  • international morse code — a form of Morse code used in international radiotelegraphy.
  • internet access provider — (networking, company)   (IAP) A company or other origanisation which provides access to the Internet to businesses and/or consumers. An IAP purchases an Internet link from another company that has a direct link to the Internet and resells portions of that bandwidth to the general public. For example, an IAP may purchase a T1 link (1.544Mb/s) and resell that bandwidth in chunks consisting of ISDN (64Kb/s, 128Kb/s) and analog modems (14.4Kb/s, 28.8Kb/s). The IAP's customer base is likely to include both businesses and individuals. Individual customers usually connect to the IAP via a modem and telephone line to a (preferably local) point of presence. An IAP may also be an Internet Service Provider.
  • iterated function system — (graphics)   (IFS) A class of fractals that yield natural-looking forms like ferns or snowflakes. Iterated Function Systems use a very easy transformation that is done recursively.

  • liquid components of gas — Liquid components of gas are associated hydrocarbons in natural gas, which include ethane, propane, and butane.
  • logical block addressing — (storage)   (LBA) A hard disk sector addressing scheme used on all SCSI hard disks, and on ATA-2 conforming IDE hard disks. The addressing conversion is performed by the hard disk firmware. Prior to LBA, combined limitations of IBM PC BIOS and ATA restricted the useful capacity of IDE hard disks on IBM PCs and compatibles to 1024 cylinders * 63 sectors per track * 16 heads * 512 bytes per sector = 528 million bytes = 504 megabytes. Modern BIOSes select LBA mode automatically, and work around the 1024-cylinder BIOS limit by representing a hard disk to the OS as having e.g. half as many cylinders and twice as many heads. However, there is still an unbreakable BIOS disk size limit of 1024 cylinders * 63 sectors per track * 256 heads * 512 bytes per sector = 8 gigabytes, but modern OSes (including Windows 9x, Windows NT and Linux) are not affected by it, since they issue direct LBA-based calls, bypassing the BIOS hard disk services completely.
  • long-spined sea scorpion — Cottus bubalis or Taurulus bubalis
  • longitudinal coefficient — the ratio of the immersed volume of a hull to the product obtained by multiplying its length on the water line by the immersed area of the midship transverse section, all assuming a given depth of immersion of the hull.

  • mandy rice-davis applies — (chat)   (MRDA) An acronym used to imply that someone is lying to protect their own interests. During the trial of Stephen Ward (who was charged with living off the immoral earnings of Christine Keeler and Rice-Davies), the prosecuting counsel pointed out that Lord Astor denied any involvement with her and Rice-Davies replied, "Well, he would, wouldn't he?"

  • negative acknowledgement — 1.   (character)   (NAK) The mnemonic for ASCII character 21. Sometimes used as the response to receipt of a corrupted packet of information. Opposite of acknowledgement. 2.   (communications)   (NAK) Any message transmitted to indicate that some data has been received incorrectly, for example it may have a checksum or message length error. A NAK message allows the sender to distinguish a message which has been received in a corrupted state from one which is not received at all. An alternative is to use only ACK messages, in which case the non-receipt of an ACK after a certain time is counted as a NAK but gives no information about the integrity of the communications channel. See also ACK.
  • object-oriented analysis — (programming)   (OOA) The first phase of object-oriented design.
  • object-oriented database — (database)   (OODB) A system offering DBMS facilities in an object-oriented programming environment. Data is stored as objects and can be interpreted only using the methods specified by its class. The relationship between similar objects is preserved (inheritance) as are references between objects. Queries can be faster because joins are often not needed (as in a relational database). This is because an object can be retrieved directly without a search, by following its object id. The same programming language can be used for both data definition and data manipulation. The full power of the database programming language's type system can be used to model data structures and the relationship between the different data items. OODBs typically provide better support for versioning. An object can be viewed as the set of all its versions. Also, object versions can be treated as full fledged objects. OODBs also provide systematic support for triggers and constraints which are the basis of active databases. Most, if not all, object-oriented application programs that have database needs will benefit from using an OODB.
  • object-oriented language — object-oriented programming
  • open data-link interface — (networking, standard)   (ODI) A Novell-developed network card API that provides media and protocol independence. It allows the sharing of a single card by multiple transport layer protocols and resolves conflicts.

  • recursive descent parser — (grammar)   A "top-down" parser built from a set of mutually-recursive procedures or a non-recursive equivalent where each such procedure usually implements one of the productions of the grammar. Thus the structure of the resulting program closely mirrors that of the grammar it recognises.
  • relative record data set — (database)   (RRDS) One of the access methods used by IBM's VSAM.
  • remote method invocation — (programming)   (RMI) Part of the Java programming language library which enables a Java program running on one computer to access the objects and methods of another Java program running on a different computer.
