This book investigates the architectural philosophy and internal structural mechanisms of the 32-bit OS/2 operating system. Harvey M. Deitel, an established expert in operating systems, collaborates with M. S. Kogan, a primary architect of the OS/2 platform, to document the technical rationale behind the system's development. The text provides a detailed examination of the design decisions that shaped the 32-bit environment, offering a technical framework for understanding how the system manages resources, memory, and multitasking. By synthesizing historical development context with specific engineering choices, the authors explain the logic governing the OS/2 architecture.

Experts and systems engineers recognize this work as a primary source for understanding the specific engineering challenges of the OS/2 platform. Readers frequently note the technical density of the prose, which serves as a foundational reference for those studying the history of operating system architecture.
