SAP AG is a leading global provider of business software.
SAS (= Statement on Auditing Standards)
Statements on Auditing Standards (commonly abbreviated to SAS) are published by the American Institute of Certified Public Accountants (AICPA) and provide guidance to external auditors with regard to auditing companies.more
S-DSL (= Symmetrical Digital Subscriber Line)
Symmetrical Digital Subscriber Line (SDSL) employs a circuit-switched data transmission method with high data rates for the local loop in telephone networks. SDSL only supports services that use the same data transfer rate in both directions.
The term Seamless Communication is sometimes used to describe the growing fusion between landline and mobile telephone technology (often termed fixed-mobile convergence, or FMC). It is also used for the integration of IT-based with analog communications technologies. In short, Seamless Communication makes it possible to communicate across different technologies in a straightforward, user-friendly way.more
Service Level Agreement
A SLA is a formal document, generally part of contractual documentation for an ICT service, which defines quantitative (or qualitative) indicators or metrics that are regularly measured as a means of monitoring the service. The SLA includes all relevant rules and responsibilities. SLAs typically cover operating times and service availability.more
The Sarbanes-Oxley Act of 2002 (SOX, SarbOx, or SOA) is a United States federal law passed in response to a number of major corporate and accounting scandals. The legislation establishes new or enhanced accounting standards for all U.S. public company boards, management, and public accounting firms.
Also known as logistics or value chain, encompasses supply or value-creation process involving multiple companies. The value chain begins with the production of raw materials, proceeds through various production and transport stages, to sales and distribution, and concludes with the end-customer. A large number of companies with diverse IT systems participate in such a chain. Where companies are connected via a communications network that transcends all the various stages, the entity is called a value network. Most information exchange within a value network is effected via the Enterprise Resource Planning (ERP) systems of the participating companies.
VALIDAT guarantees the quality of data exchange via interfaces between different CAD platforms. One scenario where this is required is when a virtual team of developers located worldwide collaborate on a project.
Video on Demand
VOD is a multimedia service that allows subscribers at any time to play a video from the selection on offer (e.g. movies, educational programs or music clips). Content is stored in compressed form on video server networks and is usually delivered via a broadband network (the Internet) to be shown on a television or other suitable equipment. In the TV market, VOD is often provided as a pay-per-view or subscription service.
Voice over Wireless LAN
Also known as Voice over Wi-Fi. A convergence model for IP-based mobile voice communications (Voice over IP) on WLAN infrastructure. It makes communications possible without physical links or conventional mobile telephone networks.
Virtual Private Networks are made-to-measure, network-based voice solutions that enable companies to integrate multiple locations into a single network – without the cost of setting up their own corporate infrastructure. A VPN supports applications such as central dial-in, central switchboard, teleworking, customer telephone services and contact management.more
In a narrow sense, the term telecommunications is currently understood to mean data exchange via electrical and electronic systems, particularly telephony.more
Blend of telecommunications and informatics (another term for IT). This area of research studies the interrelationships between different communications engineering fields (digital technology, semiconductors, microelectronics and optoelectronics), and more especially the areas of IT and telecommunications that are based on these underlying technologies. One area of telematics that has risen to prominence in recent years is vehicle telematics: systems and services designed to increase transportation safety, efficiency and cost-effectiveness, and reduce the environmental impact. Vehicle telematics is making increasing use of satellite-based navigation and positioning systems (e.g. GPS, GLONASS and Galileo) to locate positions and route, plan and navigate journeys.
TETRA (= Terrestrial Trunked Radio)
TETRA (terrestrial trunked radio, originally called trans-European trunked radio) is a standard for digital trunked radio. Its special features make it particularly suitable for government agencies, specifically emergency and police services.more
Traceability means the ability to determine at any time when, where, and by whom, specific goods were obtained, produced, processed, stored, transported, consumed, or disposed of.
Wide Area Networks are designed for voice or data communications over long distances. The design of a WAN is based on the services required. The conventional analog telephone network or ISDN are suitable for telephony, while packet-oriented public data networks are intended for data transfer services.more
WAP (= Wireless Application Protocol)
The Wireless Application Protocol (WAP) is a collection of technologies and protocols designed to make Internet content available in a form adapted to mobile telephony, with its slower transmission rates and longer response times, and with the small displays of cellular telephones.more
A Webcast is a live broadcast of audiovisual content over the Internet. Webcasts are generally used for informational purposes and are often on scientific or technical topics.more
A white paper is a document giving an overview of services, standards or technical topics. Case studies, customer references, and market research findings can also be presented in white papers.more
Worldwide Interoperability for Microwave Access, a synonym for the IEEE 802.16 standard. Generic term for systems (or their air interfaces) that give wireless access to broadband networks. Thanks to its range and high data rates, WiMAX technology can be used by enterprises and private households for wireless, stationary broadband access to the Internet or other broadband networks. The standard includes a mobile version of particular interest to enterprises. It will enable nomadic employees who use notebooks to log on to the Internet or corporate intranet from any location within the company or beyond.more
Universal Mobile Telecommunications System is a third-generation (3G) mobile telephony standard that will replace GSM-based mobile communications and offer a broader range of services. UTMS supports powerful multimedia offerings. In addition to voice and audio, these can include rapid transfer of data, graphics and text as well as moving images and video. To take fuller advantage of these new capabilities, UTMS cellular phones are equipped with video cameras and color displays.more
A regulatory provision in deregulated telecommunications markets obliging the major provider (normally a former state monopolist) to allow other operators – for a fee – to use the local loop, i.e. the physical connection from the local telephone exchange to the end customer.more
USB (= Universal Serial Bus)
The Universal Serial Bus (USB) is a serial bus system used to connect a computer with external (peripheral) components. Devices or storage media (such as USB sticks) that support USB can be connected without disrupting operation (hot-plugging). A device's type and properties are automatically detected when it is plugged in.more
X.25 is a standard protocol suite for synchronous, packet-switched transmission over the telephone network. Developed by the ITU-T, X.25 is typically used for wide-area networks.more
XV5 is a CAD software product used in vehicle design, which offers significant extensions to CATIA V5 functionality in the area of surface design. This leads to much shorter development times.
