A passenger name record (PNR) is a record in the database of a computer reservation system (CRS) that contains the itinerary for a passenger or a group of passengers travelling together. The concept of a PNR was first introduced by airlines that needed to exchange reservation information in case passengers required flights of multiple airlines ...
When a reservation is made, a passenger name record (PNR) is created in the computer reservation system (CRS) used by the person making the booking, and the CRS will automatically generate a record locator for the PNR. If the only flight(s) are operated by the airline on which the booking is being made, then only one PNR will exist.
The Agreement between the United States of America and the European Union on the use and transfer of Passenger Name Records to the United States Department of Homeland Security is an international agreement between the United States of America and the European Union that was signed on 14 December 2011 for the purpose of providing passenger name records (PNR) from air carriers operating ...
A reservation for an itinerary is made in the airline system, either directly by the passenger or by an agent. The itinerary includes all the above details needed for the issuance of an air ticket, except the ticket number. When the reservation is made, a passenger name record (PNR) will be created which is used to manage the reservation and ...
A pseudo-noise code (PN code) or pseudo-random-noise code (PRN code) is one that has a spectrum similar to a random sequence of bits but is deterministically generated. The most commonly used sequences in direct-sequence spread spectrum systems are maximal length sequences, Gold codes, Kasami codes, and Barker codes.

Peak signal-to-noise ratio (PSNR) is an engineering term for the ratio between the maximum possible power of a signal and the power of corrupting noise that affects the fidelity of its representation.
A pseudorandom number generator (PRNG), also known as a deterministic random bit generator (DRBG), [1] is an algorithm for generating a sequence of numbers whose properties approximate the properties of sequences of random numbers.
