“block”的概念、定义、翻译、参考文献-科学参考

block

Statistics

In the context of experimental design, a homogeneous group of experimental units.

Chemistry

See periodic table.

Computer

1. A collection of data units such as words, characters, or records (generally more than a single word) that are stored in adjacent physical positions in memory or on a peripheral storage device. A block can therefore be treated as a single unit whereby data can be (and usually is) transferred between storage device and memory, using one instruction. Blocks may be fixed or variable in size.
2. In coding theory, an ordered set of symbols, usually of a fixed length. The term is generally synonymous with word or string, but with the implication of fixed length.
3. See block-structured languages.
4. In parallel programming, to prevent further execution of one sequence of instructions until another sequence has done whatever is necessary to unblock it. See also blocked process.

Internet

A collection of data that is transmitted through a network as a single unit.

Electronics and Electrical Engineering

A sequence of bytes of a known (often fixed) length in a data storage device. For many devices such as hard disks or NAND flash devices, it is more efficient to transfer data in blocks of a certain size, rather than one byte at a time.

Geography

1 A section of the Earth’s crust, bounded by faults, that may be tectonically disrupted to form basins and block mountains or complex systems of troughs and ridges. The formation of a tilt-block may result in tectonic deformation along plate margins; see Agarwal and Sharma (2011) Zeitschrift. Geom. 55, 2, 194.
2 A generally angular boulder formed by frost-shattering in situ on a bedrock surface.
