The Treaty of Verdun of 843 partitioned the empire, with West Francia evolving into the Kingdom of France . In the High Middle Ages , France was a powerful but decentralized feudal kingdom, but from
11700-630: The basic concept which underlies all electronic digital computers. By 1938, the United States Navy had developed an electromechanical analog computer small enough to use aboard a submarine . This was the Torpedo Data Computer , which used trigonometry to solve the problem of firing a torpedo at a moving target. During World War II similar devices were developed in other countries as well. Early digital computers were electromechanical ; electric switches drove mechanical relays to perform
11850-530: The best Arithmetician that euer [ sic ] breathed, and he reduceth thy dayes into a short number." This usage of the term referred to a human computer , a person who carried out calculations or computations . The word continued to have the same meaning until the middle of the 20th century. During the latter part of this period, women were often hired as computers because they could be paid less than their male counterparts. By 1943, most human computers were women. The Online Etymology Dictionary gives
12000-563: The calculation. These devices had a low operating speed and were eventually superseded by much faster all-electric computers, originally using vacuum tubes . The Z2 , created by German engineer Konrad Zuse in 1939 in Berlin , was one of the earliest examples of an electromechanical relay computer. In 1941, Zuse followed his earlier machine up with the Z3 , the world's first working electromechanical programmable , fully automatic digital computer. The Z3
12150-504: The climate became milder; from approximately 7,000 BC, this part of Western Europe entered the Neolithic era, and its inhabitants became sedentary . After demographic and agricultural development between the 4th and 3rd millennia BC, metallurgy appeared , initially working gold, copper and bronze , then later iron . France has numerous megalithic sites from the Neolithic, including
12300-554: The concept of a programmable computer. Considered the " father of the computer ", he conceptualized and invented the first mechanical computer in the early 19th century. After working on his difference engine he announced his invention in 1822, in a paper to the Royal Astronomical Society , titled "Note on the application of machinery to the computation of astronomical and mathematical tables". He also designed to aid in navigational calculations, in 1833 he realized that
12450-789: The constitutional July Monarchy ; French troops began the conquest of Algeria . Unrest led to the French Revolution of 1848 and the end of the July Monarchy. The abolition of slavery and introduction of male universal suffrage was re-enacted in 1848. In 1852, president of the French Republic, Louis-Napoléon Bonaparte , Napoleon I's nephew, was proclaimed emperor of the Second Empire , as Napoleon III. He multiplied French interventions abroad, especially in Crimea , Mexico and Italy . Napoleon III
12600-690: The core of general-purpose devices such as personal computers and mobile devices such as smartphones . Computers power the Internet , which links billions of computers and users. Early computers were meant to be used only for calculations. Simple manual instruments like the abacus have aided people in doing calculations since ancient times.

More sophisticated electrical machines did specialized analog calculations in
12750-492: The course of the defeat in the Algerian War . The current Fifth Republic was formed in 1958 by Charles de Gaulle . Algeria and most French colonies became independent in the 1960s, with the majority retaining close economic and military ties with France . France retains its centuries-long status as a global centre of art , science , and philosophy . It hosts the fourth-largest number of UNESCO World Heritage Sites and
12900-493: The data signals do not have to travel long distances. Since ENIAC in 1945, computers have advanced enormously, with modern SoCs (such as the Snapdragon 865) being the size of a coin while also being hundreds of thousands of times more powerful than ENIAC, integrating billions of transistors, and consuming only a few watts of power. The first mobile computers were heavy and ran from mains power. The 50 lb (23 kg) IBM 5100
13050-507: The decision of the British Government to cease funding. Babbage's failure to complete the analytical engine can be chiefly attributed to political and financial difficulties as well as his desire to develop an increasingly sophisticated computer and to move ahead faster than anyone else could follow. Nevertheless, his son, Henry Babbage , completed a simplified version of the analytical engine's computing unit (the mill ) in 1888. He gave
13200-414: The defeat of Nazi Germany, in 1945. The Z4 was Zuse's final target for the Z3 design. Like the earlier Z2 , it comprised a combination of mechanical memory and electromechanical logic.

The principle of
13500-479: The doll is at the Musée d'Art et d'Histoire of Neuchâtel , Switzerland , and still operates. In 1831–1835, mathematician and engineer Giovanni Plana devised a Perpetual Calendar machine , which through a system of pulleys and cylinders could predict the perpetual calendar for every year from 0 CE (that is, 1 BCE) to 4000 CE, keeping track of leap years and varying day length. The tide-predicting machine invented by
13650-475: The early 11th century. The astrolabe was invented in the Hellenistic world in either the 1st or 2nd centuries BCE and is often attributed to Hipparchus . A combination of the planisphere and dioptra , the astrolabe was effectively an analog computer capable of working out several different kinds of problems in spherical astronomy . An astrolabe incorporating a mechanical calendar computer and gear -wheels
13800-473: The early 2000s. These smartphones and tablets run on a variety of operating systems and recently became the dominant computing device on the market. These are powered by System on a Chip (SoCs), which are complete computers on a microchip the size of a coin.

13950-399: The early 20th century. The first digital electronic calculating machines were developed during World War II , both electromechanical and using thermionic valves . The first semiconductor transistors in the late 1940s were followed by the silicon -based MOSFET (MOS transistor) and monolithic integrated circuit chip technologies in the late 1950s, leading to the microprocessor and
14100-516: The empire, leaving England and Aquitaine to the Plantagenets. Charles IV the Fair died without an heir in 1328. The crown passed to Philip of Valois , rather than Edward of Plantagenet, who became Edward III of England . During the reign of Philip, the monarchy reached the height of its medieval power. However Philip's seat on the throne was contested by Edward in 1337, and England and France entered
14250-594: The ensuing uprising of European monarchies against his rule, Napoleon was defeated. About a million Frenchmen died during the Napoleonic Wars . After his brief return from exile, Napoleon was finally defeated in 1815 at the Battle of Waterloo , and the Bourbon monarchy was restored with new constitutional limitations. The discredited Bourbon dynasty was overthrown by the July Revolution of 1830, which established
14400-473: The exact definition of the term "microprocessor", it is largely undisputed that the first single-chip microprocessor was the Intel 4004 , designed and realized by Federico Faggin with his silicon-gate MOS IC technology, along with Ted Hoff , Masatoshi Shima and Stanley Mazor at Intel . In the early 1970s, MOS IC technology enabled the integration of more than 10,000 transistors on a single chip. System on
14550-503: The first Colossus. After a functional test in December 1943, Colossus was shipped to Bletchley Park, where it was delivered on 18 January 1944 and attacked its first message on 5 February. Colossus was the world's first electronic digital programmable computer. It used a large number of valves (vacuum tubes). It had paper-tape input and was capable of being configured to perform a variety of boolean logical operations on its data, but it
14700-725: The first attested use of computer in the 1640s, meaning 'one who calculates'; this is an "agent noun from compute (v.)". The Online Etymology Dictionary states that the use of the term to mean " 'calculating machine' (of any type) is from 1897." The Online Etymology Dictionary indicates that the "modern use" of the term, to mean 'programmable digital electronic computer' dates from "1945 under this name; [in a] theoretical [sense] from 1937, as Turing machine ". The name has remained, although modern computers are capable of many higher-level functions. Devices have been used to aid computation for thousands of years, mostly using one-to-one correspondence with fingers . The earliest counting device
14850-582: The forefront of the development of a supranational European Union , notably by signing the Maastricht Treaty in 1992, establishing the eurozone in 1999 and signing the Treaty of Lisbon in 2007. France has fully reintegrated into NATO and since participated in most NATO-sponsored wars. Since the 19th century, France has received many immigrants , often male foreign workers from European Catholic countries who generally returned home when not employed. During

The machine was about a century ahead of its time. All the parts for his machine had to be made by hand – this was a major problem for a device with thousands of parts. Eventually, the project was dissolved with
15150-927: The four major rivers Seine , the Loire , the Garonne , the Rhône and their tributaries, whose combined catchment includes over 62% of the metropolitan territory. The Rhône divides the Massif Central from the Alps and flows into the Mediterranean Sea at the Camargue . The Garonne meets the Dordogne just after Bordeaux, forming the Gironde estuary , the largest estuary in Western Europe which after approximately 100 kilometres (62 mi) empties into
15300-462: The integrated circuit in July 1958, successfully demonstrating the first working integrated example on 12 September 1958. In his patent application of 6 February 1959, Kilby described his new device as "a body of semiconductor material ... wherein all the components of the electronic circuit are completely integrated". However, Kilby's invention was a hybrid integrated circuit (hybrid IC), rather than
15450-411: The integration. In 1876, Sir William Thomson had already discussed the possible construction of such calculators, but he had been stymied by the limited output torque of the ball-and-disk integrators . In a differential analyzer, the output of one integrator drove the input of the next integrator, or a graphing output. The torque amplifier was the advance that allowed these machines to work. Starting in
15600-437: The internal working was in binary. The machine had a large repertoire of instructions including square root, MAX, MIN and sine. Conditional tests included tests for infinity. When delivered to ETH Zurich in 1950 the machine had a conditional branch facility added and could print on a Mercedes typewriter. There were two program tapes where the second could be used to hold a subroutine. (Originally six were planned.) In 1944, Zuse
15750-531: The largest among European Union members. France's total land area, with its overseas departments and territories (excluding Adélie Land ), is 643,801 km (248,573 sq mi), 0.45% of the total land area on Earth. France possesses a wide variety of landscapes, from coastal plains in the north and west to mountain ranges of the Alps in the southeast, the Massif Central in the south-central and Pyrenees in
15900-569: The machine did make use of valves to generate its 125 kHz clock waveforms and in the circuitry to read and write on its magnetic drum memory , so it was not the first completely transistorized computer. That distinction goes to the Harwell CADET of 1955, built by the electronics division of the Atomic Energy Research Establishment at Harwell . The metal–oxide–silicon field-effect transistor (MOSFET), also known as
16050-459: The meaning "free" was adopted because, after the conquest of Gaul , only Franks were free of taxation, or more generally because they had the status of freemen in contrast to servants or slaves. The etymology of *Frank is uncertain. It is traditionally derived from the Proto-Germanic word * frankōn , which translates as "javelin" or "lance" (the throwing axe of the Franks was known as
16200-627: The mid-14th to the mid-15th centuries, France was plunged into a dynastic conflict with England known as the Hundred Years' War . In the 16th century, the French Renaissance saw culture flourish and a French colonial empire rise. Internally, France was dominated by the conflict with the House of Habsburg and the French Wars of Religion between Catholics and Huguenots . France was successful in
16350-452: The modern computer was proposed by Alan Turing in his seminal 1936 paper, On Computable Numbers . Turing proposed a simple device that he called "Universal Computing machine" and that is now known as a universal Turing machine . He proved that such a machine is capable of computing anything that is computable by executing instructions (program) stored on tape, allowing the machine to be programmable. The fundamental concept of Turing's design
16500-403: The more famous Sir William Thomson. The art of mechanical analog computing reached its zenith with the differential analyzer , built by H. L. Hazen and Vannevar Bush at MIT starting in 1927. This built on the mechanical integrators of James Thomson and the torque amplifiers invented by H. W. Nieman. A dozen of these devices were built before their obsolescence became obvious. By the 1950s,
16650-633: The most-used language in diplomacy, science, and literature until the 20th century. France took control of territories in the Americas, Africa and Asia. In 1685, Louis XIV revoked the Edict of Nantes , forcing thousands of Huguenots into exile and published the Code Noir providing the legal framework for slavery and expelling Jews from French colonies. Under the wars of Louis XV (r. 1715–1774), France lost New France and most Indian possessions after its defeat in
16800-454: The newly established kingdoms. These victories led to the worldwide expansion of French revolutionary ideals and reforms, such as the metric system , Napoleonic Code and Declaration of the Rights of Man. In 1812 Napoleon attacked Russia , reaching Moscow. Thereafter his army disintegrated through supply problems, disease, Russian attacks, and finally winter. After this catastrophic campaign and
16950-501: The off-and-on Hundred Years' War . Boundaries changed, but landholdings inside France by English Kings remained extensive for decades. With charismatic leaders, such as Joan of Arc , French counterattacks won back most English continental territories. France was struck by the Black Death , from which half of the 17 million population died. The French Renaissance saw cultural development and standardisation of French, which became
17100-616: The palace (head of household). One mayor of the palace, Charles Martel , defeated an Umayyad invasion of Gaul at the Battle of Tours (732). His son, Pepin the Short , seized the crown of Francia from the weakened Merovingians and founded the Carolingian dynasty . Pepin's son, Charlemagne , reunited the Frankish kingdoms and built an empire across Western and Central Europe . Proclaimed Holy Roman Emperor by Pope Leo III and thus establishing
17250-486: The practical use of MOS transistors as memory cell storage elements, leading to the development of MOS semiconductor memory , which replaced earlier magnetic-core memory in computers. The MOSFET led to the microcomputer revolution , and became the driving force behind the computer revolution . The MOSFET is the most widely used transistor in computers, and is the fundamental building block of digital electronics . The next great advance in computing power came with
17400-617: The primary source of legitimacy , undermined the power of and support for the monarchy and was a factor in the Revolution. The French Revolution was a period of political and societal change that began with the Estates General of 1789 , and ended with the coup of 18 Brumaire in 1799 and the formation of the French Consulate . Many of its ideas are fundamental principles of liberal democracy , while its values and institutions remain central to modern political discourse. Its causes were
17550-569: The remainder of Gaul and overcame a revolt by Gallic chieftain Vercingetorix in 52 BC. Gaul was divided by Augustus into provinces and many cities were founded during the Gallo-Roman period , including Lugdunum (present-day Lyon ), the capital of the Gauls. In 250–290 AD, Roman Gaul suffered a crisis with its fortified borders attacked by barbarians . The situation improved in the first half of
17700-532: The results of operations to be saved and retrieved. It was not until the mid-20th century that the word acquired its modern definition; according to the Oxford English Dictionary , the first known use of the word computer was in a different sense, in a 1613 book called The Yong Mans Gleanings by the English writer Richard Brathwait : "I haue [ sic ] read the truest computer of Times, and
17850-449: The revolt was a political failure (the Gaullist party emerged stronger than before) it announced a split between the French and de Gaulle, who resigned. In the post-Gaullist era, France remained one of the most developed economies in the world but faced crises that resulted in high unemployment rates and increasing public debt. In the late 20th and early 21st centuries, France has been at
18000-575: The same time that digital calculation replaced analog. The engineer Tommy Flowers , working at the Post Office Research Station in London in the 1930s, began to explore the possible use of electronics for the telephone exchange . Experimental equipment that he built in 1934 went into operation five years later, converting a portion of the telephone exchange network into an electronic data processing system, using thousands of vacuum tubes . In
18150-538: The second-largest behind the British Empire . Including metropolitan France, the total area reached almost 13 million square kilometres in the 1920s and 1930s, 9% of the world's land. Known as the Belle Époque , the turn of the century was characterised by optimism, regional peace, economic prosperity and technological, scientific and cultural innovations. In 1905, state secularism was officially established . France
18300-468: The southwest. Due to its numerous overseas departments and territories scattered across the planet, France possesses the second-largest exclusive economic zone (EEZ) in the world, covering 11,035,000 km (4,261,000 sq mi). Its EEZ covers approximately 8% of the total surface of all the EEZs of the world. Metropolitan France has a wide variety of topographical sets and natural landscapes. During
18450-647: The state and reinforced royal power. He destroyed castles of defiant lords and denounced the use of private armies. By the end of the 1620s, Richelieu established "the royal monopoly of force". France fought in the Thirty Years' War , supporting the Protestant side against the Habsburgs. From the 16th to the 19th century, France was responsible for about 10% of the transatlantic slave trade . During Louis XIV 's minority, trouble known as The Fronde occurred. This rebellion
18600-478: The stored-program computer was laid out by Alan Turing in his 1936 paper. In 1945, Turing joined the National Physical Laboratory and began work on developing an electronic stored-program digital computer. His 1945 report "Proposed Electronic Calculator" was the first specification for such a device. John von Neumann at the University of Pennsylvania also circulated his First Draft of a Report on
18750-443: The success of digital electronic computers had spelled the end for most analog computing machines, but analog computers remained in use during the 1950s in some specialized applications such as education ( slide rule ) and aircraft ( control systems ). Claude Shannon 's 1937 master's thesis laid the foundations of digital computing, with his insight of applying Boolean algebra to the analysis and synthesis of switching circuits being
18900-473: The unoccupied territory. Free France , the government-in-exile led by Charles de Gaulle , was set up in London. From 1942 to 1944, about 160,000 French citizens, including around 75,000 Jews , were deported to death and concentration camps . On 6 June 1944, the Allies invaded Normandy , and in August they invaded Provence . The Allies and French Resistance emerged victorious, and French sovereignty

The first modern analog computer was a tide-predicting machine , invented by Sir William Thomson (later to become Lord Kelvin) in 1872. The differential analyser , a mechanical analog computer designed to solve differential equations by integration using wheel-and-disc mechanisms, was conceptualized in 1876 by James Thomson , the elder brother of
19200-698: The world . Metropolitan France shares borders with Belgium and Luxembourg to the north, Germany to the northeast, Switzerland to the east, Italy and Monaco to the southeast, Andorra and Spain to the south, and a maritime border with the United Kingdom to the northwest. Its metropolitan area extends from the Rhine to the Atlantic Ocean and from the Mediterranean Sea to the English Channel and
19350-457: Was invaded by Germany and defended by Great Britain at the start of World War I in August 1914. A rich industrial area in the north was occupied. France and the Allies emerged victorious against the Central Powers at tremendous human cost. It left 1.4 million French soldiers dead, 4% of its population. Interwar was marked by intense international tensions and social reforms introduced by
19500-406: Was a 16-transistor chip built by Fred Heiman and Steven Hofstein at RCA in 1962. General Microelectronics later introduced the first commercial MOS IC in 1964, developed by Robert Norman. Following the development of the self-aligned gate (silicon-gate) MOS transistor by Robert Kerwin, Donald Klein and John Sarace at Bell Labs in 1967, the first silicon-gate MOS IC with self-aligned gates
19650-511: Was a founding member of NATO and attempted to regain control of French Indochina , but was defeated by the Viet Minh in 1954. France faced another anti-colonialist conflict in Algeria , then part of France and home to over one million European settlers ( Pied-Noir ). The French systematically used torture and repression, including extrajudicial killings to keep control. This conflict nearly led to
19800-511: Was an early example. Later portables such as the Osborne 1 and Compaq Portable were considerably lighter but still needed to be plugged in. The first laptops, such as the Grid Compass , removed this requirement by incorporating batteries – and with the continued miniaturization of computing resources and advancements in portable battery life, portable computers grew in popularity in the 2000s. The same developments allowed manufacturers to integrate computing resources into cellular mobile phones by
19950-473: Was built with 2000 relays , implementing a 22 bit word length that operated at a clock frequency of about 5–10 Hz . Program code was supplied on punched film while data could be stored in 64 words of memory or supplied from the keyboard.

Lyons's LEO I computer, modelled closely on
20250-443: Was developed by Federico Faggin at Fairchild Semiconductor in 1968. The MOSFET has since become the most critical device component in modern ICs. The development of the MOS integrated circuit led to the invention of the microprocessor , and heralded an explosion in the commercial and personal use of computers. While the subject of exactly which device was the first microprocessor is contentious, partly due to lack of agreement on
20400-825: Was developed in the late 16th century and found application in gunnery, surveying and navigation. The planimeter was a manual instrument to calculate the area of a closed figure by tracing over it with a mechanical linkage. The slide rule was invented around 1620–1630, by the English clergyman William Oughtred , shortly after the publication of the concept of the logarithm . It is a hand-operated analog computer for doing multiplication and division. As slide rule development progressed, added scales provided reciprocals, squares and square roots, cubes and cube roots, as well as transcendental functions such as logarithms and exponentials, circular and hyperbolic trigonometry and other functions . Slide rules with special scales are still used for quick performance of routine calculations, such as
20550-451: Was divided into Germanic kingdoms and a remaining Gallo-Roman territory. Celtic Britons , fleeing the Anglo-Saxon settlement of Britain , settled in west Armorica ; the Armorican peninsula was renamed Brittany and Celtic culture was revived. The first leader to unite all Franks was Clovis I , who began his reign as king of the Salian Franks in 481, routing the last forces of the Roman governors in 486. Clovis said he would be baptised
20700-479: Was driven by feudal lords and sovereign courts as a reaction to the royal absolute power . The monarchy reached its peak during the 17th century and reign of Louis XIV. By turning lords into courtiers at the Palace of Versailles , his command of the military went unchallenged. The "Sun King" made France the leading European power. France became the most populous European country and had tremendous influence over European politics, economy, and culture. French became
20850-405: Was executed in January 1793. After another revolt in June 1793 , the constitution was suspended and power passed from the National Convention to the Committee of Public Safety . About 16,000 people were executed in a Reign of Terror , which ended in July 1794 . Weakened by external threats and internal opposition, the Republic was replaced in 1795 by the Directory . Four years later in 1799,
21000-450: Was headed by Albert Betz . But when it was presented to scientists of the AVA the roar of the approaching front could already be heard, so the computer was transported with a truck of the Wehrmacht to Hinterstein in Bad Hindelang in southern Bavaria, where Konrad Zuse met Wernher von Braun . By 1947 it was possible for constants to be entered by the punched tape. In 1949, the Swiss mathematician Eduard Stiefel , after coming back from
21150-449: Was invented by Abi Bakr of Isfahan , Persia in 1235. Abū Rayhān al-Bīrūnī invented the first mechanical geared lunisolar calendar astrolabe, an early fixed- wired knowledge processing machine with a gear train and gear-wheels, c. 1000 AD . The sector , a calculating instrument used for solving problems in proportion, trigonometry , multiplication and division, and for various functions, such as squares and cube roots,
21300-414: Was its precursor. During the 9th and 10th centuries, threatened by Viking invasions , France became a decentralised state: the nobility's titles and lands became hereditary, and authority of the king became more religious than secular, and so was less effective and challenged by noblemen. Thus was established feudalism in France. Some king's vassals grew so powerful they posed a threat to the king. After
21450-477: Was made of germanium . Noyce's monolithic IC was fabricated using the planar process , developed by his colleague Jean Hoerni in early 1959. In turn, the planar process was based on Carl Frosch and Lincoln Derick work on semiconductor surface passivation by silicon dioxide. Modern monolithic ICs are predominantly MOS ( metal–oxide–semiconductor ) integrated circuits, built from MOSFETs (MOS transistors). The earliest experimental MOS IC to be fabricated
21600-521: Was most likely a form of tally stick . Later record keeping aids throughout the Fertile Crescent included calculi (clay spheres, cones, etc.) which represented counts of items, likely livestock or grains, sealed in hollow unbaked clay containers. The use of counting rods is one example. The abacus was initially used for arithmetic tasks. The Roman abacus was developed from devices used in Babylonia as early as 2400 BCE. Since then, many other forms of reckoning boards or tables have been invented. In
21750-434: Was not Turing-complete. Nine Mk II Colossi were built (The Mk I was converted to a Mk II making ten machines in total). Colossus Mark I contained 1,500 thermionic valves (tubes), but Mark II with 2,400 valves, was both five times faster and simpler to operate than Mark I, greatly speeding the decoding process. The ENIAC (Electronic Numerical Integrator and Computer) was the first electronic programmable computer built in
21900-453: Was restored with the Provisional Government of the French Republic (GPRF). This interim government, established by de Gaulle, continued to wage war against Germany and to purge collaborators from office . It made important reforms e.g. suffrage extended to women and the creation of a social security system. A new constitution resulted in the Fourth Republic (1946–1958), which saw strong economic growth ( les Trente Glorieuses ). France
22050-608: Was set to impose a carbon tax in 2009; however, the plan was abandoned due to fears of burdening French businesses. Forests account for 31 per cent of France's land area—the fourth-highest proportion in Europe—representing an increase of 7 per cent since 1990. French forests are some of the most diverse in Europe, comprising more than 140 species of trees. France had a 2018 Forest Landscape Integrity Index mean score of 4.52/10, ranking it 123rd globally. There are nine national parks and 46 natural parks in France. A regional nature park (French: parc naturel régional or PNR)
22200-404: Was unseated following defeat in the Franco-Prussian War of 1870, and his regime replaced by the Third Republic . By 1875, the French conquest of Algeria was complete, with approximately 825,000 Algerians killed from famine, disease, and violence.
