In computing, scheduling is the method by which work specified by some means is assigned to resources that complete the work.

The work may be virtual computation elements such as threads, processes or data flows, which are in turn scheduled onto hardware resources such as processors, network links or expansion cards.

Asymmetric multiprocessing (AMP) was the only method for handling multiple CPUs before symmetric multiprocessing (SMP) was available.

It has also been used to provide less expensive options on systems where SMP was available.

Additionally, AMP is used in applications that are dedicated, such as embedded systems, when individual processors can be dedicated to specific tasks at design time.

In an asymmetric multiprocessing system, not all CPUs are treated equally; for example, a system might only allow (either at the hardware or operating system level) one CPU to execute operating system code or might only allow one CPU to perform I/O operations.

Other AMP systems would allow any CPU to execute operating system code and perform I/O operations, so that they were symmetric with regard to processor roles, but attached some or all peripherals to particular CPUs, so that they were asymmetric with regard to peripheral attachment.

Memory management is a form of resource management applied to computer memory.

The essential requirement of memory management is to provide ways to dynamically allocate portions of memory to programs at their request, and free it for reuse when no longer needed.

This is critical to any advanced computer system where more than a single process might be underway at any time.

Component Object Model (COM) is a binary-interface standard for software components introduced by Microsoft in 1993.

It is used to enable inter-process communication and dynamic object creation in a large range of programming languages.

COM is the basis for several other Microsoft technologies and frameworks, including OLE, OLE Automation, Browser Helper Object, ActiveX, COM+, DCOM, the Windows shell, DirectX, UMDF and Windows Runtime.

The essence of COM is a language-neutral way of implementing objects that can be used in environments different from the one in which they were created, even across machine boundaries.

For well-authored components, COM allows reuse of objects with no knowledge of their internal implementation, as it forces component implementers to provide well-defined interfaces that are separated from the implementation.

The different allocation semantics of languages are accommodated by making objects responsible for their own creation and destruction through reference-counting.

Type conversion casting between different interfaces of an object is achieved through the method.

The preferred method of "inheritance" within COM is the creation of sub-objects to which method "calls" are delegated.

A referee or simply ref is the person of authority in a variety of sports who is responsible for presiding over the game from a neutral point of view and making on-the-fly decisions that enforce the rules of the sport, including sportsmanship decisions such as ejection.

The official tasked with this job may be known, in addition to referee, by a variety of other titles as well (often depending on the sport), including umpire, judge, arbiter, arbitrator, linesman, commissaire, timekeeper, touch judge or Technical Official (by the International Olympic Committee).
