The Functionality of OS/2 Warp

• The primary user interface under OS/2 Warp is the graphical, icon-based, object-oriented interface managed by the Presentation Manager. The interface operates as a subsystem under OS/2 Warp, providing all applications and users with a uniform interface.

• One of the major features of OS/2 Warp is that it was designed to take advantage of the memory-management and protection capabilities of the 80286, 80386, and other chips in this 32-bit family.

• Preemptive scheduling was designed with response to user needs taking priority over throughput.

• OS/2 Warp contains built-in connectivity features that gives the user more flexibility. With the built-in networking, the user can install networking capabilities during installation or later.

• OS/2 Warp is designed to incorporate a LAN Manager as a part of the operating system. The LAN Manager works best with networks of a client/server architecture. Added security features will appear throughout the life of OS/2 Warp as its use in multiuser systems grows and the distributed applications become more sophisticated.

• OS/2 Warp also provides a very important feature for multitasking by making asynchronous reads and writes to I/O. That is, control may be returned to the calling thread after an I/O request is made but before it is complete.

• OS/2 Warp is a true objected-oriented interface. The underlying System Object Model provides complete object-tracking so simple operations like dragging a directory to another directory won't invalidate links and other interface structures.
