  • life-support machine — A life-support machine is the equipment that is used to keep a person alive when they are very ill and cannot breathe without help.
  • light the touchpaper — to do something that will cause much anger or excitement
  • light-weight process — (operating system, parallel)   (LWP) A single-threaded sub-process which, unlike a thread, has its own process identifier and may also differ in its inheritance and controlling features. Several operating systems, e.g. SunOS 5.x, provide system calls for creating and controlling LWPs.
  • lighthouse coffeepot — a coffeepot of the late 17th and 18th centuries, having a tapering, circular body with a domed lid.
  • linear address space — A memory addressing scheme used in processors where the whole memory can be accessed using a single address that fits in a single register or instruction. This contrasts with a segmented memory architecture, such as that used on the Intel 8086, where an address is given by an offset from a base address held in one of the "segment registers". Linear addressing greatly simplifies programming at the assembly language level but requires more instruction word bits to be allocated for an address.
  • linguistic geography — dialect geography.
  • liquidity preference — (in Keynesian economics) the degree of individual preference for cash over less liquid assets.
  • lost property office — room for mislaid objects
  • lower layer protocol — (networking, protocol)   (LLP, or lower-layer protocol) Any protocol residing in OSI layers one to four. These protocols package, route, verify and transmit datagrams. A prime example would be TCP/IP. Lower layer protocols support the upper layer protocols.
  • lunisolar precession — the principal component of the precession of the equinoxes, produced by the gravitational attraction of the sun and the moon on the equatorial bulge of the earth.
  • magneto-optical disk — (hardware, storage)   (MO) A plastic or glass disk coated with a compound (often TbFeCo) with special optical, magnetic and thermal properties. The disk is read by bouncing a low-intensity laser off the disk. Originally the laser was infrared, but frequencies up to blue may be possible giving higher storage density. The polarisation of the reflected light depends on the polarity of the stored magnetic field. To write, a higher intensity laser heats the coating up to its Curie point, allowing its magnetisation to be altered in a way that is retained when it has cooled. Although optical, they appear as hard drives to the operating system and do not require a special filesystem (they can be formatted as FAT, HPFS, NTFS, etc.). The initial 5.25" MO drives, introduced at the end of the 1980s, were the size of a full-height 5.25" hard drive (like in IBM PC XT) and the disks looked like a CD-ROM enclosed in an old-style cartridge In 2006, a 3.5" drive has the size of 1.44 megabyte diskette drive with disks about the size of a regular 1.44MB floppy disc but twice the thickness.
