Porting Kernels. 2. Porting Issues - 1. Data formats vary across platforms, so data files created on platform “X” may not be usable on platform “Y.”. Binary. . formats. : different platforms use different bit patterns to represent numbers (and possibly characters).. A numbering system (base) is a way to represent numbers, base k dictates. We denote the base by adding k as a subscript at the end of the number as in 1234. 5. for base 5 (we can omit 10 if in base 10). Chapter 2. Why Binary?.

University of Bristol, UK. Why use Files?. Very small amounts of data – just hardcode them into the program. A few pieces of data – ask the user to input them. More than this, you need an external file stored on secondary storage . What is binary?. You and I write numbers like this: twelve is 12, sixty eight is 68, and one hundred is 100.
