Application and System Protection

OS/2 2.0 is a platform ideally suited for running mission-critical and line-of-business applications. OS/2 2.0 is a protected system and application environment. OS/2 is designed so that each application is encapsulated in its own address space and cannot access system or other application data. Sessions that contain DOS and Windows applications run in the protected mode of the Intel (or compatible) 80386SX (or higher) microprocessor. If a Windows or DOS application that is running in a window attempts to violate the integrity of the system, the application usually will be ended without affecting the system and other active applications. And, if a DOS or Windows application fails, for example, from unrecoverable application errors (UAEs), the session can be closed and normally restarted easily, without affecting the other applications running on the system.
