Communication has come a long way from the days of telegrams and radio waves. Nowadays, we rely heavily on copper wires and optic fibers for our modern gadgets and data encryption. Unlike the bare copper wires of the past, today’s wires are equipped with insulations and alloyed metal sheaths for better accuracy and safety. The number of insulation layers and the type of materials used play a crucial role in ensuring safety. However, impurities can still pose a challenge, affecting accuracy and causing signal disruptions.
