  • portable network graphics — (file format)   /ping/ (PNG) An extensible file format for the lossless, portable, well-compressed storage of raster images. PNG provides a patent-free replacement for GIF and can also replace many common uses of TIFF. Indexed-colour, greyscale and truecolour images are supported, plus an optional alpha channel. Sample depths range from 1 to 16 bits. PNG is designed for on-line viewing applications, such as the World Wide Web, so it is fully streamable with a progressive display option. PNG is robust, providing both full file integrity checking and simple detection of common transmission errors. Also, PNG can store gamma correction and chromaticity data for improved colour matching on heterogeneous platforms.
  • positional representation — (mathematics)   The conventional way of writing numbers as a string of digits in which each digit, D, has value D * R^I, where R is the radix or (number) base and I is the digit's position counting leftward from zero at the least significant (right-hand) end. Each digit can be zero to R-1. Each position has a weight or significance R times greater than the position to its right and the right-most place has a weight of one. Decimal numbers are radix ten, binary numbers are radix two, octal radix eight and hexadecimal radix 16. Positional representation makes arithmetic operations on large numbers much easier than, say, roman numerals. It is fundamental to the binary representation used by digital computers.
  • primary domain controller — (networking)   (PDC) Each Windows NT domain has a Primary Domain Controller and zero or more Backup Domain Controllers. The PDC holds the SAM database and authenticates access requests from workstations and servers in the domain.
  • primary management domain — (messaging)   (PRMD) The component of an X.400 electronic mail address that gives the organisation name, usually abbreviated to p= in written addresses. See also ADMD.
  • principle of least action — the principle that motion between any two points in a conservative dynamical system is such that the action has a minimum value with respect to all paths between the points that correspond to the same energy
  • principle of virtual work — the principle that the total work done by all forces on a system in static equilibrium is zero for a set of infinitesimally small displacements.
  • private international law — conflict of laws (def 2).
  • profit and loss statement — A profit and loss statement is a statement that is compiled at the end of a financial year showing that year's revenue and expense items and indicating gross and net profit or loss.

  • public key infrastructure — (cryptography, communications)   (PKI) A system of public key encryption using digital certificates from Certificate Authorities and other registration authorities that verify and authenticate the validity of each party involved in an electronic transaction. PKIs are currently evolving and there is no single PKI nor even a single agreed-upon standard for setting up a PKI. However, nearly everyone agrees that reliable PKIs are necessary before electronic commerce can become widespread.

  • radio-controlled junction — A radio-controlled junction is a piece of equipment used to control underground pipelines which connect oil tanks.
  • rate monotonic scheduling — (algorithm)   A means of scheduling the time allocated to periodic hard-deadline real-time users of a resource. The users are assigned priorities such that a shorter fixed period between deadlines is associated with a higher priority. Rate monotonic scheduling provides a low-overhead, reasonably resource-efficient means of guaranteeing that all users will meet their deadlines provided that certain analytical equations are satisfied during the system design. It avoids the design complexity of time-line scheduling and the overhead of dynamic approaches such as earliest-deadline scheduling.

  • run-time type information — (compiler)   (RTTI) Facilities included in C++ compilers to allow the type of an object to be determined at run time. This facility, found in good C++ compilers and some other high level languages, adds type information to memory resident objects (i.e. type name or unique type-id). This allows the run-time system to determine if an object is of a specific type, for example, to ensure that a cast of an object is valid.

  • single wingback formation — an offensive formation in which the wingback lines up outside of and about one yard behind an end, the quarterback lines up lateral to the wingback but about midway between the same end and the center, the fullback is three or four yards behind the middle of the line, and the tailback lines up one yard behind the fullback on the other side of the line from the wingback and quarterback.
