As we explore these various areas, keep your eyes open for similarities in approach and design. Many teams of programmers work on the various modules and subsystems that make up the kernel. They frequently borrow methods and algorithms from one another, and there seems to be a never-ending attempt to tweak and tune them for improved performance.
