Greek , eikon, "image") is an image, picture, or representation; it is a sign or likeness that stands for an object by signifying or representing it, or by analogy, as in semiotics; in computers an icon is a symbol on the monitor used to signify a command; by extension, icon is also used, particularly in modern popular culture, in the general sense of symbol — i.e. a name, face, picture or even a person readily recognized as having some well-known significance or embodying certain qualities.

>"Cart" may also mean cartridge. "CART" may mean Championship Auto Racing Teams or Center for Advanced Research and Technology. A cart is a vehicle or device using, usually, two wheels for transport. A dray is a heavy transport version of a cart, usually with four wheels. Hand-carts pushed by humans have been used around the world. In the 19th century, for instance, some Mormons travelling across the plains of the USA between 1857 and 1865 used handcarts. Perhaps the most common example today is the shopping cart (British English: shopping trolley), which has also come to have a metaphorical meaning in relation to online purchases (here, British English uses the metaphor of the shopping basket). Shopping carts first made their appearance in Oklahoma City in 1937. See more at Wikipedia.org...
