Chapter 2. 2. Chapter 2 Objectives. Understand the fundamentals of numerical data representation and manipulation in digital computers.. Master the skill of converting between various radix systems.. Focus on Codes for Data Recording and Transmission. 2. The main part of Chapter 2 provides great detail about the various ways in which digital computers express numeric and non-numeric values.. These expressions are an abstraction for the way in which the values are actually stored on computer media and sent over transmission media.. Coding is what is used to create computer software, apps, and websites.. Examples:. Your operating system (OS). Apps on your phone. Facebook, . Snapchat. , . Instagram. Benefits of Coding. It empowers you to do many things you wouldn’t otherwise be able to do.. Session 2 – . Data Representation on a Computer System. Lecturer: Dr. Ebenezer . Ankrah. , Dept. of Information Studies. . Contact Information: eankrah@ug.edu.gh. Session Overview . Unlike humans, computer systems work exclusively with numbers (binary system) to process data into information. Computer systems need to work in a language they understand. However, the question is how does the computer convert data into binary system?
