Examples of 'compression function' in a sentence
Meaning of "compression function"
In computer science and cryptography, a compression function is a mathematical operation used to reduce the size or complexity of data. It takes an input and outputs a fixed-size or variable-length output. Compression functions are commonly used in hash functions and data compression algorithms, providing a way to condense information or represent it in a more efficient form without losing the original content
