In 1941 the first computer was created and in 1969 the Internet was born. We move on to the era when computers and the rise of the Internet began to be used. The switchboard technology arrived in Europe in 1898, after several improvements. Its introduction was a great success, although it did not please the operators, who would lose their jobs. In November 1891, the first automatic telephone switchboard for 99 subscribers was installed in Indiana, specifically in La Porte. This invention came about because he realized that one of the operators was forwarding calls to the competition, so he wanted to avoid forwarding calls manually and that they could listen to private conversations. Now we go back to 1889 when Almon Brown Strowger invented the automatic telephone switchboard with 21 subscribers. In this way, the person making the telephone call was actually contacting the switchboard first, which plugged the plug into the socket corresponding to the person receiving the call. The distribution of calls was done by operators (almost always women) who were in charge of connecting the network plugs to the corresponding sockets. The first manual telephone switchboard was found in the United States in 1878, at that time it was the only possible method and the switchboards had to be manual. Its use was a major step forward for worldwide communication and globalization began to expand at a faster pace. More than 160 years ago, Antonio Meucci invented the telephone and it was only in 1876 that Alexander Graham Bell patented it.
