Data Representation
In this module we will cover three key concepts: data storage, data representation and data compression. You will learn about the ways in which data are represented and stored in a computer, including the use of bit patterns to represent different types of data, the types of hardware used to represent data, and data compression algorithms. You will use this understanding to reason about computer systems and solve problems.
