What does the term 'Highway' refer to in the context of digital communications?

In the context of digital communications, the term 'Highway' typically refers to a digital serial-coded bit stream for signal transmission. This concept is central to understanding how data is transmitted over various mediums. A 'highway' in this sense represents a pathway or channel through which information travels, similar to how vehicles travel on a physical highway. The term emphasizes the efficiency and directionality of data transfer, critical for digital communications where information is encoded in bit streams and then transmitted to various devices.

This concept of a digital highway is essential because it underscores the importance of bandwidth and signal integrity, which directly affect the performance of data transmission. When discussing digital communications, the idea of a bit stream moving along a defined path is foundational for understanding network design, data integrity, and overall communication infrastructure.
