Electronic mail, or email, is a method of exchanging digital messages between people using digital devices such as computers and mobile phones.

Email first entered substantial use in the 1960s and by the mid-1970s had taken the form now recognized as email.

Email operates across computer networks, which today is primarily the Internet.

Some early email systems required the author and the recipient to both be online at the same time, in common with instant messaging.

Today's email systems are based on a store-and-forward model.

Email servers accept, forward, deliver, and store messages.

Neither the users nor their computers are required to be online simultaneously; they need to connect only briefly, typically to a mail server or a webmail interface, for as long as it takes to send or receive messages.

In computing, Windows on Windows (commonly referred to as WOW) is a compatibility layer of 32-bit versions of the Microsoft Windows NT family of operating systems that extends NTVDM to provide limited support for running legacy 16-bit programs written for Windows 3.x or earlier.

There is a similar subsystem, known as WoW64, on 64-bit Windows versions that runs 32-bit programs.

An envelope is a common packaging item, usually made of thin flat material.

It is designed to contain a flat object, such as a letter or card.

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.

An open format is a file format for storing digital data, defined by a published specification usually maintained by a standards organization, and which can be used and implemented by anyone.

For example, an open format can be implemented by both proprietary and free and open source software, using the typical software licenses used by each.

In contrast to open formats, closed formats are considered trade secrets.

Open formats are also called free file formats if they are not encumbered by any copyrights, patents, trademarks or other restrictions (for example, if they are in the public domain) so that anyone may use them at no monetary cost for any desired purpose.
