EECS 1012 Lecture 24 Notes
Introduction
A standard look
• As we noted previously, these services enable the system to provide a standard look and
feel for different applications extending, even, to the Web interface.
• They simplify and extend the graphic capabilities of application programs
• They improve the capability of programs to communicate with each other and to pass
data from one application to another
• They provide the ability to launch an application program from within another
• They provide e-mail and other communication capabilities
• They provide document and graphical storage services at a more sophisticated level
than was found previously in traditional OS file management facilities.
• By integrating these capabilities into the operating system, the system can assure that
every application program responds in similar ways to user actions.
• Integration also provides smooth and seamless interaction between the different
applications.
• Just as the file manager assures a consistent representation and interface for file
manipulation across different devices
• So these new services provide the user with a more powerful and easier to use way to
access his program applications.
• The overall effect is an increased emphasis on the user interface and new ways of
working that are more oriented toward the work to be accomplished and less to the
launching and manipulation of application programs.
• Although ay of these tools are foud i a shell, they are ore tightly itegrated
into the operating system than was true of previous shells.
• The addition of new operating system services is intimately tied to improved
programming methods, particularly object-oriented programming.
