**Algebraic number field**— In mathematics, an algebraic number field (or simply number field) F is a finite (and hence algebraic) field extension of the field of rational numbers Q. Thus F is a field that contains Q and has finite dimension when considered as a vector… …63

**Prime number theorem**— PNT redirects here. For other uses, see PNT (disambiguation). In number theory, the prime number theorem (PNT) describes the asymptotic distribution of the prime numbers. The prime number theorem gives a general description of how the primes are… …64

**Pseudorandom number generator**— A pseudorandom number generator (PRNG), also known as a deterministic random bit generator (DRBG),[1] is an algorithm for generating a sequence of numbers that approximates the properties of random numbers. The sequence is not truly random in… …65

**Hardware random number generator**— This SSL Accelerator computer card uses a hardware random number generator to generate cryptographic keys to encrypt data sent over computer networks. In computing, a hardware random number generator is an apparatus that generates random numbers… …66

**Copy-number variation**— This gene duplication has created a copy number variation. The chromosome now has two copies of this section of DNA, rather than one. Copy number variations (CNVs) a form of structural variation are alterations of the DNA of a genome that results …68

**Computable number**— In mathematics, particularly theoretical computer science and mathematical logic, the computable numbers, also known as the recursive numbers or the computable reals, are the real numbers that can be computed to within any desired precision by a… …69

**Special number field sieve**— The special number field sieve (SNFS) is a special purpose integer factorization algorithm. The general number field sieve (GNFS) was derived from it.The special number field sieve is efficient for integers of the form r e plusmn; s , where r and …70
