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 size — can refer to: *Block (data storage), the size of a block in data storage and file systems. *Block size (cryptography), the minimal unit of data for block ciphers. *Block size (mathematics) … Wikipedia
Block Truncation Coding — Block Truncation Coding, or BTC, is a type of lossy image compression technique for greyscale images. It divides the original images into blocks and then uses a quantiser to reduce the number of grey levels in each block whilst maintaining the… … Wikipedia

Block cipher modes of operation — This article is about cryptography. For method of operating , see modus operandi. In cryptography, modes of operation is the procedure of enabling the repeated and secure use of a block cipher under a single key.[1][2] A block cipher by itself… … 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
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
Block quotation — A block quotation, also known as a long quotation , block quote or extract , is a quotation in a written document, set off from the main text as a distinct paragraph or block. It is typically used for a longer passage than a run in quotation,… … Wikipedia
