Internet’s 50th birthday. Image: wikimedia
October 29, 1969. Neil Armstrong had recently stepped onto another world: the moon. That same year, another new world was born. UCLA, Stanford, the University of California-Santa Barbara, and the University of Utah were working on ARPANET (Advanced Research Projects Agency Network). Graduate student Charley Kline sent a computer message from UCLA to Bill Duvall at Stanford, typing the word “Login.” The system crashed; but the letters ‘L’ and ‘O’ transmitted. Leonard Kleinrock, professor of computer science at UCLA, helped to complete the message about an hour later
Now, we’re moving into 5G. 1G was analog cellular; 2G was CDMA and GSM digital. 3G technologies like EVDO were faster; 4G LTE was even faster. 5G will deliver three changes: faster speed (moving more data); lower latency (optimizing response); ability to connect multiple devices. 5G might help autonomous vehicles become more accurate; smart roads will become more responsive, too. 5G will enable Virtual Reality (VR) and instant transmission.
The internet was born fifty years ago today. Since then, complex transmissions have spread science around the world, and a few chats, too. But some might opine that the first two letters ever sent best expressed the wonder: “‘Lo,’ and Behold.”
