: This architecture treats all RAM and disk storage as one massive virtual address space, simplifying data management. Why It’s Still Relevant in 2026 Evolution and Rebranding : Hardware consolidated into IBM
The (Application System/400), introduced in 1988, is a renowned family of midrange computers designed for business applications. While the original hardware is no longer in production, its core architecture lives on in today’s IBM Power Systems running the IBM i operating system. Evolution and Rebranding and devices—is treated as an object
: Hardware consolidated into IBM Power Systems , with the operating system becoming IBM i . Core Architectural Features
: Everything on the system—files, programs, and devices—is treated as an object , which significantly enhances security and stability.
: This layer separates applications from the underlying hardware, allowing companies to upgrade to new processors (like Power10) without modifying their software.
