The Open Systems Adapter (OSA) is a network controller for IBM z/Architecture, ES/9000 and S/390 mainframes. The OSA can be installed in a mainframe I/O cage. The OSA supports Ethernet, Token Ring and FDDI connectivity. The maximum data rate is 10 Gbps. [1] [2] [3]
The System Support Program (SSP) was the only operating system of the S/36. It contained support for multiprogramming, multiple processors, 80 devices, job queues, printer queues, security, indexed file support, and fully installed, it was about 10MB. On the Advanced/36, the number of workstations/printers was increased to 160.

The IBM z13 was the last z Systems server to support running an operating system in ESA/390 architecture mode. [10] However, all 24-bit and 31-bit problem-state application programs originally written to run on the ESA/390 architecture readily run unaffected by this change.
The support began with MVS/SP V4R3, and IBM has obtained UNIX 95 certification for z/OS V1R2 and later. [5] The system is typically used in business and banking, and applications are often written in COBOL. COBOL programs were traditionally used with transaction processing systems like IMS and CICS. For a program running in CICS, special EXEC ...
Products, services, and subsidiaries have been offered from International Business Machines (IBM) Corporation and its predecessor corporations since the 1890s. [1] This list comprises those offerings and is eclectic; it includes, for example, the AN/FSQ-7, which was not a product in the sense of offered for sale, but was a product in the sense of manufactured—produced by the labor of IBM.
