Answer:
WWII; Manhattan Project.
Explanation:
Computer simulation refers to a mathematical model designed and developed to predict the outcome or behavior of a hypothetical or real-life scenario on a computer system, so as to illustrate and understand how the system functions.
Historically, computer simulations were first developed during World War II (WWII) as a part of the Manhattan Project.
For example, SimpleScalar refers to a computer architectural simulating software application or program which was designed and developed by Todd Austin at the University of Wisconsin, Madison, United States of America. It is an open source simulator written with "C" programming language and it's used typically for modelling virtual computer systems having a central processing unit (CPU), memory system parameters (hierarchy), and cache.
