The Last Analog Hour
A staple of the "Data Transmission" chapter in these PDFs is the classification of communication directions:
Finally, the physical implementation of data transfer is divided into serial and parallel transmission. Parallel transmission transmits multiple bits simultaneously across multiple wires (e.g., 8 bits at a time). While this offers high speed, it is limited by "crosstalk" and skew over long distances, making it suitable only for short-range communication (like internal computer buses). Serial transmission, used in networks like the Internet, sends one bit at a time over a single wire. Although seemingly slower, modern serial technologies (like USB or Ethernet) have overcome speed limitations through high-frequency signaling and are more cost-effective and reliable over long distances.
