(Introduction)
Computer science is the scientific pillar of today’s modern era on which the entire digital world stands. This knowledge is not limited to the use of computers or programming, but is the name of a collection of deep studies of human intelligence, logic, mathematics, engineering, psychology, society, security, robotics, artificial intelligence and data. Computer science is the knowledge that teaches us How a machine can think, understand data, avoid mistakes, and make the world more efficient, safer, and more accessible.
Every major technology in the world — whether it’s mobile phones, the internet, space science, artificial intelligence (AI), social media, digital currency, virtual reality, or autonomous vehicles — is based on computer science.

Literature Review
There is a large body of research on computer science worldwide. The basic ideas of computing were introduced by mathematicians, logicians, and statisticians at the beginning of the 20th century. A review of the literature identifies the following major stages:
Early theories
Charles Babbage’s concept of the “Analytical Engine” laid the foundation for the basic architecture of the computer.
Ada Lovelace gave the initial concept of “programming” which became part of the first definition of computer science.
Alan Turing and computational theories
Alan Turing’s “Turing Machine” and “Computability” principles clarified what problems a machine can solve and what its limitations are. The entire modern computing system is built on this foundation.
Modern programming and data structures
John Bowden, Donald Kunth, and other researchers developed algorithms, data structures, and programming languages on a scientific basis.
Internet and Networking
The research of Wint Krafft and Robert Kahn created the TCP/IP protocol, which became the foundation for the world’s Internet.
Artificial intelligence research
John McCarthy introduced the concept of “Artificial Intelligence” in 1956.
Subsequently, a lot of research was done in deep learning, neural networks, and machine learning, which brought AI to a practical level.
