The Amazon rainforest (Portuguese: Floresta Amazônica or Amazônia; Spanish: Selva Amazónica, Amazonía or usually Amazonia; French: Forêt amazonienne; Dutch: Amazoneregenwoud), also known in English as Amazonia or theAmazon Jungle, is a moist broadleaf forest that covers most of the Amazon Basin of South America. This basin encompasses 7,000,000 square kilometres (2,700,000 sq mi), of which 5,500,000 square kilometres (2,100,000 sq mi) are covered by the rainforest. This region includes territory belonging to nine nations. The majority of the forest is contained within Brazil, with 60% of the rainforest, followed by Peru with 13%, Colombia with 10%, and with minor amounts in Venezuela, Ecuador, Bolivia, Guyana, Suriname and French Guiana. States or departments in four nations contain "Amazonas" in their names. The Amazon represents over half of the planet's remaining rainforests, and comprises the largest and most biodiverse tract of tropical rainforest in the world, with an estimated 390 billion individual trees divided into 16,000 species.




Mount Rushmore


Mount Rushmore

      The Mount Rushmore National Memorial is a sculpture carved into the granite face of Mount Rushmore (Lakota Sioux name: Six Grandfathers) near Keystone, South Dakota, in the United States. Sculpted by Danish-AmericanGutzon Borglum and his son, Lincoln Borglum, Mount Rushmore features 60-foot (18 m) sculptures of the heads of four United States presidents: George Washington (1732–1799), Thomas Jefferson (1743–1826), Theodore Roosevelt (1858–1919), and Abraham Lincoln (1809–1865).The entire memorial covers 1,278.45 acres (5.17 km2) and is 5,725 feet (1,745 m) above sea level.
South Dakota historian Doane Robinson is credited with conceiving the idea of carving the likenesses of famous people into the Black Hills region of South Dakota in order to promote tourism in the region. Robinson's initial idea was to sculpt the Needles; however, Gutzon Borglum rejected the Needles site because of the poor quality of the granite and strong opposition from Native American groups. They settled on the Mount Rushmore location, which also has the advantage of facing southeast for maximum sun exposure. Robinson wanted it to feature westernheroes like Lewis and Clark, Red Cloud,[5] and Buffalo Bill Cody,[6] but Borglum decided the sculpture should have a more national focus and chose the four presidents whose likenesses would be carved into the mountain. After securing federal funding through the enthusiastic sponsorship of "Mount Rushmore's great political patron", U.S. Senator Peter Norbeck,construction on the memorial began in 1927, and the presidents' faces were completed between 1934 and 1939. Upon Gutzon Borglum's death in March 1941, his son Lincoln Borglum took over construction. Although the initial concept called for each president to be depicted from head to waist, lack of funding forced construction to end in late October 1941.
Mount Rushmore has become an iconic symbol of presidential greatness and has appeared in works of fiction, and has been discussed or depicted in other popular works. It attracts over two million people annually

Computer Network

Computer Network



Definition - What does Computer Network mean?
       A computer network is a group of computer systems and other computing hardware devices that are linked together through communication channels to facilitate communication and resource-sharing among a wide range of users. Networks are commonly categorized based on their characteristics.




Local Area Network (LAN)

Definition - What does Local Area Network (LAN) mean?
       A local area network (LAN) is a computer network within a small geographical area such as a home, school, computer laboratory, office building or group of buildings.
       A LAN is composed of inter-connected workstations and personal computers which are each capable of accessing and sharing data and devices, such as printers, scanners and data storage devices, anywhere on the LAN. LANs are characterized by higher communication and data transfer rates and the lack of any need for leased communication lines.



Metropolitan Area Network (MAN)

Definition - What does Metropolitan Area Network (MAN) mean?
       A metropolitan area network (MAN) is similar to a local area network (LAN) but spans an entire city or campus. MANs are formed by connecting multiple LANs. Thus, MANs are larger than LANs but smaller than wide area networks (WAN). 
       MANs are extremely efficient and provide fast communication via high-speed carriers, such as fiber optic cables.




Wide Area Network (WAN)

Definition - What does Wide Area Network (WAN) mean?
       A wide area network (WAN) is a network that exists over a large-scale geographical area. A WAN connects different smaller networks, including local area networks (LAN) and metro area networks (MAN). This ensures that computers and users in one location can communicate with computers and users in other locations. WAN implementation can be done either with the help of the public transmission system or a private network.



Network Topology

Definition - What does Network Topology mean?
       Network topology is the interconnected pattern of network elements. A network topology may be physical, mapping hardware configuration, or logical, mapping the path that the data must take in order to travel around the network.
       There are many identified topologies but they are not strict, which means that any of them can be combined. However, each topology has a different standard and may use different hardware methods so they are not interchangeable.

Google's office
       Google has been founded in California in January 1996 as a research project by Larry Page and Sergey Brin when they were both studying in graduate school at Stanford University. 15 years later, Google is one of the most recognizable brands in the world.The company manages more than one million servers in data centers (DC) around the world, and processes over one billion search requests and twenty-four petabytes of user data each day, bringing incredible profits to its owners. Part of this income is invested in creating the most comfortable and pleasant working environment, which each employee can only dream of.
These are places in Google's office.

Google X

       As you know, Google - is not only a search engine: The company is a world leader in the creation of gadgets, internet services, and more. The most curious development team is engaged in a secret Google X, and among their projects - here are 10 ideas that the Internet giant seeks to bring to life.
                                

1. Car without a driver will make road traffic safer.
       Experts of Google X for several years working on the project Driverless Car Program. 
Negotiations are underway with the authorities for permission to test the self-governing vehicles on public roads - as long as this agreement only states of California and Nevada.
 
       A fleet of ten vehicles with test systems allow run over more than 480 thousand km (as of August of 2012), and of course, tests are continuing. However, it is unclear when such a system will be commercially available.



2. Google Glass will change the way you think about gadgets.
       Having put on those glasses, you can forget about the screens of smartphones and computers - the right information will always be available in only one eye movements. 
       One way to look up - and before you calendar, email, social networks, weather, in general, everything that you want. 
       Google Glass makes a revolutionary technology available to a wide range of people so far only a few lucky people, mostly developers and journalists were able to get a working prototype of points, but the consumers opportunity arises next year.

 
3. "Smart House" according to Google.
        The technology, called Android @ Home, will fully automate all of the life support system by connecting to the Internet, for example, while you are not home, a refrigerator will be able to order the necessary products itself, and coffee maker to make coffee exactly to your arrival. 
        Android @ Home will connect all electrical appliances.

 
4. Space elevator
       According to published in the journal «Time» information Google X team in 2011, the year included the idea of ​​a "space elevator" in the so-called list of "What if ...". I must say, the very concept of this method of delivery to the orbit of people and goods put forward by K. Tsiolkovsky in 1895, the year. 
       Do not wait for Google's early implementation of this idea - the development of "lift into orbit," presents many technical challenges, and all the more likely to say that to implement this idea in life is impossible. However, it's probably Google thus "cover their tracks" to save the process of developing a secret.



                               


5. Watch a smartphone based on Android.
       Recently, it was reported that Google is preparing a direct competitor iWatch from Apple - a watch, combined with the smartphone: of course, watches SmartWatch smartphone from Google will use the operating system Android. 
       This latest «must have»-new to the gadget lovers will be available early next year.







6. Google will take care of your health.
       The Internet giant has a stake in the company Adimab, engaged in the development of diagnostics and treatment of various diseases, which would bring a variety of technologies and methods to combat diseases.The revolutionary idea is the invention of miniature sensors involved in the search and optimization of antibodies produced by the body - to start treatment only need to swallow such a sensor. 
       Another development in the field of Google Health is a subsidiary of iPierian, creating the technology of "cellular reprogramming» (cellular reprogramming), which will fight the disease by modifying cells.



7. Internet airships cover the entire planet wireless.
       Google's ambitions as a provider of Internet reached all-time highs - the company is developing airships that will provide wireless connectivity the entire planet, including remote regions in Africa and other parts of the Earth. 
       If the project is realized, the "world wide web" will get about another 1 billion people - mostly residents of the "third world."



8. Game console based on Android.
       The popularity of the Android platform is growing all over the world, and Google is seeking to use its potential to the maximum. 
       «Wall Street Journal» spoke about the development of the gaming console from Google, which is designed to be a "killer" similar technology "Yabloko» - Apple TV: game console from Google allows you to run any Android-games directly on your home television.



9. The way Google determines the development of smart phones Motorola.
       Buy Google of Motorola Mobility (transaction was $ 12.5 billion) to become the owner of the first allowed 24.5 thousand patents and designs. 
       Under the wing of the Internet giant will release a smartphone Motorola Moto X based on Android, which has all the modern features and characteristics, as well as, of course, a number of trendy "chips", which has no rivals - release date already quite close.



                              

10. Eco-friendly sources of energy
       The company Makani Power - developer of advanced technologies in the use of wind and solar energy: Google previously invested in the company a lot of money, and recently acquired in its entirety and included in the project, which deals with Google X. 
       The best-known development Makani Power - wind turbines, hovering at an altitude of almost 300 m to 650 m-minute and allow to generate electricity out of thin air.
