Wide Area Network (WAN) is a long-distance communications network that allows multiple Local Area Networks (LANs) to connect seamlessly. Large enterprises have their own private WANs to link remote offices. In Ignition, you can take advantage of a WAN to allow re-targeting from one facility to another with no additional steps for your operator.

A web server is a computer program that delivers (serves) content, such as web pages, using the Hypertext Transfer Protocol (HTTP), over the World Wide Web. The term web server can also refer to the computer or virtual machine running the program.

A web-launched program is any program started from a web browser or by using web technologies (common TCP and HTTP protocols). You can view the Ignition Gateway web page using a web browser, and the Ignition Designer and Vision Clients can be launched from the Gateway web page

Windows are the top-level unit of design for a project and the gateway to a HMI/SCADA application. They are the building blocks for all screens in a project, and act as a container for all other components that will make up a screen.

In software, a workspace generally refers to having multiple different layouts for the main interactive section of the program. For example, your email may have separate pages for incoming email vs your calendar.

In Ignition, our workspaces are designed separately for each system or module. While they all share a similar look and feel, each may have different panels displayed (Tags, Properties, Components). Selecting different objects in the Project Browser will open the different workspaces.

Web Services Description Language (WSDL) is an XML format for describing a web services interface. It is a way to describe services and how they should be bound to specific network addresses.
