(UI) The aspects of a computer system or program which can be
seen (or heard or otherwise perceived) by the human user, and
the commands and mechanisms the user uses to control its
operation and input data.
A graphical user interface emphasises the use of pictures
for output and a pointing device such as a mouse for input
and control whereas a command line interface requires the
user to type textual commands and input at a keyboard and
produces a single stream of text as output.
A user interface contrasts with, but is typically built on top
of, an Application Program Interface (API).
