Adobe is a natural building material made from sand, clay, and water, with some kind of fibrous or organic material.Adobe structures are extremely durable and account for some of the oldest extant buildings on the planet. In hot climates, compared to wooden buildings, adobe buildings offer significant advantages due to their greater thermal mass, but they are known to be particularly susceptible to seismic damage in an event such as an earthquake.Buildings made of sun-dried earth are common in the Middle East, North Africa, South America, southwestern North America, and in Spain.A distinction is sometimes made between the smaller adobes, which are about the size of ordinary baked bricks, and the larger adobines, some of which are as much as from one to two yards (2 m) long.An adobe brick is a composite material made of clay mixed with water and an organic material such as straw or dung. The soil composition typically contains clay and sand. Straw is useful in binding the brick together and allowing the brick to dry evenly. Dung offers the same advantage and is also added to repel insects.The mixture is roughly half sand (50%), one-third clay (35%), and one-sixth straw (15%).
Adobe Systems Incorporated ( ) is an American computer software company headquartered in San Jose, California, USA.Adobe was founded in December 1982 by John Warnock and Charles Geschke, who established the company after leaving Xerox PARC in order to develop and sell the PostScript page description language.
