ENVS 1500 Chapter 7 Notes Summary
Introduction
In modern operating systems, a secondary purpose has arisen that is almost as
important: the operating system provides user interface services to application
programs that assure that different programs have user interfaces that operate in the
same way.
This siplifies use of differet appliatios o the syste ad redues the users
learning curve for new programs.
We identify programs that use the operating system to provide similar interfaces as
having the same (common) look and feel.
Although the operating system can support a common look and feel across the
applications on a particular type of system, there is an important, steady trend toward
the use of Web browsers to provide a common look and feel for applications across all
types of systems.
Because the Worldwide Web is familiar to a large range of users, an organization can
simplify the training requirements and enhance its productivity by using Web-based
application interfaces as the predominant means of communication with its personnel.
A Web-based approach is also attractive to the programmers that create the
applications
Web page creation is well understood and reasonably well standardized across different
computer platforms.
The use of internal corporate Internet-like intranets to provide information resources
throughout an organization is an example of this trend, as is the capability of location-
independent Web-based access to e-mail.
In addition to the processing and display of data, documents, images, audio, and video,
there is even a growing use of Web-based productivity tools such as word processors
and spread sheet applications.
