BlueStacks released BlueStacks 3 in July 2017, featuring a new engine and front-end design. [19] This version introduced App Center for personalized game suggestions, an account system, chat, a new keymapping interface, and multi-instance support. The multi-instance feature permits users to launch multiple BlueStacks windows using the same or ...
An example of a computer with multiple operating systems per storage device is a dual-booting computer that stores both Windows and Linux on the same disk drive but where the BIOS in the system does not let the user boot individual drives and partitions. In this case a multi-booting boot loader is necessary. Also, the disk must be partitioned ...
Software multitenancy is a software architecture in which a single instance of software runs on a server and serves multiple tenants. Systems designed in such manner are "shared" (rather than "dedicated" or "isolated"). A tenant is a group of users who share a common access with specific privileges to the software instance.
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.

Different virtualization techniques are used, based on the desired usage. Native execution is based on direct virtualization of the underlying raw hardware, thus it provides multiple "instances" of the same architecture a real machine is based on, capable of running complete operating systems.
A Dalvik-powered phone. The relative merits of stack machines versus register-based approaches are a subject of ongoing debate. [17]Generally, stack-based machines must use instructions to load data on the stack and manipulate that data, and, thus, require more instructions than register machines to implement the same high-level code, but the instructions in a register machine must encode the ...
The execution of multiple processes over a period of time, rather than simultaneously, is known as concurrent execution. A multiprogramming or multitasking OS is a system that can execute many processes concurrently. Multiprogramming requires that the processor be allocated to each process for a period of time and de-allocated or issued at an ...
PR/SM (Processor Resource/System Manager) is a type-1 Hypervisor (a virtual machine monitor) that allows multiple logical partitions to share physical resources such as CPUs, memory, I/O channels and LAN interfaces; the LPARs can share I/O devices such as direct access storage devices (DASD). Initially, the operator could select either basic ...
