by ...
Virtualization. In computing, virtualization (v12n) is a series of technologies that allows dividing of physical computing resources into a series of virtual machines, operating systems, processes or containers. [1] Virtualization began in the 1960s with IBM CP/CMS. [1] The control program CP provided each user with a simulated stand-alone ...
Containerization (computing) In software engineering, containerization is operating-system–level virtualization or application-level virtualization over multiple network resources so that software applications can run in isolated user spaces called containers in any cloud or non-cloud environment, regardless of type or vendor.

A system virtual machine (also called SYS-VM [citation needed]) is a virtual machine (VM) that provides a complete system platform and supports the execution of a complete operating system (OS). [1] These usually emulate an existing architecture, and are built with the purpose of either providing a platform to run programs where the real ...
e. Elementary school children coding in a robotics programme. Computer science education or computing education is the field of teaching and learning the discipline of computer science, [1][2][3][4][5][6] and computational thinking. [7][8][9] The field of computer science education encompasses a wide range of topics, from basic programming ...
Hypervisor. A hypervisor, also known as a virtual machine monitor (VMM) or virtualizer, is a type of computer software, firmware or hardware that creates and runs virtual machines. A computer on which a hypervisor runs one or more virtual machines is called a host machine, and each virtual machine is called a guest machine.
Temporal isolation among virtual machines. Temporal isolation or performance isolation among virtual machine (VMs) refers to the capability of isolating the temporal behavior (or limiting the temporal interferences) of multiple VMs among each other, despite them running on the same physical host and sharing a set of physical resources such as ...
A VMScluster, originally known as a VAXcluster, is a computer cluster involving a group of computers running the OpenVMS operating system. Whereas tightly coupled multiprocessor systems run a single copy of the operating system, a VMScluster is loosely coupled: each machine runs its own copy of OpenVMS, but the disk storage, lock manager, and security domain are all cluster-wide, providing a ...
