A laptop (also known as a notebook) is a
personal computer designed for mobile use small enough to sit on one's lap[1]. A laptop includes most of the typical components of a typical desktop computer, including a display, a keyboard, a pointing device (a touchpad, also known as a trackpad, or a pointing stick) as well as a battery, into a single small and light unit. The rechargeable battery required is charged from an AC/DC adapter (ie, a wll wart) and typically stores enough energy to run the laptop for several hours.
Laptops are usually shaped like a large
notebook with thicknesses between 0.7–1.5 inches (18–38 mm) and dimensions ranging from 10x8 inches (27x22cm, 13" display) to 15x11 inches (39x28cm, 17" display) and up. Modern laptops weigh 3 to 12 pounds (1.4 to 5.4 kg); older laptops were usually heavier. Most laptops are designed in the flip form factor to protect the screen and the keyboard when closed. Modern 'tablet' laptops have a complex joint between the keyboard housing and the display, permitting the display panel to twist and then lay flat on the keyboard housing. They usually have a touchscreen display and some include handwriting recognition or graphics drawing capability.
Laptops were originally considered to be "a small niche market"
[2] and were thought suitable mostly for "specialized field applications" such as "the military, the Internal Revenue Service, accountants and sales representatives".[2][3] Battery-powered portable computers had just 2% worldwide market share in 1986[4]. But today, there are already more laptops than desktops in businesses, and laptop are becoming obligatory for student use and more popular for general use.[5] According to a forecast by Intel, more laptops than desktops will be sold in the general PC market as soon as 2009[6

Internet

The Internet is a global system of interconnected computer networks that interchange data by packet switching using the standardized Internet Protocol Suite (TCP/IP). It is a "network of networks" that consists of millions of private and public, academic, business, and government networks of local to global scope that are linked by copper wires, fiber-optic cables, wireless connections, and other technologies.The Internet carries various information resources and services, such as electronic mail, online chat, file transfer and file sharing, online gaming, and the inter-linked hypertext documents and other resources of the World Wide Web (WWW).
Terminology:
The terms Internet and World Wide Web are often used in every-day speech without much distinction. However, the Internet and the World Wide Web are not one and the same. The Internet is a global data communications system. It is a hardware and software infrastructure that provides connectivity between computers. In contrast, the Web is one of the services communicated via the Internet. It is a collection of interconnected documents and other resources, linked by hyperlinks and URLs.[1]The term internet is written both with capital and without capital, and is used both with and without the definite article.
Today's Internet:
Aside from the complex physical connections that make up its infrastructure, the Internet is facilitated by bi- or multi-lateral commercial contracts (e.g., peering agreements), and by technical specifications or protocols that describe how to exchange data over the network. Indeed, the Internet is defined by its interconnections and routing policies.As of June 30, 2008, 1.463 billion people use the Internet according to Internet World Stats.

Blue City, Oman

The Blue City is a $15 billion megacity project started by the Oman. The Blue City project will take up roughly 34 square kilometers along the coastal region at Al Sawaadi, only 45 minutes from Muscat. When completed, the city will include 16 hotels, two hospitals, a large university.. Also, there will be an aquarium, a convention center and a sports village which will be hosting a lot of European and international football teams for the pre-season. The chairman of the Blue City, Anees Issa, plans to announce in 2006 with the association of one of the top football club in Europe and one of the celebrity players. Only the 500,000 resident Dubai Waterfront project is bigger.
About the Blue City:
Located on a natural peninsula 30 minutes from Muscat Seeb Airport, The Blue City is a 32 square kilometer (12.36 square mile) waterfront city being built along 16 kilometers (9.95 miles) of shoreline adjacent to the Gulf of Oman.One of the largest scale developments in the Middle East, the Blue City represents a total investment of between $15 - $20 billion. The first round of financing was secured through the issuing of a bond note by Bear Stearns on international markets raising $925 million US. The note was rated Baa3 by ratings agency Moody’s in March, 2007, following on from a BBB- rating by Fitch when the note was issued. Bear Stearns was subsequently awarded “Middle East Leisure Deal of the Year 2006” by Project Finance for the arranging of the Blue City note.The organization behind the project is Al Sawadi Investment & Tourism Company (ASIT) which has the endorsement of the government of Oman to bring this massive urban development to life. Blue City will serve as a growth engine for the Omani economy and will radically expand the tourism facilities in Oman.The city will generate large scale employment opportunities for Omani nationals, promote freehold property ownership for nationals and expatriates alike and serve as a hub for leisure activities in the sultanate.
Creating Jobs:
Blue City will also be creating thousands of jobs. The first phase alone is expected to create 7,000 direct jobs and 25,000 indirect jobs."This is why we came into creating this urban economy, to create jobs. We thought about things that the country needs, so we went into hotels, shopping, entertainment, amusement parks, theatres and bowling. Furthermore, we will have one of the top universities from the United States, not an affiliation, but a real university," Mr. Issa was quoted in the December 15, 2005 edition of Our World, a USA Today insert.The Blue City chairman is also negotiating with two international hospitals for cancer and heart treatment. "Again this will attract people from the Middle East or Africa to come and be treated here and that will create jobs for nurses, hotels and many other opportunities. This is how we create the economy and this is why the government liked the idea. The Blue City is a tourist project that we converted into a macro-economy."

Police



Police are agents or agencies, usually of the executive, empowered to enforce the law and to ensure public and social order through the legitimized use of force.The term is most commonly associated with police departments of a state that are authorized to exercise the police power of that state within a defined legal or territorial area of responsibility. The word comes via French from the Latin politia (“civil administration”), which itself derives from the Ancient Greek πόλις, for polis ("city").
Overview:
The first police force comparable to present-day police was established in 1667 under King Louis XIV in France, although modern police usually trace their origins to the 1800 establishment of the Marine Police in London, the Glasgow Police, and the Napoleonic police of Paris.[2][3][4] The first modern police force is also commonly said to be the London Metropolitan Police, established in 1829, which promoted the preventive role of police as a deterrent to urban crime and disorder.[5]Law enforcement however constitutes only part of policing activity.[6] Policing has included an array of activities in different situations, but the predominant ones are concerned with the preservation of order.[7] In some societies, in the late 18th century and early 19th century, these developed within the context of maintaining the class system and the protection of private property.[8]Alternative names for police force include constabulary, gendarmerie, police department, police service, crime prevention, protective services, law enforcement agency or Garda Síochána, and members can be police officers, troopers, sheriffs, constables, rangers, peace officers or Garda. Russian police and police of the Soviet-era Eastern Europe are (or were) called militsiya.
