Glossary subnet A portion of a network, which may be a physically independent network segment, that shares a network address with other portions of the network and is distinguished by a subnet number. A subnet is to a network what a network is to an internet. superuser A privileged account with unrestricted access to all commands and all files regardless of permissions. The user name of this account is root. system configuration utility (SCU) A software utility used to configure Intel nodes that support Extended Industry Standard Architecture (EISA) expansion boards. system console A general term applying to any System Control Facility (SCF) workstation. System consoles are used for system operations (Exec logical console) and system control (partitioning, initializing, booting, and maintaining). System Control Facility (SCF) A set of workstations, connected in a local area network, that provides an operator interface to a ClearPath IX server. The SCF provides system operator console and system control functions through a minimum of two workstations. System configuration functions are provided through the workstation on which the Site Configuration Management System (SCMS) runs (referred to as the site data facility, or SDF). T TAS TCP TCP/IP Acronym for TCP/IP Application Services. See transmission control protocol. See transmission control protocol/internet protocol. third-generation language (3GL) High-level programming languages such as C, COBOL, and FORTRAN. 3GLs hide much of the complexity of machine processing from programmers, allowing them to focus more on the problem to be solved. Programs written in 3GLs are more machine-independent than programs written in assembly (second-generation) languages. TIP See Transaction Processing.

Glossary token ring A type of local area network (LAN) in which devices are connected to a network cable in a ring configuration. Before devices can transmit, they must possess a logical token, which is passed from device to device in sequence around the ring. When a device has something to transmit, it labels the token as busy until the transmission is complete. When the transmission is complete, the token is labeled not busy and the token is again passed around the ring. The IEEE 802.5 standard defines a token ring type of network. transaction A complete unit of work that transforms a database from one consistent state to another. In distributed transaction processing (DTP), a transaction can include multiple units of work performed on one or more systems. See also ACID properties, global transaction, X/Open Distributed Transaction Processing model. Transaction Processing (TIP) The Unisys software that provides a form of immediate data processing in which user requests are entered directly at the terminal and online programs satisfy the requests (for example, by updating database files and displaying output messages). An OS 2200 transaction processing environment is also called a TIP environment. See also High- Volume Transaction Processing (HVTIP). TransIT Open/OLTP Transaction Manager (OLTP-TM2200) The Unisys implementation of an X/Open compliant transaction manager (TM) in the OS 2200 environment. OLTP-TM2200 software provides an open, standards-compliant environment for developing distributed transaction processing (DTP) applications. See also ACID properties, global transaction, online transaction processing (OLTP), X/Open Distributed Transaction Processing model, TUXEDO Transaction Manager. transmission control protocol (TCP) A connection-oriented transport-layer protocol in the TCP/IP suite of protocols. TCP provides end-to-end reliability, error recovery, and multiplexing for the upper-layer protocols. TCP/IP applications such as simple mail transfer protocol (SMTP), file transfer protocol (FTP), and TELNET use TCP. transmission control protocol/internet protocol (TCP/IP) An open systems network architecture and set of communications protocols. It was developed by the U.S. Department of Defense to promote compatibility among US military, government, and research communications networks. It has since become popular in the private sector as a method of interconnecting systems from different vendors on local area networks (LAN) and wide area networks (WAN). Transport Service Access Method (TSAM) A program interface that allows Unisys and user-written applications to access the communications services of CMS 1100 at the transport layer. TSAM provides access to the CMS 1100 DCA, OSI, and TCP/IP protocol stacks. tuning script An initialization program (supplied by Unisys), written in Bourne shell script, that is run to initialize kernel parameters, partition disks, and install software. 7850 5104–009 Version 009B (Web Only) Glossary–25
