The Mersenne Twister is a general-purpose pseudorandom number generator (PRNG) developed in 1997 by Makoto Matsumoto (松本 眞) and Takuji Nishimura (西村 拓士). [1] [2] Its name derives from the choice of a Mersenne prime as its period length.
A telephone exchange name or central office name was a distinguishing and memorable name assigned to a central office. It identified the switching system to which a telephone was connected, and facilitated the connection of telephone calls between switching systems in different localities.
Random number generators are important in many kinds of technical applications, including physics, engineering or mathematical computer studies (e.g., Monte Carlo simulations), cryptography and gambling (on game servers).
Caller ID spoofing is a spoofing attack which causes the telephone network's Caller ID to indicate to the receiver of a call that the originator of the call is a station other than the true originating station. This can lead to a display showing a phone number different from that of the telephone from which the call was placed.

Pseudorandomness. A pseudorandom sequence of numbers is one that appears to be statistically random, despite having been produced by a completely deterministic and repeatable process. [1] Simply put, the problem is that many of the sources of randomness available to humans (such as rolling dice) rely on physical processes not readily available ...
