In computer science and information theory, data compression or source encoding is the process of representing information using fewer data bits (or other information-related units) according to a specific encoding mechanism than without encoding. For example, if we encode "compression" as "comp" then this article can be represented with fewer data bits. A popular example of compression is the ZIP file format used by many computers.
