Full application
download
An entire application, including all executables
and data files, transfers from one system to
another in a single operation.
Files related to the file authentication process
and device configuration settings can be
included in a full application download. During
this process, SRAM is cleared.
Following a full application download, the
device restarts and the file authentication
module is invoked. If application files are
authenticated and config.sys *GO variable is
set, then the application executes.

A subset of application executables, font files,
or data files transfer from one system to
another to modify or update an existing
