Windows (Operating System):

Microsoft Windows is a series of operating environments and operating systems created by Microsoft for use on personal computers and servers. Microsoft first introduced an operating environment named Windows in 1985, as an add-on to MS-DOS. Microsoft Windows eventually came to dominate the world personal computer market. All recent versions of Windows are fully-fledged operating systems. Windows is mostly closed source software: Microsoft Corporation owns the software's copyright and controls its distribution (http://en.wikipedia.org/wiki/Windows_operating_system).

Window:

A window is a Graphical User Interface (GUI), which usually has a rectangular shape, and contains either a graphical or textual representation of a particular software programme's output. Windows allow for one or more computer processes to be run and viewed simultaneously (http://www.google.co.za/search?hl=en&q=define%3A+window&meta=).

WMS:

An OGC Web Map Service (WMS) produces maps of spatially referenced data dynamically from geographic information. This international standard defines a "map" to be a portrayal of geographic information as a digital image file suitable for display on a computer screen. A map is not the data itself. WMS-produced maps are generally rendered in a pictorial format such as PNG, GIF or JPEG, or occasionally as vector-based graphical elements in Scalable Vector Graphics (SVG) or Web Computer Graphics Metafile (WebCGM) formats (http://en.wikipedia.org/wiki/Web_Map_Service).

XML (including AXL):

The Extensible Markup Language (XML) is a general-purpose markup language for creating special-purpose markup languages, capable of describing many different kinds of data. Its primary purpose is to facilitate the sharing of data across different systems, particularly systems connected via the Internet. Geography Markup Language (GML) used by GIS systems is based on XML (http://en.wikipedia.org/wiki/XML).

X Y Location:

The X and Y locations of a particular point are its coordinates and allow one to graphically plot the point either on a map or a diagram.

Zip:

A file compression format that enables easier and quicker transfer of data over the Internet or saving of disk space. Data in various forms such as raw data, documents and images are compressed into zip files containing one or many files. Zip files need to be decompressed (unzipped) to be opened
