  • knowledge-based system — (artificial intelligence)   (KBS) A program for extending and/or querying a knowledge base. The related term expert system is normally used to refer to a highly domain-specific type of KBS used for a specialised purpose such as medical diagnosis. The Cyc project is an example of a large KBS.

  • memory management unit — (hardware, memory management)   (MMU, "Paged Memory Management Unit", PMMU) A hardware device or circuit that supports virtual memory and paging by translating virtual addresses into physical addresses. The virtual address space (the range of addresses used by the processor) is divided into pages, whose size is 2^N, usually a few kilobytes. The bottom N bits of the address (the offset within a page) are left unchanged. The upper address bits are the (virtual) page number. The MMU contains a page table which is indexed (possibly associatively) by the page number. Each page table entry (PTE) gives the physical page number corresponding to the virtual one. This is combined with the page offset to give the complete physical address. A PTE may also include information about whether the page has been written to, when it was last used (for a least recently used replacement algorithm), what kind of processes (user mode, supervisor mode) may read and write it, and whether it should be cached. It is possible that no physical memory (RAM) has been allocated to a given virtual page, in which case the MMU will signal a "page fault" to the CPU. The operating system will then try to find a spare page of RAM and set up a new PTE to map it to the requested virtual address. If no RAM is free it may be necessary to choose an existing page, using some replacement algorithm, and save it to disk (this is known as "paging"). There may also be a shortage of PTEs, in which case the OS will have to free one for the new mapping. In a multitasking system all processes compete for the use of memory and of the MMU. Some memory management architectures allow each process to have its own area or configuration of the page table, with a mechanism to switch between different mappings on a process switch. This means that all processes can have the same virtual address space rather than require load-time relocation. An MMU also solves the problem of fragmentation of memory. After blocks of memory have been allocated and freed, the free memory may become fragmented (discontinuous) so that the largest contiguous block of free memory may be much smaller than the total amount. With virtual memory, a contiguous range of virtual addresses can be mapped to several non-contiguous blocks of physical memory. In early designs memory management was performed by a separate integrated circuit such as the MC 68851 used with the Motorola 68020 CPU in the Macintosh II or the Z8015 used with the Zilog Z80 family of processors. Later CPUs such as the Motorola 68030 and the ZILOG Z280 have MMUs on the same IC as the CPU.
  • monday morning disease — azoturia (def 2).
  • myalgic encephalopathy — a condition characterized by painful muscles, extreme fatigue, and general debility, sometimes occurring as a sequel to viral illness
  • native language system — (NLS) A set of interfaces specified by X/Open for developing applications to run in different natural language environments.
  • nodal switching system — (NSS) Main routing nodes in the NSFnet backbone.
  • non-euclidean geometry — geometry based upon one or more postulates that differ from those of Euclid, especially from the postulate that only one line may be drawn through a given point parallel to a given line.
  • non-hodgkin's lymphoma — Pathology. any of several malignancies of the lymphatic system in which the cells characteristic of Hodgkin's disease are absent.
  • nonmonetary advantages — the beneficial aspects of an employment, such as the stimulation of the work, attractiveness of the workplace, or its nearness to one's home, that do not reflect its financial remuneration
  • obligational authority — the necessary authority that precedes budget spending by a government agency or department, granted by Congress through appropriations.
  • obtaining by deception — the offence of dishonestly obtaining the property of another by some deception or misrepresentation of facts
  • on a wing and a prayer — with only the slightest hope of succeeding
  • otorhinolaryngological — of or relating to the medical practice involving the ear, nose, and throat.
  • physiographic province — a geographic region in which climate and geology have given rise to an array of landforms different from those of surrounding regions.
  • picture of dorian gray — a novel (1891) by Oscar Wilde.
  • plastic pin grid array — (hardware, processor)   (PPGA) The package used for certain Intel Celeron processors. PPGA processors fit into Socket 370 motherboard sockets. The Plastic Pin Grid Array packaging is similar to that used on Pentium processors. The silicon core is covered by a heat slug that faces down toward the motherboard. The Celeron 300A to the 533 use a PPGA package. The Celeron 566 onward use a FC-PGA package. Celeron processors are also available in Slot 1 SEPP packaging.
  • play one's cards right — a usually rectangular piece of stiff paper, thin pasteboard, or plastic for various uses, as to write information on or printed as a means of identifying the holder: a 3″ × 5″ file card; a membership card.

  • saturday-night special — a cheap, small-caliber handgun that is easily obtainable and concealable.
  • spherical trigonometry — the branch of trigonometry that deals with spherical triangles.
  • system account manager — (cryptography, operating system, security)   (SAM) A password database stored as a registry file in Windows NT and Windows 2000. The System Account Manager (SAM) database stores users' passwords in a hashed format. Since a hash function is one-way, this provides some measure of security for the storage of the passwords. In an attempt to enhance the security of the SAM database against offline cracking, Microsoft introduced the SYSKEY utility in Windows NT 4.0.
  • system management mode — (hardware)   (SMM) A reduced power consumption state provided by some Intel microprocessors. When a CPU enters SMM it saves its current state in a special area of static RAM called SMRAM (System Management RAM) and then runs a program, also stored in SMRAM, the SMM handler. SMM is implemented in all Intel "SL" suffixed CPUs. In June 1993, Intel announced it was discontinuing its SL range and instead making all its current processors SL enhanced. See also Auto Idle.
  • thermal imaging system — equipment providing images of a target, or of a person or thing under examination
  • total allergy syndrome — a condition in which a person suffers from a large number of symptoms that are claimed to be caused by allergies to various substances used or encountered in modern life
  • university of michigan — (body, education)   A large cosmopolitan university in the Midwest USA. Over 50000 students are enrolled at the University of Michigan's three campuses. The students come from 50 states and over 100 foreign countries. 70% of the University's students graduated in the top 10% of their high school class. 90% rank in the top 20% of their high school class. 60% of the students receive financial aid. The main Ann Arbor Campus lies in the Huron River valley, 40 miles west of Detroit. The campus boasts 2700 acres with 200 buildings, six million volumes in 23 libraries, nine museums, seven hospitals, hundreds of laboratories and institutes, and over 18000 microcomputers.
