I am new at GeoServer. I connected to database from admin panel and published layers. But I could not understand difference of WMS, WFS and REST service.
What is the difference?

Web Map Service (WMS): The Standard Web Map Service (WMS) provides a simple HTTP interface for requesting map images from one or more distributed servers on the Internet. A WMS request defines what the layer and the geographical area of interest to be processed. The response to the request is one or more images of the map (in JPEG, PNG, ...) that can be displayed in a web browser. The Standard also supports the ability to specify if the image returned should be transparent, so you can combine any of layers from different servers.
Web Feature Service (WFS): The Standard Web Feature Service (WFS) provides, similar to the WMS, a simple HTTP interface for requesting direct geographic objects (images and maps) from one or more distributed servers on the Internet. The mechanisms of request and response are similar to the WMS, with the difference that images are not returned, but the descriptions of individual spatial objects contained within the area of interest to be processed (spatial coordinates and any alphanumeric attributes).
