Lossless Data Compression

Lossless data compression is a type of data compression algorithm that allows the original data to be perfectly reconstructed from the compressed data. In other words, it is a compression technique that reduces the size of the data without losing any information. This is achieved by identifying and eliminating the redundancy in the data. The most common techniques used in lossless data compression are Huffman coding, Arithmetic coding, and Lempel-Ziv-Welch (LZW) compression. Lossless data compression is widely used in various applications such as file compression, image compression, and video compression. It is particularly useful in situations where the original data cannot be altered or modified in any way, such as in medical imaging or scientific data analysis.
