Universal code, in the context of data compression, refers to a family of compression methods that can effectively compress data from any source, not just specific types of data or fixed patterns. The idea is to create compression algorithms that do not need prior knowledge of the source data distribution to achieve good performance. ### Characteristics of Universal Codes: 1. **Source Independence**: Universal codes can compress data from any source, without requiring a model that describes the statistical properties of the source data.
