The Impact Of Computers THE IMPACT OF COMPUTERS Computer technology not only has solved problems but also has created some, including a certain amount of culture shock as individuals attempt to deal with the new technology. A major role of computer science has been to alleviate such problems, mainly by making computer systems cheaper, faster, more reliable, easier to use. Computers are forever present in the workplace. Word processors-computer software packages that simplify the creational and modification of documents-have largely replaced the typewriter. Electronic mail has made it easy to send messages worldwide via computer communication networks. Office automation has become the term for linking workstations, printers, database system, and other tools by means of a local-area network. An eventual goal of office automation has been termed the ?paperless office.? Although such changes ultimately make office work much more efficient, they have not been without cost in terms of purchasing and frequently upgrading the necessary hardware and software and of training workers to use the new technology. Computer integrated manufacturing is a relatively new technology arising from the application of many computer science sub disciplines to support the manufacturing enterprise. The technology of CIM emphasizes that all aspects of manufacturing should be not only computerized as much as possible but also linked together via a computer communication network into an integrated whole. In short, CIM has the potential to enable manufacturers to build cheaper, higher-quality products and thus improve their competitiveness. Making a telephone call no longer should conjure up visions of operators connecting cables by hand or even of electrical signals causing relays to click into place and effect connections during dialing. The telephone system now is just a multilevel computer network with software switches in the network nodes to route calls get through much more quickly and reliably than they did in the past. A disadvantage is the potential for dramatic and widespread failures; for as has happened. The downside of this technology is the potential for security problems. Intruders can see packets traveling on a network and can perhaps interpret them to obtain confidential information. Computer technology has had a significant impact on retail stores. All but the smallest shops have replaced the old-fashioned cash register with a terminal linked to a computer system. The terminal may require that the clerk type in the code for the item; but more and more frequently the checkout counter include a bar-code scanner, a device that directly reads into the computer the UPC printed on each package. Cash-register receipts can then include brief descriptions of the items purchased, and the purchase information is also relayed back to the computer to cause and immediate adjustment in the inventory data. The inventory system can easily alert the manager when the supply of some item drops below a specified threshold. In the case of retail chains linked by networks, the order for a new supply of an item may be automatically generated and sent electronically to the supply warehouse. In a less extensively automated arrangement, the manager can send in the order electronically by a dial-up link to the supplier's computer. These developments have made shopping much more convenient. The checkout process is faster; checkout lines shorter; and the desired item are more likely to be in stock. Computer technology has been incorporated into automobiles. Computers are involved (CAD systems) not only the design of cars but also in the manufacturing and testing process, perhaps making use of CIM technology. Today's automobiles themselves include numerous computer chips that analyze sensor data and alert the driver to actual and potential malfunctions. Although increased reliability has been achieved by implementing such computerization, a drawback is that only automotive repair shops with a large investment in high-tech interfaces and diagnostic tools for these computerized systems can handle any but the simplest repairs

Bahrain Geography, History, Culture, Economy

Bahrain Geography, History, Culture, Economy Population: 738,004 (July 2010 estimate)Capital: ManamaArea: 293 square miles (760 sq km)Coastline: 100 miles (161 km)Highest Point: Jabal ad Dukhan at 400 feet (122 m)Bahrain is a small country located in the Persian Gulf. It is considered a part of the Middle East and it is an archipelago that is made up of 33 islands. The largest island of Bahrain is Bahrain Island and as such it is where most of the countrys population and economy is based. Like many other Middle Eastern nations, Bahrain has recently been in the news due to increasing social unrest and violent anti-government protests. History of Bahrain Bahrain has a long history that dates back to at least 5,000 years ago, at which time the region served as a trading center between Mesopotamia and the Indus Valley. The civilization living in Bahrain at that time was the Dilmun civilization, however, when trade with India declined around 2,000 B.C.E, so too did their civilization. In 600 B.C.E, the region became a part of the Babylonian Empire. According to the U.S. Department of State, little is known about Bahrains history from this time until the arrival of Alexander the Great  in the 4th century B.C.E.During its early years, Bahrain was known as Tylos until the 7th century when it became an Islamic nation. Bahrain was then controlled by various forces until 1783 when the Al Khalifa family took control of the region from Persia.In the 1830s, Bahrain became a British Protectorate after the Al Khalifa family signed a treaty with the United Kingdom which guaranteed British protection in the event of a military conflict with Ottoma n Turkey. In 1935, Britain established its main military base in the Persian Gulf in Bahrain but in 1968, Britain announced the end of the treaty with Bahrain and other Persian Gulf sheikdoms. As a result, Bahrain joined the eight other sheikdoms to form a union of Arab emirates. However, by 1971, they had not officially unified and Bahrain declared itself independent on August 15, 1971.In 1973, Bahrain elected its first parliament and drafted a constitution but in 1975 the parliament was broken up when it tried to remove power from the Al Khalifa family which still forms the executive branch of Bahrains government. In the 1990s, Bahrain experienced some political instability and violence from the Shia majority and as a result, the government cabinet underwent some changes. These changes initially ended the violence but in 1996 several hotels and restaurants were bombed and the country has been unstable off and on since then. Government of Bahrain Today Bahrains government is considered a constitutional monarchy and it has a chief of state (the countrys king) and a prime minister for its executive branch. It also has a bicameral legislature that is made up of the Consultative Council and the Council of Representatives. Bahrains judicial branch consists of its High Civil Appeals Court. The country is divided into five governorates (Asamah, Janubiyah, Muharraq, Shamaliyah, and Wasat) that is administered by an appointed governor. Economics and Land Use in Bahrain Bahrain has a diversified economy with many multinational firms. A large part of Bahrains economy depends on oil and petroleum production, however. Other industries in Bahrain include aluminum smelting, iron pelletization, fertilizer production, Islamic and offshore banking, insurance, ship repairing and tourism. Agriculture only represents about one percent of Bahrains economy but the main products are fruit, vegetables, poultry, dairy products, shrimp, and fish. Geography and Climate of Bahrain Bahrain is located in the Middle Easts Persian Gulf to the east of Saudi Arabia. It is a small nation with a total area of just 293 square miles (760 sq km) spread out over many different small islands. Bahrain has a relatively flat topography consisting of desert plain. The central part of Bahrains main island has a low elevation escarpment and the highest point in the country is Jabal ad Dukhan at 400 feet (122 m). The climate of Bahrain is arid and as such it has mild winters and very hot, humid summers. The countrys capital and largest city, Manama, has an average January low temperature of 57ËšF (14ËšC) and an average August high temperature of 100ËšF (38ËšC).​ References Central Intelligence Agency.
