...HISTORY OF THE COMPUTER ARTICLE WRITTEN BY: ADEBOWALE ONIFADE ELECTRICAL ELECTRONIC ENGINEERING DEPARTMENT UNIVERSITY OF IBADAN NIGERIA REGION 8 HISTORY OF THE COMPUTER ABSTRACT This paper takes a keen look at the history of computer technology with a view to encouraging computer or electrical electronic engineering students to embrace and learn the history of their profession and its technologies. Reedy (1984) quoted Aldous Huxley thus: “that men do not learn very much from the lessons of history is the most important of all the lessons that history has to teach.” This paper therefore emphasizes the need to study history of the computer because a proper study and understanding of the evolution of computers will undoubtedly help to greatly improve on computer technologies.

Today, the word computer refers to computing devices, whether or not they are electronic, programmable, or capable of ‘storing and retrieving’ data...
