A common critique of the text is its lingering reliance on Unix/Linux and Windows examples to the exclusion of other architectures. While the 8th edition introduces mobile OSs, the deep-dive examples often remain rooted in traditional PC architectures.

Modern operating systems rely heavily on Virtual Memory to run programs larger than the physical RAM available. The Memory Manager divides programs into equal-sized pieces called and divides physical memory into matching blocks called page frames .
