History of Computer Networks In 1960, the ARPANET (Advanced Research Projects Agency Network) was widely recognized as the world’s first operational packet-switching computer network and the foundational technology of the modern internet. Developed By: The U.S. Department of Defense’s Advanced Research Projects Agency (ARPA, now DARPA). First Operational: 1969. Key Milestone: The first successful message transmission occurred on October 29, Read more…
Modulation (Click this Link for the difference between Modulation & Encoding) Introduction of Modulation As we know that in normal communication, signals lose their strength/energy slowly as they travel medium up to large distances. To send these transmitting message signals effectively for long distances, we use the modulation technique. At Read more…
