5 Data in depth
This chapter covers
- Learning how the computer represents data
- Building a working CPU emulator
- Creating your own numeric data type
- Understanding floating-point numbers
This chapter is all about understanding how zeroes and ones can become much larger objects like text, images, and sound. We will also touch on how computers do computation.
By the end of the chapter, you will have emulated a fully functional computer with CPU, memory, and user-defined functions.
