Data compression is the science of shrinking. Compression makes the data that creates images, sounds, video and even text small enough to be sent through telephone wires--the network of the Internet.

What does data compression actually mean? Find out inside PCMag's comprehensive tech and computer-related encyclopedia.

Data compression is a promising way to accelerate irregular applications by reducing memory traffic. However, software compression adds substantial overheads, and prior hardware compression techniques ...

Data Compression Strategies Table 27-1 shows two different ways that data compression algorithms can be categorized. In (a), the methods have been classified as either lossless or lossy . A lossless ...

Even if you use a “real” compression algorithm, they will almost always perform better if the data to compress has more repeating sequences.

Compression even your Mom will loveThe compression ratio is better than 4:1. Try that with Lempel-Ziv!

A compression technique that does not decompress digital data back to 100% of the original. Lossy methods can provide high degrees of compression and result in smaller compressed files, but some ...

Transform compression is based on a simple premise: when the signal is passed through the Fourier (or other) transform, the resulting data values will no longer be equal in their information carrying ...
