History of televisionThe concept of television is the work of many individuals in the late 19th and early 20th centuries. The first practical transmissions of moving images over a radio system used mechanical rotating perforated disks to scan a scene into a time-varying signal that could be reconstructed at a receiver back into an approximation of the original image. Development of television was interrupted by the Second World War. After the end of the war, all-electronic methods of scanning and displaying images became standard.
Education in FranceEducation in France is organized in a highly centralized manner, with many subdivisions. It is divided into the three stages of primary education (enseignement primaire), secondary education (enseignement secondaire), and higher education (enseignement supérieur). The main age that a child starts school in France is age two and since 2022, education is obligatory from the age of three. Two year olds do not start primary school, they start preschool.
Mechanical televisionMechanical television or mechanical scan television is an obsolete television system that relies on a mechanical scanning device, such as a rotating disk with holes in it or a rotating mirror drum, to scan the scene and generate the video signal, and a similar mechanical device at the receiver to display the picture. This contrasts with vacuum tube electronic television technology, using electron beam scanning methods, for example in cathode ray tube (CRT) televisions.
TelevisionTelevision (TV) is a telecommunication medium for transmitting moving images and sound. The term can refer to a television set, or the medium of television transmission. Television is a mass medium for advertising, entertainment, news, and sports. Television became available in crude experimental forms in the late 1920s, but only after several years of further development was the new technology marketed to consumers.
French languageFrench (Standard French: Français fʁɑ̃sɛ or langue française lɑ̃ɡ fʁɑ̃sɛz) is a Romance language of the Indo-European family. It descended from the Vulgar Latin of the Roman Empire, as did all Romance languages. French evolved from Gallo-Romance, the Latin spoken in Gaul, and more specifically in Northern Gaul. Its closest relatives are the other langues d'oïl—languages historically spoken in northern France and in southern Belgium, which French (Francien) largely supplanted.
Tunisian ArabicTunisian Arabic, or simply Tunisian, is a set of dialects of Maghrebi Arabic spoken in Tunisia. It is known among its over 11 million speakers as Tounsi ˈtunsi, "Tunisian" or Derja "Everyday Language" to distinguish it from Modern Standard Arabic, the official language of Tunisia. Tunisian Arabic is mostly similar to eastern Algerian Arabic and western Libyan Arabic. As part of a dialect continuum, Tunisian merges into Algerian Arabic and Libyan Arabic at the borders of the country.
