# Instantiation **Instantiation** is the process of bringing something into being or realizing it in a specific form. When the program is executed (run) on the computer, the [Encoded](Encoding.md) instructions are read and processed by the CPU and other hardware components. This process causes the simulation to come to life, generating visual and auditory output that the user experiences as a virtual flight. The instantiation is the actual running of the program, where the encoded rules and data are used to create the dynamic, interactive simulation. Instantiation is always [Physical](Physical.md)—[Computation is a Physical Process](Computation%20is%20a%20Physical%20Process.md), and is thus *dynamic*. --- Date: 20250220 Links to: Tags: References: * []()
