Data compression is the process of lowering the number of bits required to represent information. Because of its smaller size, compressed data is more faster to send and less costly to store, freeing up storage and improving network capacity. Data compression algorithms are algorithms that conduct data compression. There are two types of data compression algorithms: lossy and lossless. Lossy compression techniques compress more data than lossless compression algorithms, but at the expense of losing data that cannot be restored. Lossy compression methods are commonly employed for audio and video data, where the loss in quality is bearable and frequently undetectable.
