Charles Babbage - Analytical Engine
The analytical engine was a proposed mechanical general-purpose computer designed by English mathematician and computer pioneer Charles Babbage. It was first described in 1837 as the successor to Babbage's difference engine, which was a design for a simpler mechanical calculator. -
Herman Hollerith - Punch Cards
At the end of the 1800s At the end of the 1800s Herman Hollerith invented the recording of data on a medium that could then be read by a machine, dubious - discuss developing punched card data processing technology for the 1890 U.S. census. -
Alan Turing - Turing Machine
The Turing machine was invented in 1936 by Alan Turing, who called it an "a-machine" (automatic machine). A Turing machine is a mathematical model of computation describing an abstract machine that manipulates symbols on a strip of tape according to a table of rules. Despite the model's simplicity, it is capable of implementing any computer algorithm. -

WiFi
Wi-Fi, networking technology that uses radio waves to allow high-speed data transfer over short distances. Eventually, a committee of industry leaders came up with a common standard, called 802.11, which was approved by the Institute of Electrical and Electronics Engineers (IEEE) in 1997. -
iPhone
The original Apple iPhone incorporated a 3.5-inch multi-touch display with few hardware buttons, and ran the iPhone OS operating system with a touch-friendly interface, then marketed as a version of Mac OS X. It launched on June 29, 2007, at a starting price of US$499 in the United States, and required a two-year contract with AT&T. -
Chromebook
