Computer Data Processing

Computer science is the science that deals with the theory, design and application of information processing systems. Its beginnings date back to the first electronic computer, the Electrical Numerical Integrator and Computer (ENIAC), started in 1946 in U. of Pennsylvania.

During the 1950s, four main fields of interest emerged. The first is the “hardware” – efficient equipment manufacturing with faster CPUs, higher capacity memory and more input and output devices to solve complexity problems. growing. Another field covers “operating software” – programming languages ​​- and the logical structures and workflows required to run the hardware and other programs.

These software and hardware systems are rapidly expanding the scope of applications, which is the third area of ​​research and development. The first applications focus on MATHEMATICS then science and engineering, then business and social sciences, and finally most fields of activity.

As these three areas develop, theorists study algorithms (process descriptions) expressed in language that can be understood by computers. This fourth field of study, “the theory of treatment”, questions what algorithms need to be effective and tries to find them in a variety of contexts. Alan Turing, instigator of the theory, has identified mathematical computability to the ability of a primitive computer to stop the execution of a program.

During the 1960s, as discoveries in these fields accumulated, computer science appeared in several universities as a separate discipline separate from the departments of mathematics and electrical engineering, as well as data processing services with which it was involved. was previously associated. Formal curricula are developed, and courses in data structure, programming languages ​​and processing theory serve as starting points for computer scientists.
