Edit Watch this page Read in another language Terabyte The terabyte is a multiple of the unit byte for digital information . The prefix tera represents the fourth power of 1000, and means 10 12 in the International System of Units (SI), and therefore one terabyte is one trillion ( short scale ) bytes. The unit symbol for the terabyte is TB . Definition Edit 1 TB = 1 000 000 000 000 bytes = 10 12 bytes = 1 000 gigabytes . A related unit, the tebibyte (TiB), using a binary prefix , is equal to 1024 4 bytes. One terabyte is about 0.9095 TiB. Despite the introduction of these standardized binary prefixes, the terabyte is still also commonly used in some computer operating systems , primarily Microsoft Windows , to denote 1 099 511 627 776 (1024 4 or 2 40 ) bytes for disk drive capacity.

A multi-core processor is a single computing component with two or more independent processing units called cores, which read and execute program instructions . [1] The instructions are ordinary CPU instructions (such as add, move data, and branch) but the single processor can run multiple instructions on separate cores at the same time, increasing overall speed for programs amenable to parallel computing . [2] Manufacturers typically integrate the cores onto a single integrated circuit die (known as a...

A windmill is a mill that converts the energy of wind into rotational energy by means of vanes called sails or blades. [1] [2] Centuries ago, windmills usually were used to mill grain ( gristmills ), pump water ( windpumps ), or both. [3] The majority of modern windmills take the form of wind turbines used to generate electricity, or windpumps used to pump water, either for land drainage or to extract groundwater . Windmills in antiquity Edit Heron 's wind-powered organ . The windwheel of the Greek engineer Heron of Alexandria in the first century is the earliest known instance of using a wind-driven wheel to power a machine. [4] [5] Ano...
