2.2 Window System
In window-system environments, input and outputs are realized in windows. A
Window
is a rectangular area
on the screen the borders of which run parallel to the borders of the screen.
All tasks performed in the Line Computer Software are carried out in windows. It is possible to display and work
with several windows on the screen simultaneously.
The various windows on the screen represent the different applications. The user can work on them alternately
One application, in turn, can open several windows on the screen.
Several applications can produce outputs in their windows concurrently, irrespective of which window is currently
the active one, i.e. being edited by the user.
Windows may overlap or cover each other, which, however, does not affect the programs that are run in these
windows.
