Microsoft Certifications are professional certifications verifying demonstrated proficiency with Microsoft products.

They exist in the categories of Server, Desktop, Applications, Database, and Developer with a variety of tiers of proficiency certified, including Solutions Associate (MCSA), Solutions Expert (MCSE), and Solutions Developer (MCSD).

They are earned by passing one or more exams.

Microsoft Corporation (commonly referred to as Microsoft or MS) is an American multinational technology company headquartered in Redmond, Washington, that develops, manufactures, licenses, supports and sells computer software, consumer electronics and personal computers and services.

Its best known software products are the Microsoft Windows line of operating systems, Microsoft Office office suite, and Internet Explorer and Edge web browsers.

Its flagship hardware products are the Xbox video game consoles and the Microsoft Surface tablet lineup.

As of 2016, it was the world's largest software maker by revenue, and one of the world's most valuable companies.

Microsoft Windows (or simply Windows) is a metafamily of graphical operating systems developed, marketed, and sold by Microsoft.

It consists of several families of operating systems, each of which cater to a certain sector of the computing industry with the OS typically associated with IBM PC compatible architecture.

Active Windows families include Windows NT, Windows Embedded and Windows Phone; these may encompass subfamilies, e.g. Windows Embedded Compact (Windows CE) or Windows Server.

Defunct Windows families include Windows 9x; Windows 10 Mobile is an active product, unrelated to the defunct family Windows Mobile.

Information technology (IT) is the application of computers to store, study, retrieve, transmit, and manipulate data, or information, often in the context of a business or other enterprise.

IT is considered a subset of information and communications technology (ICT).

In 2012, Zuppo proposed an ICT hierarchy where each hierarchy level "contain[s] some degree of commonality in that they are related to technologies that facilitate the transfer of information and various types of electronically mediated communications.".

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.
