This is the Antikythera mechanism, which is considered the first mechanical analog computer, dating back to the first century BC.. Ideas of computer science were first mentioned before the 1950s under the Massachusetts Institute of Technology (MIT) and Harvard University, where they had discussed and began thinking of computer circuits and numerical calculations.

An accompanying book, The Computer Book, was commissioned by the BBC to tie in with the series, [4] giving an introduction to microcomputers and general computing. Its content covers the basics of the history of computing , programming languages , debugging , logic programming , semiconductor memory , printing , ADCs / DACs , flowcharts , as ...
Fog computing is a viable alternative to prevent such a large burst of data flow through the Internet. [149] The edge devices ' computation power to analyze and process data is extremely limited. Limited processing power is a key attribute of IoT devices as their purpose is to supply data about physical objects while remaining autonomous.
