A device or program capable of encoding or decoding a digital data stream or signal. A codec compresses data to facilitate transmission and decompresses received data.
Compression Ratio refers to the ratio of the original file size to the compressed file size, representing the effectiveness of a compression algorithm.
Detailed overview of lossless compression, a method that allows the original data to be perfectly reconstructed.
An in-depth exploration of lossy compression, where some data is irreversibly lost to achieve higher compression ratios in various domains such as audio, video, and image files.
A comprehensive overview of lossy compression, a method that reduces file size by removing some data, often resulting in a loss of quality in audio, video, or images.
Quantization is the process of mapping a large set of values to a smaller set, fundamental in various fields such as digital signal processing, quantum mechanics, and data compression.
Variable-Length Code is a coding scheme in which codes have different lengths, often used for efficient data representation and compression.
A comprehensive guide to understanding data compression, its techniques, historical context, and applications.
Data compression is a technology that reduces the size of a computer file. It is especially important for files used on web pages, such as graphics and sound files, which are compressed to facilitate faster downloads. Compression methods are typically classified as lossless or lossy.
An in-depth look at the Graphics Interchange Format (GIF), its history, usage, technical specifics, and its place in today’s digital, social, and online communications.
Redundancy refers to the intentional or unintentional repetition of components or data, enhancing reliability and robustness in systems. It is a fundamental principle in engineering, computing, and data management.
