Voice over Internet Protocol (VoIP), also known as IP telephony, refers to a set of technologies used for voice communication sessions over Internet Protocol (IP) networks, such as the Internet. VoIP enables voice calls to be transmitted as data packets, facilitating various methods of voice communication, including traditional applications like Skype, Microsoft Teams, Google Voice, and VoIP phones. Regular telephones can also be used for VoIP by connecting them to the Internet via analog telephone adapters (ATAs), which convert traditional telephone signals into digital data packets that can be transmitted over IP networks.
The next-generation network (NGN) is a body of key architectural changes in telecommunication core and access networks. The general idea behind the NGN is that one network transports all information and services by encapsulating these into IP packets, similar to those used on the Internet. NGNs are commonly built around the Internet Protocol, and therefore the term all IP is also sometimes used to describe the transformation of formerly telephone-centric networks toward NGN.
Astrovirtel is a data archive used as virtual astronomical observatory. The project was funded from 2000 until 2003 and supported by the European Commission's Access to Research Infrastructures action of the Improving Human Potential Programme and managed by the Space Telescope European Coordinating Facility (ST-ECF) on behalf of European Space Agency and European Southern Observatory (ESO).
The Astrophysical Virtual Observatory (AVO) project conducted a research and demonstration programme on the scientific requirements and technologies necessary to build a virtual observatory for European astronomy. The AVO has been jointly funded by the European Commission with six European organisations participating in a three-year Phase-A work programme, valued at 5 million euro. The partner organisations were the European Southern Observatory (ESO) in Munich, Germany, the European Space Agency (ESA), AstroGrid, the CNRS-supported Centre de Données Astronomiques de Strasbourg (CDS), the University Louis Pasteur in Strasbourg, France, the CNRS-supported TERAPIX astronomical data centre at the Institut d'Astrophysique in Paris, France, and the Jodrell Bank Observatory of the Victoria University of Manchester, United Kingdom.
The International Virtual Observatory Alliance (IVOA) is a worldwide scientific organisation formed in June 2002. Its mission is to facilitate international coordination and collaboration necessary for enabling global and integrated access to data gathered by astronomical observatories. An information system allowing such an access is called a virtual observatory. The main task of the organisation so far has focused on defining standards to ensure interoperability of the different virtual observatory projects already existing or in development.
The US National Virtual Observatory'-NVO- was conceived to allow scientists to access data from multiple astronomical observatories, including ground and space-based facilities, through a single portal. Originally, the National Science Foundation (NSF) funded the information technology research that created the basic NVO infrastructure through a multi-organization collaborative effort. The NVO was more than a “digital library”; it was a vibrant, growing online research facility akin to a bricks-and-mortar observatory for professional astronomers.
The D-Grid Initiative was a government project to fund computer infrastructure for education and research (e-Science) in Germany. It uses the term grid computing. D-Grid started September 1, 2005 with six community projects and an integration project (DGI) as well as several partner projects.
A virtual observatory (VO) is a collection of interoperating data archives and software tools which utilize the internet to form a scientific research environment in which research programs can be conducted. Historically addressing astronomical subjects, space physics and geosciences have also been a focus of VO development.
ONO was a Spanish broadband communication and entertainment company, delivering integrated telephone, television and Internet services to its residential customers. In this segment, it has 3.7 million services contracted and over six million users.
The Cubic Kilometre Neutrino Telescope, or KM3NeT, is a European research infrastructure located at the bottom of the Mediterranean Sea. It hosts the next-generation neutrino telescope with water Cherenkov detectors.
Infrastructure as a service (IaaS) is a cloud computing service model where a cloud services vendor provides computing resources such as storage, network, servers, and virtualization. This service frees users from maintaining their own data center, but they must install and maintain the operating system and application software. Iaas provides users high-level APIs to control details of underlying network infrastructure such as backup, data partitioning, scaling, security and physical computing resources. Services can be scaled on-demand by the user. According to the Internet Engineering Task Force (IETF), such infrastructure is the most basic cloud-service model. IaaS can be hosted in a public cloud, a private cloud, or a hybrid cloud.
The Nordic Data Grid Facility, or NDGF, is a common e-Science infrastructure provided by the Nordic countries for scientific computing and data storage. It is the first and so far only internationally distributed WLCG Tier1 center, providing computing and storage services to experiments at CERN.
Platform as a service (PaaS) or application platform as a service (aPaaS) or platform-based service is a cloud computing service model where users provision, instantiate, run and manage a modular bundle of a computing platform and applications, without the complexity of building and maintaining the infrastructure associated with developing and launching application(s), and to allow developers to create, develop, and package such software bundles.
Tuenti Technologies, S.L.U is a mobile virtual network operator (MVNO) that operates with the Tuenti brand owned by Telefónica. It is a Spain-based tech company that focuses on providing a cloud-based services through its own application and its website to their customers.

The Science Programme of the European Space Agency is a long-term programme of space science and space exploration missions. Managed by the agency's Directorate of Science, The programme funds the development, launch, and operation of missions led by European space agencies and institutions through generational campaigns. Horizon 2000, the programme's first campaign, facilitated the development of eight missions between 1985 and 1995 including four "cornerstone missions" – SOHO and Cluster II, XMM-Newton, Rosetta, and Herschel. Horizon 2000 Plus, the programme's second campaign, facilitated the development of Gaia, LISA Pathfinder, and BepiColombo between 1995 and 2005. The programme's current campaign since 2005, Cosmic Vision, has so far funded the development of ten missions including three flagship missions, JUICE, Athena, and LISA. The programme's upcoming fourth campaign, Voyage 2050, is currently being drafted. Collaboration with agencies and institutions outside of Europe occasionally occur in the Science Programme, including a collaboration with NASA on Cassini–Huygens and the CNSA on SMILE.
