  2. Data deduplication - Wikipedia

    en.wikipedia.org/wiki/Data_deduplication

    Whenever a match occurs, the redundant chunk is replaced with a small reference that points to the stored chunk. Given that the same byte pattern may occur dozens, hundreds, or even thousands of times (the match frequency is dependent on the chunk size), the amount of data that must be stored or transferred can be greatly reduced.

    If, for example, the output is constrained to 32-bit integer values, then the hash values can be used to index into an array. Such hashing is commonly used to accelerate data searches. [10] Producing fixed-length output from variable-length input can be accomplished by breaking the input data into chunks of specific size.

    A memory address a is said to be n-byte aligned when a is a multiple of n (where n is a power of 2). In this context, a byte is the smallest unit of memory access, i.e. each memory address specifies a different byte.

  5. Chunking (psychology) - Wikipedia

    en.wikipedia.org/wiki/Chunking_(psychology)

    A modality effect is present in chunking. That is, the mechanism used to convey the list of items to the individual affects how much "chunking" occurs. Experimentally, it has been found that auditory presentation results in a larger amount of grouping in the responses of individuals than visual presentation does. Previous literature, such as George Miller's The Magical Number Seven, Plus or ...

Internationalization is the technical activity of preparing a program, usually interactive software, to support multiple locales.
