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.

Frequently Asked Questions
When will I have access to the lectures and assignments?
Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:
- The course may not offer an audit option. You can try a Free Trial instead, or apply for Financial Aid.
- The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
