Mac OS

Mac OS is a series of graphical user interface-based operating systems developed by Apple Inc. (formerly Apple Computer, Inc.) for their Macintosh line of computer systems. The Macintosh user experience is credited with popularizing the graphical user interface. The original form of what Apple would later name the "Mac OS" was the integral and unnamed system software first introduced in 1984 with the original Macintosh, usually referred to simply as the System software.

Mashups

Mashups are certainly an exciting new genre of Web applications. The combination of data modeling technologies stemming from the Semantic Web domain and the maturation of loosely-coupled, service-oriented, platform-agnostic communication protocols is finally providing the infrastructure needed to start developing applications that can leverage and integrate the massive amount of information that is available on the Web. As mashup applications gain higher visibility, it will be interesting to see how the genre impacts social issues such as fair-use and intellectual property as well as other application domains that integrate data across organizational boundaries, such as grid computing and business-to-business workflow management.
For a deeper-dive into mashup development, stay tuned for the launching of a new series of tutorials on developerWorks that will teach you how to construct your own mashups. In fact, the series will even teach you how to use Semantic Web technology and ontologies to enable others to create their own mashups.

Mashup (web application hybrid)

In web development, a mashup is a web page or application that uses and combines data, presentation or functionality from two or more sources to create new services.

The term implies easy, fast integration, frequently using open APIs (an interface implemented by a software program that enables it to interact with other software) and data sources to produce enriched results that were not necessarily the original reason for producing the raw source data.

The main characteristics of the mashup are combination, visualization, and aggregation. Mashup is important to make existing data more useful, moreover for personal and professional use.

To be able to permanently access the data of other services, mashups are generally client applications or hosted online. Since 2010, two major mashup vendors have added support for hosted deployment based on Cloud computing solutions; that are Internet-based computing, whereby shared resources, software, and information are provided to computers and other devices on demand, like the electricity grid

In the past years, more and more Web applications have published APIs that enable software developers to easily integrate data and functions instead of building them by themselves. Mashups can be considered to have an active role in the evolution of social software and Web 2.0. Mashups composition tools are usually simple enough to be used by end-users. They generally do not require programming skills, they rather support visual wiring of GUI widgets, services and components together. Therefore, these tools contribute to a new vision of the Web, where users are able to contribute.

The term mashup is also used to describe a remix[1] of digital data.
