	NETWORKING Networking is a Department under the School of Computer Science. Courses focus on the interconnection of computing systems to share resources, and ultimately should provide an ever-increasing level of complexity in subject material, much as advancing classes in a traditional university do. Networking is the practice of enabling and harnessing the transmission of data from one computer system to another. A crude analogy of a data network is pictured at right: two tin cans connected by a simple string. Note that what this basic analogy suggests holds true for actual implementations of data networks: The network exists merely as a medium for communications of some kind, across it A protocol of some form is needed to initiate and carry on conversations (this is not intrinsic to the network itself) The same protocol (a spoken language) can also be used with different media for the same purpose; different networks have different advantages and uses A network may require one engineer to design it, another engineer to build it, and another engineer entirely to administer it. The skills needed for each stage in the process are related but not necessarily dependent; hence, Networking is interdisciplinary. The distinction between Networking and Computer Science in general is difficult to precisely define; it is better perhaps to consider that Networking grew out of Computer Science, because of a need to extend the existing capabilities of a computer (which includes data transmission) across large distances and with other unlike systems. However, an extensive background in Computer Science is not necessary to study or even practice Networking. A Network Engineer is a qualified individual who works with networks of some form, but the scope of that work and the skills required may be as diverse - even from one job to the next - as those of any scientist. Networking is the practice of enabling and harnessing the transmission of data from one computer system to another, and can be divided into three categories: Connectivity Concepts - The principles and methods devices use to communicate over a network Mediums - The actual, physical method used to communicate. Administration - The process of maintaining a network. TRAVEL TO NEW YORK New York is a state in the Mid-Atlantic and Northeastern regions of the United States, and is the country's third most populous state, following California and Texas. The estimated population of New York is over 20 million! It is bordered by Vermont, Massachusetts, Connecticut, New Jersey, and Pennsylvania, and shares a water border with Rhode Island as well as an international border with the Canadian provinces of Quebec and Ontario. New York's Adirondack Park is the largest state park in the United States. It is larger than the Yellowstone, Yosemite, Grand Canyon, Glacier and Olympic National Parks combined. New York established the first state park in the United States at Niagra Falls in 1885. Niagara Falls, on the Niagara River as it flows from Lake Erie to Lake Ontario, is a popular attraction. The Hudson River begins with Lake Tear of the Clouds and flows south through the eastern part of the state without draining Lakes George or Champlain. Lake George empties at its north end into Lake Champlain, whose northern end extends into Canada, where it drains into the Richelieu and then the St. Lawrence Rivers. Four of New York City's five boroughs are on the three islands at the mouth of the Hudson River: Manhattan Island, Staten Island, and Brooklyn and Queens on Long Island. New York's agricultural outputs are dairy products, cattle and other livestock, vegetables, nursery stock, and apples. Its industrial outputs are printing and publishing, scientific instruments, electric equipment, machinery, chemical products, and tourism. Canada is a very important economic partner for the state. 23% of the state's total worldwide exports went to Canada in 2004. Tourism from the north is also a large part of the economy. Canadians spent US$487 million in 2004 while visiting the state. New York City is the leading center of banking, finance and communication in the United States and is the location of the New York Stock Exchange, the largest stock exchange in the world by dollar volume. Many of the world's largest corporations are based in the city. Portions of New York's transportation system are intermodal, allowing travelers to easily switch from one mode of transportation to another. One of the most notable examples is AirTrain JFK which allows rail passengers to travel directly to terminals at John F. Kennedy International Airport.
