The Internet is a global system of interconnected computer networks that use the standard Internet Protocol Suite (TCP/IP) to serve billions of users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks of local to global scope that are linked by a broad array of electronic and optical networking technologies...

Mobile homes (in the United States; also called trailers or house trailers) or static caravans (in other countries; also called caravans) are prefabricated homes built in factories, rather than on site, and then taken to the place where they will be occupied. Being built on a permanently attached chassis with highway-grade wheels and tires, they are usually transported by being pulled behind a tractor-trailer over public roads to a home site...

Aircraft are vehicles which are able to fly by being supported by the air, or in general, the atmosphere of a planet. An aircraft counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Although rockets and missiles also travel through the atmosphere, most are not considered aircraft because they use rocket thrust instead of aerodynamics as the primary means of lift...

A roof is the covering on the uppermost part of a building. A roof protects the building and its contents from the effects of weather. Structures that require roofs range from a letter box to a cathedral or stadium, dwellings being the most numerous. In most countries a roof protects primarily against rain. Depending upon the nature of the building, the roof may also protect against heat, sunlight, cold, snow and wind...

An amateur (French amateur "lover of", from Old French and ultimately from Latin amatorem nom. amator, "lover") is generally considered a person attached to a particular pursuit, study, or science, without pay and often without formal training. Amateurism can be seen in both a negative and positive light. Since amateurs often do not have formal training, some amateur work may be sub-par...

Ice is water frozen into the solid state. Usually ice is the phase known as ice Ih, which is the most abundant of the varying solid phases on the Earth's surface. It can appear transparent or opaque bluish-white color, depending on the presence of impurities or air inclusions. The addition of other materials such as soil may further alter the appearance. The most common phase transition to ice Ih occurs when liquid water is cooled below 0°C (273.15K, 32°F) at standard atmospheric pressure...

Creativity is the ability to improve, where by through improvement value is added. What counts as "improved" may be in reference to the individual creator, or to the society or domain within which the innovation occurs. What counts as "valuable" is similarly defined in a variety of ways, but usually through its comparative uniqueness...
