  • manchester encoding — (communications, protocol)   A method of transmitting bits which enables the receiver to easily synchronise with the sender. A simple way of signalling bits might be to transmit a high voltage for some period for a 1-bit and a low voltage for a 0 bit: Bits Sent: 1 1 0 0 Signal: High ___ Low |___ Time: -> . . . . . However, when several identical bits are sent in succession, this provides no information to the receiver about when each bit starts and stops. Manchester encoding splits each bit period into two, and ensures that there is always a transition between the signal levels in the middle of each bit. This allows the receiver to synchronise with the sender. In normal Manchester encoding, a 1-bit is transmitted with a high voltage in the first period, and a low voltage in the second, and vice verse for the 0 bit: Bits Sent: 1 1 0 0 Signal: High Low || |_| || Time: -> . ' . ' . ' . ' . In Differential Manchester encoding, a 1-bit is indicated by making the first half of the signal equal to the last half of the previous bit's signal and a 0-bit is indicated by making the first half of the signal opposite to the last half of the previous bit's signal. That is, a zero bit is indicated by a transition at the beginning of the bit. Like normal Manchester encoding, there is always a transition in the middle of the transmission of the bit. Differential Manchester Encoding Bits Sent: 1 1 0 0 Signal: High __ Low |_| || || Time: -> . ' . ' . ' . ' . With each bit period half as long, twice as much bandwidth is required when using either of the Manchester encoding schemes.

  • pretty good privacy — (tool, cryptography)   (PGP) A high security RSA public-key encryption application for MS-DOS, Unix, VAX/VMS, and other computers. It was written by Philip R. Zimmermann <[email protected]> of Phil's Pretty Good(tm) Software and later augmented by a cast of thousands, especially including Hal Finney, Branko Lankester, and Peter Gutmann. PGP was distributed as "guerrilla freeware". The authors don't mind if it is distributed widely, just don't ask Philip Zimmermann to send you a copy. PGP uses a public-key encryption algorithm claimed by US patent #4,405,829. The exclusive rights to this patent are held by a California company called Public Key Partners, and you may be infringing this patent if you use PGP in the USA. This is explained in the PGP User's Guide, Volume II. PGP allows people to exchange files or messages with privacy and authentication. Privacy and authentication are provided without managing the keys associated with conventional cryptographic software. No secure channels are needed to exchange keys between users, which makes PGP much easier to use. This is because PGP is based on public-key cryptography. PGP encrypts data using the International Data Encryption Algorithm with a random session key, and uses the RSA algorithm to encrypt the session key. In December 1994 Philip Zimmermann faced prosecution for "exporting" PGP out of the United States but in January 1996 the US Goverment dropped the case. A US law prohibits the export of encryption software out of the country. Zimmermann did not do this, but the US government hoped to establish the proposition that posting an encryption program on a BBS or on the Internet constitutes exporting it - in effect, stretching export control into domestic censorship. If the government had won it would have had a chilling effect on the free flow of information on the global network, as well as on everyone's privacy from government snooping.
  • programmer's switch — (hardware)   A button on the front of some Apple Macintosh computers which, when pressed, causes a command line prompt to appear. This gives access to the built-in mini-debugger, which has commands to dump memory, return to the application that was broken out, and others. A more sophisticated debugger must be installed in order to inspect breakpoints, etc.
  • psychotechnological — of or relating to psychotechnology
  • quick-change artist — a person adept at changing from one thing to another, as an entertainer who changes costumes quickly during a performance.
  • rayleigh scattering — the scattering of light by particles that are very small in relation to the wavelength of the light, and in which the intensity of the scattered light varies inversely with the fourth power of the wavelength.
  • recording secretary — an officer charged with keeping the minutes of meetings and responsible for the records.
  • register allocation — (compiler, algorithm)   The phase of a compiler that determines which values will be placed in registers. Register allocation may be combined with register assignment. This problem can be shown to be isomorphic to graph colouring by relating values to nodes in the graph and registers to colours. Values (nodes) which must be valid simultaneously are linked by edges and cannot be stored in the same register (coloured the same). See also register dancing and register spilling.
  • religious education — religion as school subject
