I spent a couple of weeks in Rosslyn, Virginia, on vacation, and stumbled across a sign identifying the site of the building where the U.S. Defense Department’s Advanced Research Projects Agency (ARPA) invented the network and first attendant protocols, ARPANet, that are today known as the Internet. I photographed the sign and uploaded it to Mapillary, which for some reason has placed it incorrectly (I’m trying to move it to the correct location but Mapillary advises it “may take some time.”)

Can anybody tell me what the binary code on the back of the sign means?
