Information: - The European Union (EU) is a political and economic union of member states that are located primarily in Europe. It has an area of , and an estimated population of over 510 million. The EU has developed an internal single market through a standardised system of laws that apply in all member states. EU policies aim to ensure the free movement of people, goods, services, and capital within the internal market, enact legislation in justice and home affairs, and maintain common policies on trade, agriculture, fisheries, and regional development. Within the Schengen Area, passport controls have been abolished. A monetary union was established in 1999 and came into full force in 2002, and is composed of 19 EU member states which use the euro currency. - A country code top-level domain (ccTLD) is an Internet top-level domain generally used or reserved for a country, sovereign state, or dependent territory identified with a country code. - Cybersquatting (also known as domain squatting), according to the United States federal law known as the Anticybersquatting Consumer Protection Act, is registering, trafficking in, or using an Internet domain name with bad faith intent to profit from the goodwill of a trademark belonging to someone else. The cybersquatter then offers to sell the domain to the person or company who owns a trademark contained within the name at an inflated price. - This is the list of countries by number of Internet hosts , based on 2012 figures from the CIA World Factbook . Several dependent territories , not fully recognized states , and non-state territories are also listed . The European Union host ( . eu ) is mostly composed of French , Polish and German hosts . - The Schengen Area is an area comprising 26 European states that have officially abolished passport and any other type of border control at their mutual borders. The area mostly functions as a single country for international travel purposes, with a common visa policy. The area is named after the Schengen Agreement. States in the Schengen Area have eliminated border controls with other Schengen members and strengthened border controls with non-Schengen countries. - A single market is a type of trade bloc in which most trade barriers have been removed (for goods) with some common policies on product regulation, and freedom of movement of the factors of production (capital and labour) and of enterprise and services. The goal is that the movement of capital, labour, goods, and services between the members is as easy as within them. The physical (borders), technical (standards) and fiscal (taxes) barriers among the member states are removed to the maximum extent possible. These barriers obstruct the freedom of movement of the four factors of production. - .eu is the country code top-level domain (ccTLD) for the European Union (EU). Launched on 7 December 2005, the domain is available for organisations in and residents of EU member states. The TLD is administered by EURid, a consortium originally consisting of the national ccTLD registry operators of Belgium, Sweden, and Italy, joined later by the national registry operator of the Czech Republic. Trademark owners were able to submit registrations through a sunrise period, in an effort to prevent cybersquatting. Full registration started on 7 April 2006. - An economic union is a type of trade bloc which is composed of a common market with a customs union. The participant countries have both common policies on product regulation, freedom of movement of goods, services and the factors of production (capital and labour) and a common external trade policy. When an economic union involves unifying currency it becomes a economic and monetary union. - Europe is a continent that comprises the westernmost part of Eurasia. Europe is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, and the Mediterranean Sea to the south. To the east and southeast, Europe is generally considered as separated from Asia by the watershed divides of the Ural and Caucasus Mountains, the Ural River, the Caspian and Black Seas, and the waterways of the Turkish Straits. Yet the non-oceanic borders of Europea concept dating back to classical antiquityare arbitrary. The primarily physiographic term "continent" as applied to Europe also incorporates cultural and political elements whose discontinuities are not always reflected by the continent's current overland boundaries. - A passport is a travel document, usually issued by a country's government, that certifies the identity and nationality of its holder for the purpose of international travel. Standard passports may contain information such as the holder's name, place and date of birth, photograph, signature, and other identifying information. Passports are moving towards including biometric information in a microchip embedded in the document, making them machine-readable and difficult to counterfeit. - EURid vzw/asbl (European Registry for Internet Domains) is a non-profit organisation appointed by the European Commission on 8 April 2003 as the domain name registry to operate the new .eu top-level domain.
