Systems Network ArchitectureSystems Network Architecture (SNA) is IBM's proprietary networking architecture, created in 1974. It is a complete protocol stack for interconnecting computers and their resources. SNA describes formats and protocols but, in itself, is not a piece of software. The implementation of SNA takes the form of various communications packages, most notably Virtual Telecommunications Access Method (VTAM), the mainframe software package for SNA communications.
Virtual machineIn computing, a virtual machine (VM) is the virtualization or emulation of a computer system. Virtual machines are based on computer architectures and provide the functionality of a physical computer. Their implementations may involve specialized hardware, software, or a combination of the two.
Operating systemSoftware that manages computer hardware resourcesAn operating system (OS) is system software that manages computer hardware and software resources, and provides common services for computer programs. Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, peripherals, and other resources.
EmailElectronic mail (usually shortened to email; alternatively hyphenated e-mail) is a method of transmitting and receiving digital messages using electronic devices over a computer network. It was conceived in the late–20th century as the digital version of, or counterpart to, mail (hence e- + mail).RSCSRemote Spooling Communications Subsystem or RSCS is a subsystem ("virtual machine" in VM terminology) of IBM's VM/370 operating system which accepts files transmitted to it from local or remote system and users and transmits them to destination local or remote users and systems. RSCS also transmits commands and messages among users and systems.Binary Synchronous CommunicationsBinary Synchronous Communication (BSC or Bisync) is an IBM character-oriented, half-duplex link protocol, announced in 1967 after the introduction of System/360. It replaced the synchronous transmit-receive (STR) protocol used with second generation computers. The intent was that common link management rules could be used with three different character encodings for messages.
MVSMultiple Virtual Storage (MVS) is the most commonly used operating system on the System/370, System/390 and IBM ZIBM mainframe computers. IBM developed MVS, along with OS/VS1 and SVS, as a successor to OS/360. It is unrelated to IBM's other mainframe operating system lines, e.g., VSE, VM, TPF.

IBM bought the company and ran the operation as its Tivoli Software division. Additional products were acquired and run under the Tivoli portfolio brand. IBM began phasing out use of the Tivoli brand in 2013 and by 2016 had moved the portfolio products into a revised and rebranded hierarchy.

VM (operating system)VM, often written VM/CMS, is a family of virtual machineoperating systems used on IBM mainframes including the System/370, System/390, IBM Z and compatible systems. It replaced the older CP-67 that formed the basis of the CP/CMS operating system. It was first released as the free Virtual Machine Facility/370 for the S/370 in 1972, followed by chargeable upgrades and versions that added support for new hardware.*As an Amazon Associate I earn from qualifying purchases.
