Introduction In the digital age, the functionality of computer networks hinges on the ability to move data reliably and efficiently from one point to another. As outlined in standard technical resources such as Computer Networks by J.S. Katre, the physical foundation of all networking lies in "Data Transmission." This process involves the transfer of data—in the form of electromagnetic signals—over a transmission medium. Understanding data transmission requires an analysis of the relationship between data and signals, the distinction between analog and digital methodologies, and the various modes in which this communication occurs.
