It consists of three separate but related issues: data alignment, data structure padding, and packing. The CPU in modern computer hardware performs reads and writes to memory most efficiently when the data is naturally aligned , which generally means that the data's memory address is a multiple of the data size.
In cryptography, padding is any of a number of distinct practices which all include adding data to the beginning, middle, or end of a message prior to encryption. In classical cryptography, padding may include adding nonsense phrases to a message to obscure the fact that many messages end in predictable ways, e.g. sincerely yours.
The proof that P = NP implies EXP = NEXP uses "padding".. by definition, so it suffices to show .. Let L be a language in NEXP. Since L is in NEXP, there is a non-deterministic Turing machine M that decides L in time for some constant c.
In computing, output padding is the insertion of non-printing characters into the device output stream to allow for a preceding control operation to take effect. Output padding was necessary on many printing devices, notably Teletype and other mechanical terminals, after the issuance of a carriage return . [ 1 ]
Computer programming or coding is the composition of sequences of instructions, called programs, that computers can follow to perform tasks. [1] [2] It involves designing and implementing algorithms, step-by-step specifications of procedures, by writing code in one or more programming languages.
Padding is a soft material used for the sake of comfort or to change the shape of something. Padding may also refer to: Schedule padding, time added to a transportation schedule making it resilient to delay; Padding argument, method of proving that some complexity classes are conditionally equal

In data deduplication, data synchronization and remote data compression, Chunking is a process to split a file into smaller pieces called chunks by the chunking algorithm.
