Detailed explanation-1: -At its most simplistic, data sent over a cable is converted into binary code – a collection of 1s and 0s. The device transmitting the data will send current along the cable at two different voltages (for instance, 0V and 5V), with one voltage representing 1s and the other 0s.
Detailed explanation-2: -A copper Ethernet cable works by sending electrical currents up and down the copper wire from one device to another. Today, the most common copper cables are Cat5e, Cat6, and Cat6a. Cat5e cables are arguably the most universal cable that will work with most network setups.
Detailed explanation-3: -Coaxial cable and twisted pair cable are copper or copper-based wire surrounded by insulation with other materials. Both of them can transmit television, telephone and data with electrical signals.
