File Archival Techniques Using Data Compression Michael Pechura Cleveland State University 1. Introduction Small computers, like large main- frames, have had to address the ever- increasing demand for mass storage capability. In large systems, this need has been met by the inclusion of additional, perhaps larger and faster storage devices. While this is also a possible solution in the case of

Compression Techniques (Linktionary term)

Data Compression 5. OTHER ADAPTIVE METHODS. Two more adaptive data compression methods, algorithm BSTW and Lempel-Ziv coding, are discussed in this section. Like the adaptive Huffman coding techniques, these methods do not require a first pass to analyze the characteristics of the source. Thus, they provide coding and transmission in real time. However, these schemes

Audio Compression Techniques

In information technology, lossy compression or irreversible compression is the class of data encoding methods that uses inexact approximations and partial data discarding to represent the content. These techniques are used to reduce data size for storing, handling, and transmitting content. The different versions of the photo of the cat to the right show how higher degrees of approximation
