Intelligence Forum
Intelligence has been defined in many ways: the capacity for abstraction, logic, understanding, self-awareness, learning, emotional knowledge, reasoning, planning, creativity, critical thinking, and problem-solving. More generally, it can be described as the ability to perceive or infer information, and to retain it as knowledge to be applied towards adaptive behaviors within an environment or context. Intelligence is most often studied in humans but has also been observed in both non-human animals and in plant intelligence, plants despite controversy as to whether some of these forms of life exhibit intelligence. Intelligence in computers or other machines is called artificial intelligence. Etymology The word ''wikt:intelligence#English, intelligence'' derives from the Latin nouns ''wikt:intelligentia, intelligentia'' or ''wikt:intellectus, intellēctus'', which in turn stem from the verb ''wikt:intelligere, intelligere'', to comprehend or perceive. In the Middle Ages, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Democratic Republic Of Georgia
The Democratic Republic of Georgia (DRG; ka, საქართველოს დემოკრატიული რესპუბლიკა ') was the first modern establishment of a republic of Georgia, which existed from May 1918 to February 1921. Recognized by all major European powers of the time, DRG was created in the wake of the Russian Revolution of 1917, which led to the collapse of the Russian Empire and allowed territories formerly under Saint Petersburg's rule to assert independence. In contrast to Bolshevik Russia, DRG was governed by a moderate, multi-party political system led by the Georgian Social Democratic Party ( Menshevik). Initially, DRG was a protectorate of the German Empire. However, after the German defeat in World War I, the country was partially occupied by British troops, who were sent there to counter a proposed Bolshevik invasion. The British had to leave in 1920 because of the Treaty of Moscow, in which Russia recognized Georgia's inde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Government Code And Cypher School
Government Communications Headquarters, commonly known as GCHQ, is an intelligence and security organisation responsible for providing signals intelligence (SIGINT) and information assurance (IA) to the government and armed forces of the United Kingdom. Primarily based at "The Doughnut" in the suburbs of Cheltenham, GCHQ is the responsibility of the country's Secretary of State for Foreign and Commonwealth Affairs (Foreign Secretary), but it is not a part of the Foreign Office and its Director ranks as a Permanent Secretary. GCHQ was originally established after the First World War as the Government Code and Cypher School (GC&CS) and was known under that name until 1946. During the Second World War it was located at Bletchley Park, where it was responsible for breaking the German Enigma codes. There are two main components of the GCHQ, the Composite Signals Organisation (CSO), which is responsible for gathering information, and the National Cyber Security Centre (NCSC), whic ...

Room 40
Room 40, also known as 40 O.B. (old building; officially part of NID25), was the cryptanalysis section of the British Admiralty during the First World War. The group, which was formed in October 1914, began when Rear-Admiral Henry Oliver, the Director of Naval Intelligence, gave intercepts from the German radio station at Nauen, near Berlin, to Director of Naval Education Alfred Ewing, who constructed ciphers as a hobby. Ewing recruited civilians such as William Montgomery, a translator of theological works from German, and Nigel de Grey, a publisher. It was estimated that during the war Room 40 decrypted around 15,000 intercepted German communications from wireless and telegraph traffic. Most notably the section intercepted and decoded the Zimmermann Telegram, a secret diplomatic communication issued from the German Foreign Office in January 1917 that proposed a military alliance between Germany and Mexico. Its decoding has been described as the most significant intelligence ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Russian Revolution Of 1917
The Russian Revolution was a period of political and social revolution that took place in the former Russian Empire which began during the First World War. This period saw Russia abolish its monarchy and adopt a socialist form of government following two successive revolutions and a bloody civil war. The Russian Revolution can also be seen as the precursor for the other European revolutions that occurred during or in the aftermath of WWI, such as the German Revolution of 1918. The Russian Revolution was inaugurated with the February Revolution in 1917. This first revolt focused in and around the then-capital Petrograd (now Saint Petersburg). After major military losses during the war, the Russian Army had begun to mutiny. Army leaders and high ranking officials were convinced that if Tsar Nicholas II abdicated, the domestic unrest would subside. Nicholas agreed and stepped down, ushering in a new government led by the Russian Duma (parliament) which became the Russian Prov ...
