Lossless Compression Algorithms: DEFLATE, Brotli, and Zstandard
How the most widely deployed lossless compression algorithms work, from Huffman and arithmetic coding to sliding-window dictionaries and Asymmetric Numeral Systems.
Data Compression & Digital Storage — Germany
A structured reference covering entropy coding, dictionary-based algorithms, NAND flash storage, and the file format standards that connect them all.
Each section addresses a distinct layer of the data storage and compression stack, from algorithm design to physical media.
Entropy coding, LZ-family algorithms, Huffman trees, and the DEFLATE stream format. How data is made smaller without any information loss.
Magnetic platter mechanics, NAND flash cell types, the NVMe command set, and how distributed storage systems handle redundancy.
ZIP, gzip, bzip2, zstd, Brotli, JPEG, WebP, and AV1. The container formats that combine compression with metadata and interoperability.
Each article provides a technically grounded overview with references to published specifications and standards.
How the most widely deployed lossless compression algorithms work, from Huffman and arithmetic coding to sliding-window dictionaries and Asymmetric Numeral Systems.
A technical overview of magnetic disk mechanics, NAND flash memory cell types, the PCIe/NVMe interface, and how storage controllers manage wear and latency.
ZIP, gzip, bzip2, Zstandard frames, Brotli, and media codecs: how container structures wrap compressed bitstreams and carry metadata across systems.
Xelveror is a static educational reference published in Germany. The content describes how compression and storage technologies work at a technical level, drawing on published IETF RFCs, ISO standards, and manufacturer datasheets.
Algorithm descriptions follow the formal definitions in their respective specifications. Storage benchmarks cited are drawn from publicly available sources and are presented without commercial endorsement.
