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.
management information base — (networking) (MIB) A database of managed objects acessed by network management protocols. An SNMP MIB is a set of parameters which an SNMP management station can query or set in the SNMP agent of a network device (e.g. router). Standard minimal MIBs have been defined, and many hardware (and certain software, e.g. DBMS) providers have developed private MIBs in ASN.1 format allowing them to be compiled for use in a Network Management System. In theory, any SNMP manager can talk to any SNMP agent with a properly defined MIB. See also client-server model.
memorandum of understanding — a document that describes the general principles of an agreement between parties, but does not amount to a substantive contract
memory type range registers — (architecture, video) (MTRR) Registers in the Pentium Pro and Pentium II processors that can be used to specify a strategy for communication with the external memory and caches for a number of physical address ranges. Strategies include write-through, write-back, or uncached(?). Such control is useful where the memory is located on a device and is accessed via some kind of device bus, e.g. a PCI or AGP graphics card, where caching would be of no benefit.
metallic wood-boring beetle — any of numerous metallic green, blue, copper, or black beetles of the family Buprestidae, the larvae of which bore into the wood of trees.
natural language processing — (artificial intelligence) (NLP) Computer understanding, analysis, manipulation, and/or generation of natural language. This can refer to anything from fairly simple string-manipulation tasks like stemming, or building concordances of natural language texts, to higher-level AI-like tasks like processing user queries in natural language.

nude descending a staircase — a painting (1912) by Marcel Duchamp.
object relational modelling — object relational mapping
object-oriented programming — (programming) (OOP) The use of a class of programming languages and techniques based on the concept of an "object" which is a data structure (abstract data type) encapsulated with a set of routines, called "methods", which operate on the data. Operations on the data can only be performed via these methods, which are common to all objects that are instances of a particular "class". Thus the interface to objects is well defined, and allows the code implementing the methods to be changed so long as the interface remains the same. Each class is a separate module and has a position in a "class hierarchy". Methods or code in one class can be passed down the hierarchy to a subclass or inherited from a superclass. This is called "inheritance". A procedure call is described as invoking a method on an object (which effectively becomes the procedure's first argument), and may optionally include other arguments. The method name is looked up in the object's class to find out how to perform that operation on the given object. If the method is not defined for the object's class, it is looked for in its superclass and so on up the class hierarchy until it is found or there is no higher superclass. OOP started with SIMULA-67 around 1970 and became all-pervasive with the advent of C++, and later Java. Another popular object-oriented programming language (OOPL) is Smalltalk, a seminal example from Xerox's Palo Alto Research Center (PARC). Others include Ada, Object Pascal, Objective C, DRAGOON, BETA, Emerald, POOL, Eiffel, Self, Oblog, ESP, LOOPS, POLKA, and Python. Other languages, such as Perl and VB, permit, but do not enforce OOP.

perfect programmer syndrome — Arrogance; the egotistical conviction that one is above normal human error.
