block size — The largest contiguous amount of disk space allocated by the file system. Files larger than the file system s block size may be broken into smaller fragments when they are stored, with sections of the file being stored in different locations… … Dictionary of networking
Block size (cryptography) — In modern cryptography, symmetric key ciphers are generally divided into stream ciphers and block ciphers. Block ciphers operate on a fixed length string of bits. The length of this bit string is the block size. Both the input (plaintext) and… … Wikipedia
Size Strength classification — is a two parameter rock classification based on the strength of intact rock and the spacing of discontinuities in the rock mass. It was developed by Louis and Franklin (1970 75). The size strength approach to rock mass characterisation has been… … Wikipedia
Block suballocation — is a feature of some computer file systems which allows large blocks or allocation units to be used while making efficient use of slack space at the end of large files, space which would otherwise be lost for other use to internal fragmentation.… … Wikipedia

Block cipher — In cryptography, a block cipher is a symmetric key cipher operating on fixed length groups of bits, called blocks, with an unvarying transformation. A block cipher encryption algorithm might take (for example) a 128 bit block of plaintext as… … Wikipedia
Block (data storage) — In computing (specifically data transmission and data storage), block is a sequence of bytes or bits, having a nominal length (a block size ). Data thus structured is said to be blocked . The process of putting data into blocks is called blocking … Wikipedia
