The PAQ Data Compression Programs. Matt Mahoney. PAQ is a series of open source data compression archivers that have evolved through collaborative development to top rankings on several benchmarks measuring compression ratio (although at the expense of speed and memory usage).
Compression and decompression times are about the same. Times are timer 3.01 process times in seconds on a 2.2 GHz Athlon-64 3500+, 2 GB, WinXP SP2, 32 bit. Other data compresses the same in paq8n and paq8o. paq8osse is included in the paq8o distribution. It is for processors supporting SSE2 such as the Pentium 4 and Athlon.
Audio data compression, not to be confused with dynamic range compression, has the potential to reduce the transmission bandwidth and storage requirements of audio data. Audio compression algorithms are implemented in software as audio codecs. Lossy audio compression algorithms provide higher compression at the cost of fidelity and are used in ...
A novel data-compression technique for faster computer programs Researchers free up more bandwidth by compressing 'objects' within the memory hierarchy
A novel technique rethinks hardware data compression to free up more memory used by computers and mobile devices, allowing them to run faster and perform more tasks simultaneously. Data ...
Data compression leverages redundant data to free up storage capacity, boost computing speeds, and provide other perks. In current computer systems, accessing main memory is very expensive compared to actual computation. Because of this, using data compression in the memory helps improve performance, as it reduces the frequency and amount of data programs need to fetch from main memory.

With the right file compression software, sharing and archiving files is easy. The ever-growing size of hard drives means the need to reduce file sizes when storing data has been reduced, but SDDs ...
^ Tar implementations call external programs (like compress, gzip or bzip2 or any other programs working with abstract streams and supporting the "-d" option) to perform (de)compression, and allowing you to implement your own filters. These external programs may be shipped with your Operating System.
