Discrete simulation systems records events at regular time intervals when a simulation component generates output. Continuous simulation systems record events on a nearly continuous basis, using a relatively small time unit between event recordings. Discrete simulation is usually faster while still providing an accurate picture of the system's behavior.

In continuous simulation systems, time is treated as a continuous variable, allowing for modeling of systems with continuous or fluid-like behavior. In discrete simulation systems, time is represented in discrete steps, making it suitable for modeling systems that operate in a step-by-step manner with distinct events. Continuous simulation systems require solving differential equations, while discrete simulation systems involve tracking the state changes based on discrete event occurrences.
Quantization error is the difference between the actual analog signal and the quantized digital representation of that signal. It occurs when an analog signal is converted into a digital form by rounding off the signal values to the nearest available digital value. This error can introduce inaccuracies in the signal representation.
Different elements have different line spectra because each has a unique arrangement of energy levels for its electrons. When electrons transition between these energy levels, they emit or absorb specific wavelengths of light, creating distinct lines in the spectrum. This results in discrete lines rather than a continuous spectrum.
Continuous lasers emit a continuous beam of light, while pulsed lasers emit light in short bursts or pulses. Continuous lasers are used for applications requiring steady illumination, while pulsed lasers are used for applications requiring high peak power in a short duration.
A simulation is a computer-generated model that mimics real-world processes, such as radioactive decay, using mathematical algorithms. Actual radioactive decay is a natural process where unstable atomic nuclei lose energy by emitting radiation. While simulations provide insight into how radioactive decay works, real decay occurs spontaneously and cannot be controlled or manipulated like in a simulation.
Flow refers to the movement of a substance in a continuous and smooth manner, while motion refers to the act of changing position or location. Flow typically involves a continuous stream of particles, such as a liquid or gas, moving in a particular direction, whereas motion can involve an object changing its position or posture.
