The first definition of simulation is an imitation of the operation of a real-world process or system. However this term is more complex than just this one definition. Simulation in fact can also be related to abstraction, simulacra, and feign.
The general definition of abstraction is the process of forming a concept by identifying common features among a group of individuals, or by ignoring unique aspects of these individuals. This concept is subjective since each individual perceives the world in a different way and has different impact that could affect its mindset.
Simulacra or simulacrum is the actual representation or imitation of a person or thing. It can also be defined as “an image without resemblance” (Gilles Deleuze, 1990). The concept of simulacra is connected to the hyperreal that the philosopher Jean Baudrillard defined as “more real than real” in which something fake comes to be more definitive than reality itself.
The last concept is feigning which can simply be defined as faking. However from the understanding of the text Simulacra and Simulations by Jean Baudrillard “to simulate is not simply to feign: someone who feigns an illness can simply go to bed and pretend he is ill. Someone who simulates an illness produces in himself some of the symptoms”. Therefore feigning can be defined as masking, while simulation threatens the difference between what is considered “true” and “false”, between what is “real” and “imaginary”.
We can therefore create a difference between simulation and representation. Representation is about the principle in which the feigning and the real are equivalent. On the other hand simulation is about the negation of the sign as value and the sign as a death sentence of every reference.
