Prime95 is a popular freeware application that is primarily used for stress testing and benchmarking computer hardware, particularly CPUs and RAM. Developed by George Woltman, the program utilizes the Lucas-Lehmer primality test to search for Mersenne prime numbers, which are prime numbers that can be expressed in the form of 2^p - 1, where p is also a prime number.
