Postal Telephone And Telegraph
A postal, telegraph, and telephone service (or PTT) is a government agency responsible for postal mail, telegraph, and telephone services. Such monopolies existed in many countries, though not in North America or Japan. Many PTTs have been partially or completely privatised in recent years. In some of these privatisations, the PTT was renamed completely (such as KPN in the Netherlands, Orange S.A. in France, BT Group in the United Kingdom, Swisscom in Switzerland, Telstra in Australia, Spark in New Zealand, Chunghwa Telecom in Taiwan, A1 Telekom Austria Group in Austria, TDC Group in Denmark, Telia Company in Sweden and Finland, Telenor in Norway, Singtel in Singapore and Síminn in Iceland), whereas in others, the name of the privatised corporation has been only slightly modified, such as PT Telkom in Indonesia, Deutsche Telekom in Germany, Kosovo Telecom in Kosovo, Telekom Malaysia in Malaysia and Post Luxembourg in Luxembourg. Monopoly service In countries that had a PTT unit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1987 Stock Market Crash
Black Monday is the name commonly given to the global, sudden, severe, and largely unexpected stock market crash on Monday, October 19, 1987. In Australia and New Zealand, the day is also referred to as ''Black Tuesday'' because of the time zone difference from other English-speaking countries. All of the twenty-three major world markets experienced a sharp decline in October 1987. When measured in United States dollars, eight markets declined by 20 to 29%, three by 30 to 39% (Malaysia, Mexico and New Zealand), and three by more than 40% (Hong Kong, Australia and Singapore). The least affected was Austria (a fall of 11.4%) while the most affected was Hong Kong with a drop of 45.8%. Out of twenty-three major industrial countries, nineteen had a decline greater than 20%. Worldwide losses were estimated at US$1.71 trillion. The severity of the crash sparked fears of extended economic instability or even a reprise of the Great Depression. The degree to which the stock market cras ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wide Area Network
A wide area network (WAN) is a telecommunications network that extends over a large geographic area. Wide area networks are often established with leased telecommunication circuits. Businesses, as well as schools and government entities, use wide area networks to relay data to staff, students, clients, buyers and suppliers from various locations around the world. In essence, this mode of telecommunication allows a business to effectively carry out its daily function regardless of location. The Internet may be considered a WAN. Design options The textbook definition of a WAN is a computer network spanning regions, countries, or even the world. However, in terms of the application of communication protocols and concepts, it may be best to view WANs as computer networking technologies used to transmit data over long distances, and between different networks. This distinction stems from the fact that common local area network (LAN) technologies operating at lower layers of the O ...

Local Area Network
A local area network (LAN) is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building. By contrast, a wide area network (WAN) not only covers a larger geographic distance, but also generally involves leased telecommunication circuits. Ethernet and Wi-Fi are the two most common technologies in use for local area networks. Historical network technologies include ARCNET, Token Ring and AppleTalk. History The increasing demand and usage of computers in universities and research labs in the late 1960s generated the need to provide high-speed interconnections between computer systems. A 1970 report from the Lawrence Radiation Laboratory detailing the growth of their "Octopus" network gave a good indication of the situation. A number of experimental and early commercial LAN technologies were developed in the 1970s. Cambridge Ring was developed at Cambridge University starting in 1974. Ethe ...

Packet-switched Network
In telecommunications, packet switching is a method of grouping data into '' packets'' that are transmitted over a digital network. Packets are made of a header and a payload. Data in the header is used by networking hardware to direct the packet to its destination, where the payload is extracted and used by an operating system, application software, or higher layer protocols. Packet switching is the primary basis for data communications in computer networks worldwide. In the early 1960s, American computer scientist Paul Baran developed the concept that he called "distributed adaptive message block switching", with the goal of providing a fault-tolerant, efficient routing method for telecommunication messages as part of a research program at the RAND Corporation, funded by the United States Department of Defense. His ideas contradicted then-established principles of pre-allocation of network bandwidth, exemplified by the development of telecommunications in the Bell System. The ...
