Structures for Data Compression

The goal of data compression is to represent an information source as accurately as possible using the smallest storage space (=number of bits).
This lesson is focused on the compression concepts and techniques. After an introduction of some of the most important general compression concepts, the lesson makes a distinction between different types of data. The closer examination of various techniques of data compression allows you to become familiar with this topic.
