Short for Restructured Extended Executor, an interpreted, structured, procedural script programming language created by IBM’s Mike Cowlishaw that allows programs and algorithms to be written in a clear structured way. It was designed so that it would be truly easy to use for both professionals and casual users and was designed to work in several diverse application areas — such as personal programming, command processing, application macro processing and application prototyping — where different languages are typically used. It is, however, designed to be platform-independent.
Even though Rexx is not BASIC, it can be used to write simple programs and large robust programs and can be used for many of the programs for which BASIC would otherwise be used.
Rexx evolved between the years 1979 and 1982 and, in 1983, IBM made Rexx the standard System Product interpreter for CMS in VM/SP and VM/XA. IBM selected Rexx as its SAA Procedures Language in 1987 and brought the language to all of its operating platforms, including MVS, VM, OS/400, AIX and OS/2. Today, Rexx is available in either commercial form or as freeware for operating systems including Amiga, MS/PC-DOS, most UNIX systems, VMS, 16-bit Windows, Macintosh, Windows NT and all IBM systems.
- Rich Internet Application
Abbreviated as RIA, Rich Internet Applications are Web-based applications that function as traditional desktop applications however Web browsers (or clients) are required for access but unlike traditional applications, software installation is not required, however depending on the application you usually will need to have ActiveX, Java, Flash, or similar technologies installed on the client machine.
- Rich Snippets
In Google search engine technology a snippet is the small sample of content shown to users on the Google search results page. In May 2009, Google introduced Rich Snippets, which according to Google is “a new presentation of snippets that applies Google’s algorithms to highlight structured data embedded in Web pages”. Rich Snippets are used […]

(1) Short for Advanced Encryption Standard, a symmetric 128-bit block data encryption technique developed by Belgian cryptographers Joan Daemen and Vincent Rijmen. The U.S government adopted the algorithm as its encryption technique in October 2000, replacing the DES encryption it used. AES works at multiple network layers simultaneously. The National Institute of Standards and Technology […]
Short for Radio over Internet Protocol (IP), RoIP is frequently used to describe an extension of VoIP using radio repeaters and base stations. Unlike VoIP, where two voice communication takes place between two telephones (or devices that act as telephones), RoIP is radio interoperability that is enabled through hardware devices, such as between new and […]
