The client version of the OS/2 operating system. OS/2 Warp included peer-to-peer networking, fax and communications programs, multimedia viewing and editing applications along with IBM Works (word processing, spreadsheet, database and other office tools). There were two versions of OS/2 Warp. One required Windows 3.1 to be installed, the other included a modified version of Windows 3.1.
Introduced in late 1994, OS/2 Warp Version 3.0 was the successor to OS/2 for Windows and OS/2 Version 2.1. When first introduced, it could run in 8MB of memory; very important for its time. The last update of OS/2 Warp from IBM was Version 4.52 in 2001. See
