Conferences - A conference is a meeting of people that "confer" about a topic. Business conferences are events organized by an association, individual, publication or private company for the purpose of networking, education or to discuss a business topic with a range of speakers. They can also be organized by either a non-profit or for-profit organization. The latter is called a conference company. Business conferences are often held at convention centers and large hotels with conference facilities. An act or process of coming together as an assembly for a common purpose. A meeting is a gathering of two or more people that has been convened for the purpose of achieving a common goal through verbal interaction, such as sharing information or reaching agreement. Meetings may occur face to face or virtually, as mediated by communications technology, such as a telephone conference call, a skyped conference call or a videoconference. Conference meeting room - A conference hall or conference room is a room provided for singular events such as business conferences. It is commonly found at large hotels and convention centers though many other establishments, including even hospitals, have one. Sometimes other rooms are modified for large conferences such as arenas or concert halls. Aircraft have been fitted out with conference rooms. Conference rooms can be windowless for security purposes. An example of one such room is in the Pentagon, known as the Tank. Typically, the facility provides furniture, overhead projectors, stage lighting, and a sound system. Smoking is normally prohibited in conference halls even when other parts of buildings permit smoking. Sometimes the term 'conference hall' is used synonymously with 'conference center'. An assembly hall is traditionally a building used for the purposes of holding deliberative assemblies. An example is the Assembly Hall in Washington, Mississippi. London is the capital of England and the United Kingdom (UK). It is Britain's largest and most populous metropolitan area. A major settlement for two millennia, its history goes back to its founding by the Romans, who called it Londinium. London's core, the ancient City of London, or the 'square mile' financial district, largely retains its mediaeval boundaries. Since at least the 19th century, the name "London" has also referred to the metropolis developed around this core. In modern times, the bulk of this conurbation forms the London region and the Greater London administrative area, with its own elected mayor and assembly. The London Assembly is an elected body, part of the Greater London Authority, that scrutinises the activities of the Mayor of London and has the power, with a two-thirds majority, to amend the Mayor's annual budget. The Assembly was established in 2000 and is headquartered at City Hall on the south side of the River Thames close to Tower Bridge.
