Major achievements to a computer technology

Time has seen significant improvements in the usability and effectiveness of computing technology. Modern society has seen a significant shift in the users of computer technology, from usage only by experts and professionals, to a near-ubiquitous user base. Initially, computers were quite costly, and some degree of human aid was needed for efficient use — in part from professional computer operators. As computer adoption became more widespread and affordable, less human assistance was needed for common usage.
Major achievements
The German military used the Enigma machine during World War II for communication they thought to be secret. The large-scale decryption of Enigma traffic at Bletchley Park was an important factor that contributed to Allied victory in WWII.
Despite its short history as a formal academic discipline, computer science has made a number of fundamental contributions to science and society — in fact, along with electronics, it is a founding science of the current epoch of human history called the Information Age and a driver of the Information Revolution, seen as the third major leap in human technological progress after the Industrial Revolution and the Agricultural Revolution.
These contributions include:
The start of the «digital revolution,» which includes the current Information Age and the Internet. A formal definition of computation and computability, and proof that there are computationally unsolvable and intractable problems. The concept of a programming language, a tool for the precise expression of methodological information at various levels of abstraction.
In cryptography, breaking the Enigma code was an important factor contributing to the Allied victory in World War II.
Image synthesis, including video by computing individual video frames.
Simulation of various processes, including computational fluid dynamics, physical, electrical, and electronic systems and circuits, as well as societies and social situations along with their habitats, among many others. Modern computers enable optimization of such designs as complete aircraft. Notable in electrical and electronic circuit design are SPICE, as well as software for physical realization of new designs. The latter includes essential design software for integrated circuits. Scientific computing enabled practical evaluation of processes and situations of great complexity, as well as experimentation entirely by software. It also enabled advanced study of the mind, and mapping of the human genome became possible with the Human Genome Project.
Algorithmic trading has increased the efficiency and liquidity of financial markets by using artificial intelligence, machine learning, and other statistical and numerical techniques on a large scale to a great level phenomena.
