- password authentication protocol — (networking) (PAP) An authentication scheme used by PPP servers to validate the identity of the originator of the connection. PAP applies a two-way handshaking procedure. After the link is established the originator sends an id-password pair to the server. If authentication succeeds the server sends back an acknowledgement; otherwise it either terminates the connection or gives the originator another chance. PAP is not a strong authentication method. Passwords are sent over the circuit "in the clear" and there is no protection against playback or repeated "trial and error" attacks. The originator is in total control of the frequency and timing of the attempts. Therefore, any server that can use a stronger authentication method, such as CHAP, will offer to negotiate that method prior to PAP. The use of PAP is appropriate, however, if a plaintext password must be available to simulate a login at a remote host. PAP is defined in RFC 1334.
- plesiochronous digital hierarchy — (communications) (PDH) A transmission system for voice communication using plesiochronous synchronisation. PDH is the conventional multiplexing technology for network transmission systems. The transmitter adds dummy information bits to allow multiple channels to be bit interleaved. The receiver discards these bits once the signals have been demultiplexed. PDH combines multiple 2 Mb/s (E1) channels in Europe and 1.544 Mb/s (DS1) channels in the US and Japan. PDH is being replaced by SONET and other SDH (Synchronous Digital Hierarchy) schemes.
- pleuk grammar development system — (grammar, tool) A shell for grammar development by Jo Calder <[email protected]>, Kevin Humphreys <[email protected]>, Chris Brew <[email protected]>, and Mike Reape <[email protected]>. It handles various grammatical formalisms and requires SICStus Prolog version 2.1#6 or later. E-mail: <[email protected]>.
- point-to-point protocol over atm — (networking) (PPPoA) A network protocol for encapsulating PPP frames in ATM AAL5. It is used mainly with cable modem, DSL and ADSL services. PPPoA offers standard PPP features such as authentication, encryption, and compression. It is very slightly more efficient than PPPoE and, like PPPoE, supports VC-MUX and LLC encapsulation. PPPoA is specified in RFC 2364.
- portable common tool environment — (tool) (PCTE) An ECMA standard framework for software tools developed in the Esprit programme. It is based on an entity-relationship Object Management System and defines the way in which tools access this.
- probability of failure on demand — (systems) (POFOD) The likelihood that some system will fail when a service request is made.
- professional liability insurance — Professional liability insurance is insurance for a company or a professional person against claims or financial losses that may occur as a result of their negligence.
- pull oneself by one's bootstraps — a loop of leather or cloth sewn at the top rear, or sometimes on each side, of a boot to facilitate pulling it on.
- put something on the long finger — to postpone something for a long time
- reduced instruction set computer — (processor) (RISC) A processor whose design is based on the rapid execution of a sequence of simple instructions rather than on the provision of a large variety of complex instructions (as in a Complex Instruction Set Computer). Features which are generally found in RISC designs are uniform instruction encoding (e.g. the op-code is always in the same bit positions in each instruction which is always one word long), which allows faster decoding; a homogenous register set, allowing any register to be used in any context and simplifying compiler design; and simple addressing modes with more complex modes replaced by sequences of simple arithmetic instructions. Examples of (more or less) RISC processors are the Berkeley RISC, HP-PA, Clipper, i960, AMD 29000, MIPS R2000 and DEC Alpha. IBM's first RISC computer was the RT/PC (IBM 801), they now produce the RISC-based RISC System/6000 and SP/2 lines. Despite Apple Computer's bogus claims for their PowerPC-based Macintoshes, the first RISC processor used in a personal computer was the Advanced RISC Machine (ARM) used in the Acorn Archimedes.
