2. Checksum - Wikipedia

   en.wikipedia.org/wiki/Checksum

   The simplest checksum algorithm is the so-called longitudinal parity check, which breaks the data into "words" with a fixed number n of bits, and then computes the bitwise exclusive or (XOR) of all those words. The result is appended to the message as an extra word. In simpler terms, for n =1 this means adding a bit to the end of the data bits to guarantee that there is an even number of '1's ...

3. Moore machine - Wikipedia

   en.wikipedia.org/wiki/Moore_machine

   In the theory of computation, a Moore machine is a finite-state machine whose current output values are determined only by its current state. This is in contrast to a Mealy machine, whose output values are determined both by its current state and by the values of its inputs. Like other finite state machines, in Moore machines, the input typically influences the next state. Thus the input may ...

4. Biometric device - Wikipedia

   en.wikipedia.org/wiki/Biometric_device

   Iris scanner in action to identify people. A biometric device is a security identification and authentication device. Such devices use automated methods of verifying or recognising the identity of a living person based on a physiological or behavioral characteristic. These characteristics include fingerprints, facial images, iris and voice ...

5. Turing machine - Wikipedia

   en.wikipedia.org/wiki/Turing_machine

   A Turing machine that is able to simulate any other Turing machine is called a universal Turing machine (UTM, or simply a universal machine). Another mathematical formalism, lambda calculus, with a similar "universal" nature was introduced by Alonzo Church. Church's work intertwined with Turing's to form the basis for the Church–Turing thesis. This thesis states that Turing machines, lambda ...

6. Verification and validation of computer simulation models

   en.wikipedia.org/wiki/Verification_and...

   Verification and validation of computer simulation models is conducted during the development of a simulation model with the ultimate goal of producing an accurate and credible model. [1] [2] "Simulation models are increasingly being used to solve problems and to aid in decision-making. The developers and users of these models, the decision makers using information obtained from the results of ...

7. Proof assistant - Wikipedia

   en.wikipedia.org/wiki/Proof_assistant

   Proof assistant. In computer science and mathematical logic, a proof assistant or interactive theorem prover is a software tool to assist with the development of formal proofs by human-machine collaboration. This involves some sort of interactive proof editor, or other interface, with which a human can guide the search for proofs, the details ...
