A Web Map Service (WMS) is a standard protocol developed by the Open Geospatial Consortium in 1999 for serving georeferenced map images over the Internet. [1] These images are typically produced by a map server from data provided by a GIS database.
For most WMS services it is not uncommon to require 1 or more CPU seconds to produce a response. For massive parallel use cases, such a CPU-intensive service is not practical. To overcome the CPU intensive on-the-fly rendering problem, application developers started using pre-rendered map tiles.
WMS servers generate maps using parameters for user options such as the order of the layers, the styling and symbolization, the extent of the data, the data format, the projection, etc. The OGC standardized these options. Another WMS server standard is the Tile Map Service. Standard image formats include PNG, JPEG, GIF and SVG.

TMS is most widely supported by web mapping clients and servers; although there is some desktop support, the Web Map Service protocol is more widespread for enterprise mapping applications. The OpenLayers JavaScript library supports TMS natively, while the Google Maps API allows URL templating, which makes support possible for developers.

It is the most popular way to display and navigate maps, replacing other methods such as Web Map Service (WMS) which typically display a single large image, with arrow buttons to navigate to nearby areas. Google Maps was one of the first major mapping sites to use this technique.
In the same aspect, Google, one of the pioneers in web-based GIS, has developed its own language, which also uses an XML structure. Keyhole Markup Language (KML) is a file format used to display geographic data in an earth browser, such as Google Earth, Google Maps, and Google Maps for mobile browsers "Google KML definition" .
