Understanding Compression Algorithms
Compression algorithms are designed to reduce data size, which can be useful for saving storage space or speeding up data transfer over networks. The essential goal is to make data smaller while ensuring it can be accurately restored to its original form. The podcast discusses several compression methods, including lossless and lossy compression. The key distinction is that lossless compression retains all original data, allowing for exact recovery, while lossy compression sacrifices some data for greater size reduction.
