  • nuclear regulatory commission — an independent agency, created in 1975, that licenses and regulates the nonmilitary use of nuclear energy. Abbreviation: NRC.
  • object compatibility standard — (OCS) An 88open standard for compilers and linkers.
  • on-line analytical processing — (database)   (OLAP) A category of database software which provides an interface such that users can transform or limit raw data according to user-defined or pre-defined functions, and quickly and interactively examine the results in various dimensions of the data. OLAP primarily involves aggregating large amounts of diverse data. OLAP can involve millions of data items with complex relationships. Its objective is to analyze these relationships and look for patterns, trends, and exceptions. The term was originally coined by Dr. Codd in 1993 with 12 "rules". Since then, the OLAP Council, many vendors, and Dr. Codd himself have added new requirements and confusion. Richard Creeth and Nigel Pendse define OLAP as fast analysis of shared multidimensional information. Their definition requires the system to respond to users within about five seconds. It should support logical and statistical processing of results without the user having to program in a 4GL. It should implement all the security requirements for confidentiality and concurrent update locking. The system must provide a multidimensional conceptual view of the data, including full support for multiple hierarchies. Other aspects to consider include data duplication, RAM and disk space requirements, performance, and integration with data warehouses. Various bodies have attempted to come up with standards for OLAP, including The OLAP Council and the Analytical Solutions Forum (ASF), however, the Microsoft OLE DB for OLAP API is the most widely adopted and has become the de facto standard.
  • optical character recognition — the process or technology of reading data in printed form by a device (optical character reader) that scans and identifies characters. Abbreviation: OCR.

  • rapid application development — (programming)   (RAD) A loose term for any software life-cycle designed to give faster development and better results and to take maximum advantage of recent advances in development software. RAD is associated with a wide range of approaches to software development: from hacking away in a GUI builder with little in the way of analysis and design to complete methodologies expanding on an information engineering framework. Some of the current RAD techniques are: CASE tools, iterative life-cycles, prototyping, workshops, SWAT teams, timebox development, and Re-use of applications, templates and code.

  • secure file transfer protocol — SSH File Transfer Protocol
  • send someone/something flying — If you send someone or something flying or if they go flying, they move through the air and fall down with a lot of force.
  • serial line internet protocol — (communications, protocol)   (SLIP) Software allowing the Internet Protocol (IP), normally used on Ethernet, to be used over a serial line, e.g. an EIA-232 serial port connected to a modem. It is defined in RFC 1055. SLIP modifies a standard Internet datagram by appending a special SLIP END character to it, which allows datagrams to be distinguished as separate. SLIP requires a port configuration of 8 data bits, no parity, and EIA or hardware flow control. SLIP does not provide error detection, being reliant on other high-layer protocols for this. Over a particularly error-prone dial-up link therefore, SLIP on its own would not be satisfactory. A SLIP connection needs to have its IP address configuration set each time before it is established whereas Point-to-Point Protocol (PPP) can determine it automatically once it has started. See also SLiRP.
  • sexually transmitted diseases — any disease characteristically transmitted by sexual contact, as gonorrhea, syphilis, genital herpes, and chlamydia. Abbreviation: STD.
  • shipshape and bristol fashion — in good order; efficiently arranged
  • simple mail transfer protocol — (messaging)   (SMTP) A protocol defined in STD 10, RFC 821, used to transfer electronic mail between computers, usually over Ethernet. It is a server to server protocol, so other protocols are used to access the messages. The SMTP dialog usually happens in the background under the control of the message transfer agent, e.g. sendmail but it is possible to interact with an SMTP server using telnet to connect to the normal SMTP port, 25. E.g. telnet mhs-relay.ac.uk 25 You should normally start by identifying the local host: HELO wombat.doc.ic.ac.uk You can then issue commands to verify an address or expand an alias: VRFY [email protected] VRFY postmaster or expand a mailing list: EXPN c-help You can even send a message: MAIL From:<[email protected]> RCPT To:<[email protected]> DATA What is the point? . QUIT This is useful if you want to find out exactly what is happening to your message at a certain point. See also Post Office Protocol, RFC 822, sendmail.
  • single edge contact cartridge — (hardware)   (SEC, SECC) The cased daughterboard housing Intel's Pentium II, Pentium III, and Xeon microprocessors. A SECC fits into a Slot 1 or Slot 2 connector.
  • small business administration — a federal agency, created in 1953, that grants or guarantees long-term loans to small businesses. Abbreviation: SBA, S.B.A.
  • suppressed carrier modulation — an amplitude-modulated wave in which only the sidebands are transmitted, the carrier being removed
  • symbolic automatic integrator — (mathematics, tool)   (SAINT) A symbolic mathematics program written in Lisp by J. Slagle at MIT in 1961.
  • synchronous digital hierarchy — (communications, standard)   (SDH) An international digital telecommunications network hierarchy which standardises transmission around the bit rate of 51.84 megabits per second, which is also called STS-1. Multiples of this bit rate comprise higher bit rate streams. Thus STS-3 is 3 times STS-1, STS-12 is 12 times STS-1, and so on. STS-3 is the lowest bit rate expected to carry ATM traffic, and is also referred to as STM-1 (Synchronous Transport Module-Level 1). The SDH specifies how payload data is framed and transported synchronously across optical fibre transmission links without requiring all the links and nodes to have the same synchronized clock for data transmission and recovery (i.e. both the clock frequency and phase are allowed to have variations, or be plesiochronous). SDH offers several advantages over the current multiplexing technology, which is known as Plesiochronous Digital Hierarchy. Where PDH lacks built-in facilities for automatic management and routing, and locks users into proprietary methods, SDH can improve network reliability and performance, offers much greater flexibility and lower operating and maintenance costs, and provides for a faster provision of new services. Under SDH, incoming traffic is synchronized and enhanced with network management bits before being multiplexed into the STM-1 fixed rate frame. The fundamental clock frequency around which the SDH or SONET framing is done is 8 KHz or 125 microseconds. SONET (Synchronous Optical Network) is the American version of SDH.

  • translation look-aside buffer — (storage, architecture)   (TLB) A table used in a virtual memory system, that lists the physical address page number associated with each virtual address page number. A TLB is used in conjunction with a cache whose tags are based on virtual addresses. The virtual address is presented simultaneously to the TLB and to the cache so that cache access and the virtual-to-physical address translation can proceed in parallel (the translation is done "on the side"). If the requested address is not cached then the physical address is used to locate the data in main memory. The alternative would be to place the translation table between the cache and main memory so that it will only be activated once there was a cache miss.
  • trinitrophenylmethylnitramine — tetryl.
  • universal resource identifier — (web)   (URI, originally "UDI" in some WWW documents) The generic set of all names and addresses which are short strings which refer to objects (typically on the Internet). The most common kinds of URI are URLs and relative URLs. URIs are defined in RFC 1630.
