Computers Designed In Brazil
A computer is a machine that can be programmed to carry out sequences of arithmetic or logical operations (computation) automatically. Modern digital electronic computers can perform generic sets of operations known as programs. These programs enable computers to perform a wide range of tasks. A computer system is a nominally complete computer that includes the hardware, operating system (main software), and peripheral equipment needed and used for full operation. This term may also refer to a group of computers that are linked and function together, such as a computer network or computer cluster. A broad range of industrial and consumer products use computers as control systems. Simple special-purpose devices like microwave ovens and remote controls are included, as are factory devices like industrial robots and computer-aided design, as well as general-purpose devices like personal computers and mobile devices like smartphones. Computers power the Internet, which links bill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Goods Manufactured In Brazil
In economics, goods are items that satisfy human wants and provide utility, for example, to a consumer making a purchase of a satisfying product.

Private goods are things owned by people, such as televisions, living room furniture, wallets, cellular telephones, almost anything owned or used on a daily basis that is not food-related. A consumer good or "final good" is any item that is ultimately consumed, rather than used in the production of another good. For example, a microwave oven or a bicycle that is sold to a consumer is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
