Layers are objects which can be placed on any place of the page.

The difference between \setupbackgrounds and \flushlayer can be
seen in the example below. With \setupbackground the layer content
is put on the requested position (behind the text) after TeX has
finished the page. With \flushlayer ConTeXt starts a new page where
all collected layers are placed without any other text.

\definelayer[one]
\definelayer[two]

\setupbackgrounds[text][text][background=one]

\starttext

\input ward

\setlayer[one][x=3cm,y=3cm]{\tt One}

\page

\setlayer[two][x=3cm,y=3cm]{\tt Two}

\input ward

\flushlayer[two]

\input ward

\stoptext

As your plan is to make a document with layers only \flushlayer
is the better choice because you can do this:

\definelayer[content]

\definestartstop
  [PAGE]
  [after={\flushlayer[content]}]

\setuplayout[page]

\starttext

\startPAGE

\setlayer[content][x=3cm,y=4cm]{A}

\setlayerframed[content][x=7cm,y=2cm,frame=off,foregroundcolor=blue]{B}

\stopPAGE

\startPAGE

\setlayer[content][x=3cm,y=8cm]{\externalfigure[cow]}

\stopPAGE

\stoptext
