OS/2 2.0 supports the Intel (or compatible) 80386SX (or higher) microprocessor architecture. It also has the ability to run multiple DOS applications concurrently, with full preemptive (allows higher priority task to interrupt) multitasking and memory protection for each application. Windows applications also are supported in the same way.
This chapter describes some of the functional characteristics of the OS/2 operating system, such as managing memory, file systems, tasks, and devices.
