Digital Transmission in Computer Network

A type of signal transmission known as "digital transmission" involves the discrete time variation of two values, one of which represents the binary number "0" and the other "1." Voltage or electrical potential is often the variable amount in copper cabling. Fiber-optic wiring or wireless communication use variations in intensity or any other physical quantity. Digital signals use discrete values to transmit binary data through a communication path like a network cable or a telecommunications link. On a serial transmission line, a digital signal is transmitted one bit at a time. Analog and digital methods can both be used to store data or information.
