  • link state routing protocol — (networking, communications)   A routing protocol such as OSPF which permits routers to exchange information with one another about the reachability of other networks and the cost or metric to reach the other networks. The cost/metric is based on number of hops, link speeds, traffic congestion, and other factors as determined by the network designer. Link state routers use Dijkstra's algorithm to calculate shortest (lowest cost) paths, and normally update other routers with whom they are connected only when their own routing tables change. Link state routing is an improvement over distance-vector routing protocols such as RIP which normally use only a single metric (such as hop count) and which exchange all of their table information with all other routers on a regular schedule. Link state routing normally requires more processing but less transmission overhead.
  • magnetostrictive delay line — (storage, history)   An early storage device that used tensioned wires of nickel alloy carrying longitudinal waves produced and detected electromagnetically. They had better storage behaviour than mercury delay lines.

  • portable scheme interpreter — (PSI) A portable scheme interpreter by Ozan Yigit <[email protected]>, David Keldsen and Pontus Hedman that includes a simple DAG compiler and a virtual machine. It can be used as an integrated extension interpreter in other systems and allows easy addition of new primitives. There are some unique debugging and tracing facilities. Acceptable performance results from a fairly straight-forward implementation. Continuations are fully and portably supported and perform well. PSI is based on the simple compilers and virtual machine in Kent Dbyvig's thesis. The pre-release version conforms to R4RS with a number of useful extensions.

  • scalable coherent interface — (hardware, protocol)   (SCI) The ANSI/IEEE 1596-1992 standard that defines a point-to-point interface and a set of packet protocols. The SCI protocols use packets with a 16-byte header and 16, 64, or 256 data bytes. Each packet is protected by a 16-bit CRC code. The standard defines 1 Gbit/second serial fiber-optic links and 1 Gbyte/second parallel copper links. SCI has two unidirectional links that operate concurrently. The SCI protocols support shared memory by encapsulating bus requests and responses into SCI request and response packets. Packet-based handshake protocols guarantee reliable data delivery. A set of cache coherence protocols are defined to maintain cache coherence in a shared memory system. SCI uses 64-bit addressing and the most significant 16 bits are used for addressing up to 64K nodes.

  • serial peripheral interface — (communications, hardware)   (SPI) A serial interface in which a master device supplies clock pulses to exchanges data serially with a slave over two data wires (Master-Slave and Slave-Master). This term probably originated with Motorola in about 1979 with their first all-in-one microcontroller.
  • serial storage architecture — (storage)   (SSA) IBM's proposed ANSI standard for a standard high-speed interface to disk clusters and arrays. SSA allows full-duplex packet multiplexed serial data transfers at rates of 20Mb/sec in each direction. According to John Taylor, programme manager at IBM's Storage Division at Havant, SSA will be used in arrays of discs working with high-end computers ranging from mainframes down to LAN servers. Taylor said that SSA differs from the IEEE proposed P1394 serial interface specification in its ability to offer simultaneous multiplexed transfers from more than one disk or array. IBM also supports the P1394 standard which will be used primarily by desktop PCs for multimedia applications. SSA has received backing from a number of companies including connector makers Molex, ITT Cannon and AMP, disk drive makers Conner and Western Digital and RAID array suppliers like Dynatech and NCR. IBM expects to see the first SSA products released at Comdex in Autumn 1994 but it will be 1995 before the products ship in volume. Under an agreement signed with ASIC maker and ARM licencee VLSI Technology, IBM will use ARM-based chips made by VLSI to implement the SSA interface and VLSI will make these cores available to third parties as one of its Functional System Blocks.
  • session initiation protocol — (protocol)   (SIP) A very simple text-based application-layer control protocol. It creates, modifies, and terminates sessions with one or more participants. Such sessions include Internet telephony and multimedia conferences. It is described in RFC 2543.

  • stock market closing report — a summary of the prices of stocks and shares at the end of trading including information about their gains or losses over the trading period
  • synchronous optical network — (networking)   (SONET) A broadband networking standard based on point-to-point optical fibre networks. SONET will provide a high-bandwidth "pipe" to support ATM-based services. The SONET standard will establish a digital hierarchical network with a consistent worldwide transport scheme. SONET has been designed to take advantage of fibre, in contrast to the plain old telephone system which was designed for copper wires. SONET carries circuit-switched data in frames at speeds in multiples of 51.84 megabits per second (Mbps) up to 48 * 51.84 Mbps = 2.488 gigabits per second. Since SONET uses multiple channels to transmit data, each SONET frame can be considered to be a two-dimensional table of bytes that is 9 rows high and 90 columns deep. For every OC-n level, SONET can transmit n number of frames at a given time. Groups of frames are called superframes. SONET is the American version of SDH.

  • third law of thermodynamics — any of three principles variously stated in equivalent forms, being the principle that the change of energy of a thermodynamic system is equal to the heat transferred minus the work done (first law of thermodynamics) the principle that no cyclic process is possible in which heat is absorbed from a reservoir at a single temperature and converted completely into mechanical work (second law of thermodynamics) and the principle that it is impossible to reduce the temperature of a system to absolute zero in a finite number of operations (third law of thermodynamics)

  • universal computer protocol — (communications, protocol)   An earlier form of External Machine Interface (EMI).
  • universal naming convention — (networking)   (UNC) The type of file system path used in Microsoft Windows networking to completely specify a directory on a file server. The basic format is: \\servername\sharename where "servername" is the hostname or IP address of a network file server, and "sharename" is the name of a shared directory on the server. This is related to the conventional MS-DOS "C:\windows" style of directory name. E.g. \\server1\dave might be set up to point to C:\users\homedirs\dave on a server called "server1". It is possible to execute a program using this convention without having to specifically link a drive, by running: \\server\share\directory\program.exe The undocumented DOS command, TRUENAME can be used to find out the UNC name of a file or directory on a network drive. Even Microsoft don't know whether UNC stands for "Universal Naming Convention" or "Uniform Naming Convention", both appear on their website, sometimes withing the same document, but with a preference for "Universal".
