GEE-LIE LIVING IN THE IT ERA (FOUR BASIC COMPUTER PERIODS).pdf
The Four Basic Periods of Computer History
The four basic periods of computer history can be divided into the following:
Pre-mechanical Age – it involves the basic system of writing and alphabets like petroglyphs, ideographs, cuneiforms, the invention of pen and paper, and the first calculator ‘abacus’.
Mechanical Age – it involves the start of the information explosion where machines are now helping with the creation and transmission of information through a wider audience than in the pre-mechanical age.
Electromechanical Age – this is the start of telecommunications. Telegraphs, telephone, and radio are the highlights of this age.
Electronic Age – this is where we are today where computers are programmable and electric.
Evolution3
Computer evolution began with early humans using tools like fingers, stones, and marks to calculate and has progressed through various eras and generations of increasingly advanced technologies. Early ancient devices included the abacus, Napier's bones, and the slide rule. Mechanical computers then provided more advanced calculation abilities. The electronic era began in 1946 and has progressed from vacuum tubes to transistors to integrated circuits and now includes artificial intelligence and future possibilities like molecular computers. The future of computing continues to expand capabilities but also raises questions about its threats and our readiness for further advancement.
