It is called the "Model K" because the "K" in the name means that he made it in his "Kitchen."]]> 2021-04-08 15:24:08 UTC https://padlet.com/26len/wxzgl2y1p6tmp7s5/wish/1396373944 26len https://padlet.com/26len/wxzgl2y1p6tmp7s5/wish/1396411647 In 1940, Stibitz introduced the (CNC) at an American Mathematical Society conference at Dartmouth College. Stibitz impressed the group by displaying calculations remotely on the CNC that is located in New York City using a Teletype terminal connected to New York over special telephone lines.]]> 2021-04-08 15:31:47 UTC https://padlet.com/26len/wxzgl2y1p6tmp7s5/wish/1396411647 26len https://padlet.com/26len/wxzgl2y1p6tmp7s5/wish/1396437125 Researchers Frederic Williams, Tom Kilburn, and Geoff Toothill invent the Small-Scale Experimental Machine (SSEM), but people liked to call it the Manchester Baby. The (SSEM) was built to test a new memory technology which was the first high-speed electronic random access memory for computers.]]> 2021-04-08 15:37:00 UTC https://padlet.com/26len/wxzgl2y1p6tmp7s5/wish/1396437125 26len https://padlet.com/26len/wxzgl2y1p6tmp7s5/wish/1396467355 The first large-scale computer communications network, SAGE connects 23 hardened computer sites in the US and Canada.
