History and Development of Computer Science

The development root of Computer Science relates to some distinguishable fields, which are:

Mathematics: It gave the notions and introduced the concept of 'binary number system' and 'stored program'. It was understood that we could represent the information in the form of zeros and ones and store them in the system.
Physics and Electrical Engineering: It stroked Boolean algebra's idea for circuit design, where it became possible to produce arbitrary outputs (false or true) by combining the inputs of electrical impulses to a circuit by Boolean algebra. It became possible to design a circuit with binary value inputs and get the desired combination of 0's and 1's as its output. Hence, the invention of the transistor, invention of optical, electronic, and magnetic media for the transmission and storage of information came into existence.
Management information systems: These systems are known as Data processing systems that describe the method of processing the data. It led to the notion and evolution of concepts such as fetching information, searching, sorting, databases, and GUIs (Graphical User Interfaces.

All these fields led to the development of Computer Science.

1623: A scientist named Wilhelm Schickard designed and constructed the mechanical computer, the first working calculator.

1673: Gottfried Leibniz demonstrated a digital mechanical calculator known as Stepped Reckoner. Gottfried Leibniz was considered as the first computer scientist and information theorist.

1820: Thomas de Colmar invented Arithmometer, the first strong and reliable calculating machine to be used in offices for daily purposes. With this, he also launched the industry of mechanical calculator.

1822: Charles Babbage began to design the Difference Engine (the first automated mechanical calculator), which gave rise to the idea of Analytical Engine. The Analytical engine was the first programmable mechanical calculator. In 1834, he began to develop the Analytical Engine, and within two years, he sketched many salient features of the modern computer.

1843: Ada Lovelace translated and wrote a French article on Analytical Engine in which she published the algorithm to compute the Bernoulli numbers. It was considered the first published algorithm to be implemented on a computer.

1885: Tabulator was invented by Herman Hollerith, in which he used punched cards for processing the statistical information. With this, Herman's company became part of IBM.

1937: Howard Aiken initiated the ASCC/Harvard Mark me (known as the giant programmable calculator) after convincing IBM to develop it. The giant calculator was based on the Charles Analytical Engine. The ASCC/Harvard Mark I was able to use punched cards and CPU (Central Processing Unit) on its own. It was believed that after 100 years of impossible Babbage's dream, it had become possible, and the dream came true.

1940: The ENIAC and Atanasoff-Berry computer, which was known as the new and more powerful computing machines, were developed. The term 'computer' referred to the machines and their working. It was proved that more than calculations, computers could be used for other computation works also. The field of Computer Science was broadened to the study of computation.

1945: IBM (International Business Machines) founded the Watson Scientific Computing Laboratory at Columbia University, New York.

1950 and 1960: In this period, Computer Science started to establish as a distinct academic discipline.

1953: At the University of Cambridge Computer Laboratory, the Cambridge Diploma in Computer Science began. The diploma was the world's first computer science degree program. On the other side, the first transistorized computer was built by the University of Manchester. The transistorized computer was known as the Transistor Computer.

1962: The first department of Computer Science was formed in the Purdue University, United States.

1959: Mohamed Atalla and Dawon Kahng invented the MOSFET or MOS, i.e., metal-oxide-silicon field-effect transistor at Bell Labs. MOS was the first truly compact transistor which could be miniaturized and mass-produced for wide uses. It became possible to build high-density integrated circuit chips known as the computer or microcomputer revolution.

Etymology of Computer Science

In 1959, the term 'computer science' appeared in an article in Communication of the ACM for the first time. The writer Louis Fein in the article argued for the creation of a Graduate School in Computer Sciences. Finally, in 1962, the writer's efforts, including the efforts of numerical analyst George Forsythe were rewarded. Hence, universities began to create the departments of Computer Science, and the creation started at Purdue. A Danish scientist Peter Naur suggested terms 'Datalogy' and 'Data Science'. In 1969, the University of Copenhagen became the first scientific institution to use the term in its 'Department of Datalogy', and Peter Naur became the first professor in Datalogy. Numerous terms for the computing field were suggested to the practitioners in the Communication of the ACM. These names were flow-charts-man, turologist, turingineer, applied meta-mathematician, applied epistemologist. After three months, ACM also suggested the term Comptologist, then the hypologist, and then Computics was suggested. Computer Science was supposed to have a close relationship with maths because computer science was highly influenced by the work of Mathematicians like Alan Turing and many other personalities. Later on, the bond between computer science and software engineering came as an issue. In this dispute, David Parnas claimed that the objective of studying computer science is the properties of computation, and on the other hand, the objective of studying software engineering is the designing of specific computations for fulfilling the practical goals. Hence, it was seen that the academic, funding, and political aspects of it became dependent on whether to form mathematics emphasized department or engineering emphasized department. Finally, both the departments made efforts to bridge the computer science field educationally all over the globe.
