Exponential FunctionA mathematical function where some constant base is raised to a variable power. These tend to grow very quickly after a certain point.FlopsThe number of floating point operations per second that a computational device can perform. A typical measure of the power of a device to perform calculations.Law of Accelerating ReturnsThe idea that the rate of change itself tends to increase exponentially with regards to technology.Logic GateAn electrical circuit that produces output as determined by the corresponding logic table.Logic TableA tool used to determine the output of a logic function given all of its potential input combinations.Monte Carlo MethodRunning a stochastic simulation many times under all desired combinations of input parameters in order to obtain results that have good statistical reliability.Moore's LawThe prediction of Gordon Moore that the number of transistors on integrated circuits doubles about every 18 months.ParameterizationThe process of choosing values for the parameters in a model.PinoutA diagram describing the function of each lead on an integrated circuit's casing.Simulation and ModelingA subfield of computer science concerned with describing natural phenomena using models composed of algorithms and equations and observing the behavior of these models in simulations.StochasticA simulation that incorporates elements of randomness and unpredictability.TransientIn simulation, a state in which a model may seem stable for an amount of time before major changes occur.TransistorA discrete electronic component that has been historically important to the development of computers. They function primarily as switches.TTLTransistor-transistor logic is an alternative to CMOS used to construct circuits. They tend to be slower but easier to design with than CMOS.ValidationEnsuring that a model has sufficiently accurate predictive powers within the given problem domain.VerificationChecking to make sure that a model is correctly implemented with respect to its design.VLSIVery-large-scale integration is a manufacturing technique by which many thousands of transistors are combined into a single chip.
