1Block scheduling — is a type of academic scheduling in which each student has fewer classes per day for a longer period of time. This is intended to result in more time for teaching due to less class switching and preparation. It also allows for a student to take… …
2Block 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… …

6Concatenated error correction code — In coding theory, concatenated codes form a class of error correcting codes that are derived by combining an inner code and an outer code. They were conceived in 1966 by Dave Forney as a solution to the problem of finding a code that has both… …
