1945 The “Memex” concept & 1949- The Birth of the Modem

 In 1945 the Memex concept was adopted. The imaginary Memex desk is meant to let a user compare and create links between microfilm documents, somewhat like today’s clickable Web links and bookmarks with side-by-side screens. The idea is that people will continually build on each other's associative trails through the world's knowledge, helping tackle the growing problem of information overload. The Memex is the brainchild of top U.S. scientist Vannevar Bush, an analog computing pioneer who had helped oversee the atomic bomb's development. The basic mechanism he suggests is a microfilm automatic selector similar to those built by optics pioneer Emmanuel Goldberg in the early 1930s. Bush publicizes the Memex concept in 1945 articles in The Atlantic Monthly and Life. In most recent times for the memex concept was brought to the light on a TV show where they used it in a different in order to search for something or someone they were looking for.

In 1949 the one thing that we still use highly across the world was born, and that is the birth of the modem.Computers “talk” over ordinary voice phone lines through modems. Developed in 1949 for transmitting radar signals by Jack Harrington’s group at the Air Force Cambridge Research Center (AFCRC) near Boston, the modem modulates digital data into sounds and demodulates received sounds into digital data. (MODulation + DEModulation = MODEM). Modems will be adapted to computers in 1953 for the upcoming SAGE system and commercialized by Bell Telephone in 1958. By letting computers use normal voice telephone lines, they offer greater coverage and lower costs than dedicated telegraph or leased data lines.

Both of the things that have been mention have helped all types of people and all types of different hardware, or should I say networks. The modem for sure has been the one that has helped me the most because without a modem I problem wouldn't have internet depending on what it is that I am doing, almost everything that we as humans have nowadays has some modem that is collecting information from somewhere and sending it to another modem that is being used with another computer.
